At my last job where I used SunOS 4.x, it was -+ defined to be 60.0 (look at the old INSTALL documentation), at -+ the last release had it changed to 100.0 since I now work with -+ Solaris2 and SVR4 boxes. -+ Thanks to Rory Chisholm <rchishol@math.ethz.ch> for pointing this -+ one out. -+ -+Version 3.12 08/05/95 -+ As pointed out by The Crypt Keeper <tck@bend.UCSD.EDU>, -+ my D_ENCRYPT macro in crypt() had an un-necessary variable. -+ It has been removed. -+ -+Version 3.11 03/05/95 -+ Added des_ede3_cbc_encrypt() which is cbc mode des with 3 keys -+ and one iv. It is a standard and I needed it for my SSL code. -+ It makes more sense to use this for triple DES than -+ 3cbc_encrypt(). I have also added (or should I say tested :-) -+ cfb64_encrypt() which is cfb64 but it will encrypt a partial -+ number of bytes - 3 bytes in 3 bytes out. Again this is for -+ my SSL library, as a form of encryption to use with SSL -+ telnet. -+ -+Version 3.10 22/03/95 -+ Fixed a bug in 3cbc_encrypt() :-(. When making repeated calls -+ to cbc3_encrypt, the 2 iv values that were being returned to -+ be used in the next call were reversed :-(. -+ Many thanks to Bill Wade <wade@Stoner.COM> for pointing out -+ this error. -+ -+Version 3.09 01/02/95 -+ Fixed des_random_key to far more random, it was rather feeble -+ with regards to picking the initial seed. The problem was -+ pointed out by Olaf Kirch <okir@monad.swb.de>. -+ -+Version 3.08 14/12/94 -+ Added Makefile.PL so libdes can be built into perl5. -+ Changed des_locl.h so RAND is always defined. -+ -+Version 3.07 05/12/94 -+ Added GNUmake and stuff so the library can be build with -+ glibc. -+ -+Version 3.06 30/08/94 -+ Added rpc_enc.c which contains _des_crypt. This is for use in -+ secure_rpc v 4.0 -+ Finally fixed the cfb_enc problems. -+ Fixed a few parameter parsing bugs in des (-3 and -b), thanks -+ to Rob McMillan <R.McMillan@its.gu.edu.au> -+ -+Version 3.05 21/04/94 -+ for unsigned long l; gcc does not produce ((l>>34) == 0) -+ This causes bugs in cfb_enc. -+ Thanks to Hadmut Danisch <danisch@ira.uka.de> -+ -+Version 3.04 20/04/94 -+ Added a version number to des.c and libdes.a -+ -+Version 3.03 12/01/94 -+ Fixed a bug in non zero iv in 3cbc_enc. -+ -+Version 3.02 29/10/93 -+ I now work in a place where there are 6+ architectures and 14+ -+ OS versions :-). -+ Fixed TERMIO definition so the most sys V boxes will work :-) -+ -+Release upon comp.sources.misc -+Version 3.01 08/10/93 -+ Added des_3cbc_encrypt() -+ -+Version 3.00 07/10/93 -+ Fixed up documentation. -+ quad_cksum definitely compatible with MIT's now. -+ -+Version 2.30 24/08/93 -+ Triple DES now defaults to triple cbc but can do triple ecb -+ with the -b flag. -+ Fixed some MSDOS uuen/uudecoding problems, thanks to -+ Added prototypes. -+ -+Version 2.22 29/06/93 -+ Fixed a bug in des_is_weak_key() which stopped it working :-( -+ thanks to engineering@MorningStar.Com. -+ -+Version 2.21 03/06/93 -+ des(1) with no arguments gives quite a bit of help. -+ Added -c (generate ckecksum) flag to des(1). -+ Added -3 (triple DES) flag to des(1). -+ Added cfb and ofb routines to the library. -+ -+Version 2.20 11/03/93 -+ Added -u (uuencode) flag to des(1). -+ I have been playing with byte order in quad_cksum to make it -+ compatible with MIT's version. All I can say is avid this -+ function if possible since MIT's output is endian dependent. -+ -+Version 2.12 14/10/92 -+ Added MSDOS specific macro in ecb_encrypt which gives a %70 -+ speed up when the code is compiled with turbo C. -+ -+Version 2.11 12/10/92 -+ Speedup in set_key (recoding of PC-1) -+ I now do it in 47 simple operations, down from 60. -+ Thanks to John Fletcher (john_fletcher@lccmail.ocf.llnl.gov) -+ for motivating me to look for a faster system :-) -+ The speedup is probably less that 1% but it is still 13 -+ instructions less :-). -+ -+Version 2.10 06/10/92 -+ The code now works on the 64bit ETA10 and CRAY without modifications or -+ #defines. I believe the code should work on any machine that -+ defines long, int or short to be 8 bytes long. -+ Thanks to Shabbir J. Safdar (shabby@mentor.cc.purdue.edu) -+ for helping me fix the code to run on 64bit machines (he had -+ access to an ETA10). -+ Thanks also to John Fletcher <john_fletcher@lccmail.ocf.llnl.gov> -+ for testing the routines on a CRAY. -+ read_password.c has been renamed to read_passwd.c -+ string_to_key.c has been renamed to string2key.c -+ -+Version 2.00 14/09/92 -+ Made mods so that the library should work on 64bit CPU's. -+ Removed all my uchar and ulong defs. To many different -+ versions of unix define them in their header files in too many -+ different combinations :-) -+ IRIX - Sillicon Graphics mods (mostly in read_password.c). -+ Thanks to Andrew Daviel (advax@erich.triumf.ca) -+ -+Version 1.99 26/08/92 -+ Fixed a bug or 2 in enc_read.c -+ Fixed a bug in enc_write.c -+ Fixed a pseudo bug in fcrypt.c (very obscure). -+ -+Version 1.98 31/07/92 -+ Support for the ETA10. This is a strange machine that defines -+ longs and ints as 8 bytes and shorts as 4 bytes. -+ Since I do evil things with long * that assume that they are 4 -+ bytes. Look in the Makefile for the option to compile for -+ this machine. quad_cksum appears to have problems but I -+ will don't have the time to fix it right now, and this is not -+ a function that uses DES and so will not effect the main uses -+ of the library. -+ -+Version 1.97 20/05/92 eay -+ Fixed the Imakefile and made some changes to des.h to fix some -+ problems when building this package with Kerberos v 4. -+ -+Version 1.96 18/05/92 eay -+ Fixed a small bug in string_to_key() where problems could -+ occur if des_check_key was set to true and the string -+ generated a weak key. -+ -+Patch2 posted to comp.sources.misc -+Version 1.95 13/05/92 eay -+ Added an alternative version of the D_ENCRYPT macro in -+ ecb_encrypt and fcrypt. Depending on the compiler, one version or the -+ other will be faster. This was inspired by -+ Dana How <how@isl.stanford.edu>, and her pointers about doing the -+ *(ulong *)((uchar *)ptr+(value&0xfc)) -+ vs -+ ptr[value&0x3f] -+ to stop the C compiler doing a <<2 to convert the long array index. -+ -+Version 1.94 05/05/92 eay -+ Fixed an incompatibility between my string_to_key and the MIT -+ version. When the key is longer than 8 chars, I was wrapping -+ with a different method. To use the old version, define -+ OLD_STR_TO_KEY in the makefile. Thanks to -+ viktor@newsu.shearson.com (Viktor Dukhovni). -+ -+Version 1.93 28/04/92 eay -+ Fixed the VMS mods so that echo is now turned off in -+ read_password. Thanks again to brennan@coco.cchs.su.oz.AU. -+ MSDOS support added. The routines can be compiled with -+ Turbo C (v2.0) and MSC (v5.1). Make sure MSDOS is defined. -+ -+Patch1 posted to comp.sources.misc -+Version 1.92 13/04/92 eay -+ Changed D_ENCRYPT so that the rotation of R occurs outside of -+ the loop. This required rotating all the longs in sp.h (now -+ called spr.h). Thanks to Richard Outerbridge <71755.204@CompuServe.COM> -+ speed.c has been changed so it will work without SIGALRM. If -+ times(3) is not present it will try to use ftime() instead. -+ -+Version 1.91 08/04/92 eay -+ Added -E/-D options to des(1) so it can use string_to_key. -+ Added SVR4 mods suggested by witr@rwwa.COM -+ Added VMS mods suggested by brennan@coco.cchs.su.oz.AU. If -+ anyone knows how to turn of tty echo in VMS please tell me or -+ implement it yourself :-). -+ Changed FILE *IN/*OUT to *DES_IN/*DES_OUT since it appears VMS -+ does not like IN/OUT being used. -+ -+Libdes posted to comp.sources.misc -+Version 1.9 24/03/92 eay -+ Now contains a fast small crypt replacement. -+ Added des(1) command. -+ Added des_rw_mode so people can use cbc encryption with -+ enc_read and enc_write. -+ -+Version 1.8 15/10/91 eay -+ Bug in cbc_cksum. -+ Many thanks to Keith Reynolds (keithr@sco.COM) for pointing this -+ one out. -+ -+Version 1.7 24/09/91 eay -+ Fixed set_key :-) -+ set_key is 4 times faster and takes less space. -+ There are a few minor changes that could be made. -+ -+Version 1.6 19/09/1991 eay -+ Finally go IP and FP finished. -+ Now I need to fix set_key. -+ This version is quite a bit faster that 1.51 -+ -+Version 1.52 15/06/1991 eay -+ 20% speedup in ecb_encrypt by changing the E bit selection -+ to use 2 32bit words. This also required modification of the -+ sp table. There is still a way to speedup the IP and IP-1 -+ (hints from outer@sq.com) still working on this one :-(. -+ -+Version 1.51 07/06/1991 eay -+ Faster des_encrypt by loop unrolling -+ Fixed bug in quad_cksum.c (thanks to hughes@logos.ucs.indiana.edu) -+ -+Version 1.50 28/05/1991 eay -+ Optimised the code a bit more for the sparc. I have improved the -+ speed of the inner des_encrypt by speeding up the initial and -+ final permutations. -+ -+Version 1.40 23/10/1990 eay -+ Fixed des_random_key, it did not produce a random key :-( -+ -+Version 1.30 2/10/1990 eay -+ Have made des_quad_cksum the same as MIT's, the full package -+ should be compatible with MIT's -+ Have tested on a DECstation 3100 -+ Still need to fix des_set_key (make it faster). -+ Does des_cbc_encrypts at 70.5k/sec on a 3100. -+ -+Version 1.20 18/09/1990 eay -+ Fixed byte order dependencies. -+ Fixed (I hope) all the word alignment problems. -+ Speedup in des_ecb_encrypt. -+ -+Version 1.10 11/09/1990 eay -+ Added des_enc_read and des_enc_write. -+ Still need to fix des_quad_cksum. -+ Still need to document des_enc_read and des_enc_write. -+ -+Version 1.00 27/08/1990 eay -+ ---- /dev/null Tue Mar 11 13:02:56 2003 -+++ linux/net/ipsec/des/asm/des-586.pl Mon Feb 9 13:51:03 2004 -@@ -0,0 +1,251 @@ -+#!/usr/local/bin/perl -+# -+# The inner loop instruction sequence and the IP/FP modifications are from -+# Svend Olaf Mikkelsen <svolaf@inet.uni-c.dk> -+# -+ -+push(@INC,"perlasm","../../perlasm");

So due to this, I have lowered myself to do -+assembler for the inner DES routines in libdes :-). -+ -+The file to implement in assembler is des_enc.c.

The only difference between the 4 functions is that -+des_encrypt2() does not perform IP() or FP() on the data (this is an -+optimization for when doing triple DES and des_encrypt3() and des_decrypt3() -+perform triple des. The triple DES routines are in here because it does -+make a big difference to have them located near the des_encrypt2 function -+at link time.. -+ -+Now as we all know, there are lots of different operating systems running on -+x86 boxes, and unfortunately they normally try to make sure their assembler -+formating is not the same as the other peoples. -+The 4 main formats I know of are -+Microsoft Windows 95/Windows NT -+Elf Includes Linux and FreeBSD(?). -+a.out The older Linux. -+Solaris Same as Elf but different comments :-(. -+ -+Now I was not overly keen to write 4 different copies of the same code, -+so I wrote a few perl routines to output the correct assembler, given -+a target assembler type. This code is ugly and is just a hack. -+The libraries are x86unix.pl and x86ms.pl. -+des586.pl, des686.pl and des-som[23].pl are the programs to actually -+generate the assembler. -+ -+So to generate elf assembler -+perl des-som3.pl elf >dx86-elf.s -+For Windows 95/NT -+perl des-som2.pl win32 >win32.asm -+ -+[ update 4 Jan 1996 ] -+I have added another way to do things. -+perl des-som3.pl cpp >dx86-cpp.s -+generates a file that will be included by dx86unix.cpp when it is compiled. -+To build for elf, a.out, solaris, bsdi etc, -+cc -E -DELF asm/dx86unix.cpp | as -o asm/dx86-elf.o -+cc -E -DSOL asm/dx86unix.cpp | as -o asm/dx86-sol.o -+cc -E -DOUT asm/dx86unix.cpp | as -o asm/dx86-out.o -+cc -E -DBSDI asm/dx86unix.cpp | as -o asm/dx86bsdi.o -+This was done to cut down the number of files in the distribution. -+ -+Now the ugly part. I acquired my copy of Intels -+"Optimization's For Intel's 32-Bit Processors" and found a few interesting -+things. First, the aim of the exersize is to 'extract' one byte at a time -+from a word and do an array lookup. This involves getting the byte from -+the 4 locations in the word and moving it to a new word and doing the lookup. -+The most obvious way to do this is -+xor eax, eax # clear word -+movb al, cl # get low byte -+xor edi DWORD PTR 0x100+des_SP[eax] # xor in word -+movb al, ch # get next byte -+xor edi DWORD PTR 0x300+des_SP[eax] # xor in word -+shr ecx 16 -+which seems ok. For the pentium, this system appears to be the best. -+One has to do instruction interleaving to keep both functional units -+operating, but it is basically very efficient. -+ -+Now the crunch. When a full register is used after a partial write, eg. -+mov al, cl -+xor edi, DWORD PTR 0x100+des_SP[eax] -+386 - 1 cycle stall -+486 - 1 cycle stall -+586 - 0 cycle stall -+686 - at least 7 cycle stall (page 22 of the above mentioned document). -+ -+So the technique that produces the best results on a pentium, according to -+the documentation, will produce hideous results on a pentium pro. -+ -+To get around this, des686.pl will generate code that is not as fast on -+a pentium, should be very good on a pentium pro. -+mov eax, ecx # copy word -+shr ecx, 8 # line up next byte -+and eax, 0fch # mask byte -+xor edi DWORD PTR 0x100+des_SP[eax] # xor in array lookup -+mov eax, ecx # get word -+shr ecx 8 # line up next byte -+and eax, 0fch # mask byte -+xor edi DWORD PTR 0x300+des_SP[eax] # xor in array lookup -+ -+Due to the execution units in the pentium, this actually works quite well. -+For a pentium pro it should be very good. This is the type of output -+Visual C++ generates. -+ -+There is a third option. instead of using -+mov al, ch -+which is bad on the pentium pro, one may be able to use -+movzx eax, ch -+which may not incur the partial write penalty. On the pentium, -+this instruction takes 4 cycles so is not worth using but on the -+pentium pro it appears it may be worth while. I need access to one to -+experiment :-). -+ -+eric (20 Oct 1996) -+ -+22 Nov 1996 - I have asked people to run the 2 different version on pentium -+pros and it appears that the intel documentation is wrong. The -+mov al,bh is still faster on a pentium pro, so just use the des586.pl -+install des686.pl -+ -+3 Dec 1996 - I added des_encrypt3/des_decrypt3 because I have moved these -+functions into des_enc.c because it does make a massive performance -+difference on some boxes to have the functions code located close to -+the des_encrypt2() function. -+ -+9 Jan 1997 - des-som2.pl is now the correct perl script to use for -+pentiums. It contains an inner loop from -+Svend Olaf Mikkelsen <svolaf@inet.uni-c.dk> which does raw ecb DES calls at -+273,000 per second. He had a previous version at 250,000 and the best -+I was able to get was 203,000. The content has not changed, this is all -+due to instruction sequencing (and actual instructions choice) which is able -+to keep both functional units of the pentium going. -+We may have lost the ugly register usage restrictions when x86 went 32 bit -+but for the pentium it has been replaced by evil instruction ordering tricks. -+ -+13 Jan 1997 - des-som3.pl, more optimizations from Svend Olaf. -+raw DES at 281,000 per second on a pentium 100. -+ ---- /dev/null Tue Mar 11 13:02:56 2003 -+++ linux/net/ipsec/des/cbc_enc.c Mon Feb 9 13:51:03 2004 -@@ -0,0 +1,135 @@ -+/* crypto/des/cbc_enc.c */ -+/* Copyright (C) 1995-1997 Eric Young (eay@cryptsoft.com) -+ * All rights reserved. -+ * -+ * This package is an SSL implementation written -+ * by Eric Young (eay@cryptsoft.com). -+ * The implementation was written so as to conform with Netscapes SSL. -+ * -+ * This library is free for commercial and non-commercial use as long as -+ * the following conditions are aheared to.

So the key is sort of 24 bytes. -+ This is much better than cbc des. -+ -+void des_3cbc_encrypt( -+des_cblock *input, -+des_cblock *output, -+long length, -+des_key_schedule sk1, -+des_key_schedule sk2, -+des_cblock *ivec1, -+des_cblock *ivec2, -+int enc); -+ This function is flawed, do not use it. I have left it in the -+ library because it is used in my des(1) program and will function -+ correctly when used by des(1). If I removed the function, people -+ could end up unable to decrypt files. -+ This routine implements outer triple cbc encryption using 2 ks and -+ 2 ivec's. Use des_ede2_cbc_encrypt() instead. -+ -+void des_ede3_cbc_encrypt( -+des_cblock *input, -+des_cblock *output, -+long length, -+des_key_schedule ks1, -+des_key_schedule ks2, -+des_key_schedule ks3, -+des_cblock *ivec, -+int enc); -+ This function implements inner triple CBC DES encryption with 3 -+ keys. What this means is that each 'DES' operation -+ inside the cbc mode is really an C=E(ks3,D(ks2,E(ks1,M))). -+ Again, this is cbc mode so an ivec is requires. -+ This mode is used by SSL. -+ There is also a des_ede2_cbc_encrypt() that only uses 2 -+ des_key_schedule's, the first being reused for the final -+ encryption. C=E(ks1,D(ks2,E(ks1,M))). This form of triple DES -+ is used by the RSAref library. -+ -+void des_pcbc_encrypt( -+des_cblock *input, -+des_cblock *output, -+long length, -+des_key_schedule ks, -+des_cblock *ivec, -+int enc); -+ This is Propagating Cipher Block Chaining mode of DES. It is used -+ by Kerberos v4. It's parameters are the same as des_ncbc_encrypt(). -+ -+void des_cfb_encrypt( -+unsigned char *in, -+unsigned char *out, -+int numbits, -+long length, -+des_key_schedule ks, -+des_cblock *ivec, -+int enc); -+ Cipher Feedback Back mode of DES. This implementation 'feeds back' -+ in numbit blocks. The input (and output) is in multiples of numbits -+ bits. numbits should to be a multiple of 8 bits. Length is the -+ number of bytes input. If numbits is not a multiple of 8 bits, -+ the extra bits in the bytes will be considered padding. So if -+ numbits is 12, for each 2 input bytes, the 4 high bits of the -+ second byte will be ignored. So to encode 72 bits when using -+ a numbits of 12 take 12 bytes. To encode 72 bits when using -+ numbits of 9 will take 16 bytes. To encode 80 bits when using -+ numbits of 16 will take 10 bytes. etc, etc. This padding will -+ apply to both input and output. -+ -+ -+void des_cfb64_encrypt( -+unsigned char *in, -+unsigned char *out, -+long length, -+des_key_schedule ks, -+des_cblock *ivec, -+int *num, -+int enc); -+ This is one of the more useful functions in this DES library, it -+ implements CFB mode of DES with 64bit feedback. Why is this -+ useful you ask? Because this routine will allow you to encrypt an -+ arbitrary number of bytes, no 8 byte padding. Each call to this -+ routine will encrypt the input bytes to output and then update ivec -+ and num. num contains 'how far' we are though ivec. If this does -+ not make much sense, read more about cfb mode of DES :-). -+ -+void des_ede3_cfb64_encrypt( -+unsigned char *in, -+unsigned char *out, -+long length, -+des_key_schedule ks1, -+des_key_schedule ks2, -+des_key_schedule ks3, -+des_cblock *ivec, -+int *num, -+int enc); -+ Same as des_cfb64_encrypt() accept that the DES operation is -+ triple DES. As usual, there is a macro for -+ des_ede2_cfb64_encrypt() which reuses ks1. -+ -+void des_ofb_encrypt( -+unsigned char *in, -+unsigned char *out, -+int numbits, -+long length, -+des_key_schedule ks, -+des_cblock *ivec); -+ This is a implementation of Output Feed Back mode of DES. It is -+ the same as des_cfb_encrypt() in that numbits is the size of the -+ units dealt with during input and output (in bits). -+ -+void des_ofb64_encrypt( -+unsigned char *in, -+unsigned char *out, -+long length, -+des_key_schedule ks, -+des_cblock *ivec, -+int *num); -+ The same as des_cfb64_encrypt() except that it is Output Feed Back -+ mode. -+ -+void des_ede3_ofb64_encrypt( -+unsigned char *in, -+unsigned char *out, -+long length, -+des_key_schedule ks1, -+des_key_schedule ks2, -+des_key_schedule ks3, -+des_cblock *ivec, -+int *num); -+ Same as des_ofb64_encrypt() accept that the DES operation is -+ triple DES. As usual, there is a macro for -+ des_ede2_ofb64_encrypt() which reuses ks1. -+ -+int des_read_pw_string( -+char *buf, -+int length, -+char *prompt, -+int verify); -+ This routine is used to get a password from the terminal with echo -+ turned off. Buf is where the string will end up and length is the -+ size of buf. Prompt is a string presented to the 'user' and if -+ verify is set, the key is asked for twice and unless the 2 copies -+ match, an error is returned. A return code of -1 indicates a -+ system error, 1 failure due to use interaction, and 0 is success. -+ -+unsigned long des_cbc_cksum( -+des_cblock *input, -+des_cblock *output, -+long length, -+des_key_schedule ks, -+des_cblock *ivec); -+ This function produces an 8 byte checksum from input that it puts in -+ output and returns the last 4 bytes as a long. The checksum is -+ generated via cbc mode of DES in which only the last 8 byes are -+ kept. I would recommend not using this function but instead using -+ the EVP_Digest routines, or at least using MD5 or SHA. This -+ function is used by Kerberos v4 so that is why it stays in the -+ library. -+ -+char *des_fcrypt( -+const char *buf, -+const char *salt -+char *ret); -+ This is my fast version of the unix crypt(3) function. This version -+ takes only a small amount of space relative to other fast -+ crypt() implementations. This is different to the normal crypt -+ in that the third parameter is the buffer that the return value -+ is written into. It needs to be at least 14 bytes long. This -+ function is thread safe, unlike the normal crypt. -+ -+char *crypt( -+const char *buf, -+const char *salt); -+ This function calls des_fcrypt() with a static array passed as the -+ third parameter. This emulates the normal non-thread safe semantics -+ of crypt(3). -+ -+void des_string_to_key( -+char *str, -+des_cblock *key); -+ This function takes str and converts it into a DES key. I would -+ recommend using MD5 instead and use the first 8 bytes of output. -+ When I wrote the first version of these routines back in 1990, MD5 -+ did not exist but I feel these routines are still sound. This -+ routines is compatible with the one in MIT's libdes. -+ -+void des_string_to_2keys( -+char *str, -+des_cblock *key1, -+des_cblock *key2); -+ This function takes str and converts it into 2 DES keys. -+ I would recommend using MD5 and using the 16 bytes as the 2 keys. -+ I have nothing against these 2 'string_to_key' routines, it's just -+ that if you say that your encryption key is generated by using the -+ 16 bytes of an MD5 hash, every-one knows how you generated your -+ keys. -+ -+int des_read_password( -+des_cblock *key, -+char *prompt, -+int verify); -+ This routine combines des_read_pw_string() with des_string_to_key(). -+ -+int des_read_2passwords( -+des_cblock *key1, -+des_cblock *key2, -+char *prompt, -+int verify); -+ This routine combines des_read_pw_string() with des_string_to_2key(). -+ -+void des_random_seed( -+des_cblock key); -+ This routine sets a starting point for des_random_key(). -+ -+void des_random_key( -+des_cblock ret); -+ This function return a random key. Make sure to 'seed' the random -+ number generator (with des_random_seed()) before using this function. -+ I personally now use a MD5 based random number system. -+ -+int des_enc_read( -+int fd, -+char *buf, -+int len, -+des_key_schedule ks, -+des_cblock *iv); -+ This function will write to a file descriptor the encrypted data -+ from buf. This data will be preceded by a 4 byte 'byte count' and -+ will be padded out to 8 bytes. The encryption is either CBC of -+ PCBC depending on the value of des_rw_mode. If it is DES_PCBC_MODE, -+ pcbc is used, if DES_CBC_MODE, cbc is used. The default is to use -+ DES_PCBC_MODE. -+ -+int des_enc_write( -+int fd, -+char *buf, -+int len, -+des_key_schedule ks, -+des_cblock *iv); -+ This routines read stuff written by des_enc_read() and decrypts it. -+ I have used these routines quite a lot but I don't believe they are -+ suitable for non-blocking io. If you are after a full -+ authentication/encryption over networks, have a look at SSL instead. -+ -+unsigned long des_quad_cksum( -+des_cblock *input, -+des_cblock *output, -+long length, -+int out_count, -+des_cblock *seed); -+ This is a function from Kerberos v4 that is not anything to do with -+ DES but was needed. It is a cksum that is quicker to generate than -+ des_cbc_cksum(); I personally would use MD5 routines now. -+===== -+Modes of DES -+Quite a bit of the following information has been taken from -+ AS 2805.5.2 -+ Australian Standard -+ Electronic funds transfer - Requirements for interfaces, -+ Part 5.2: Modes of operation for an n-bit block cipher algorithm -+ Appendix A -+ -+There are several different modes in which DES can be used, they are -+as follows. -+ -+Electronic Codebook Mode (ECB) (des_ecb_encrypt()) -+- 64 bits are enciphered at a time. -+- The order of the blocks can be rearranged without detection. -+- The same plaintext block always produces the same ciphertext block -+ (for the same key) making it vulnerable to a 'dictionary attack'. -+- An error will only affect one ciphertext block. -+ -+Cipher Block Chaining Mode (CBC) (des_cbc_encrypt()) -+- a multiple of 64 bits are enciphered at a time. -+- The CBC mode produces the same ciphertext whenever the same -+ plaintext is encrypted using the same key and starting variable. -+- The chaining operation makes the ciphertext blocks dependent on the -+ current and all preceding plaintext blocks and therefore blocks can not -+ be rearranged. -+- The use of different starting variables prevents the same plaintext -+ enciphering to the same ciphertext. -+- An error will affect the current and the following ciphertext blocks. -+ -+Cipher Feedback Mode (CFB) (des_cfb_encrypt()) -+- a number of bits (j) <= 64 are enciphered at a time. -+- The CFB mode produces the same ciphertext whenever the same -+ plaintext is encrypted using the same key and starting variable. -+- The chaining operation makes the ciphertext variables dependent on the -+ current and all preceding variables and therefore j-bit variables are -+ chained together and can not be rearranged. -+- The use of different starting variables prevents the same plaintext -+ enciphering to the same ciphertext. -+- The strength of the CFB mode depends on the size of k (maximal if -+ j == k). In my implementation this is always the case. -+- Selection of a small value for j will require more cycles through -+ the encipherment algorithm per unit of plaintext and thus cause -+ greater processing overheads. -+- Only multiples of j bits can be enciphered. -+- An error will affect the current and the following ciphertext variables. -+ -+Output Feedback Mode (OFB) (des_ofb_encrypt()) -+- a number of bits (j) <= 64 are enciphered at a time. -+- The OFB mode produces the same ciphertext whenever the same -+ plaintext enciphered using the same key and starting variable. More -+ over, in the OFB mode the same key stream is produced when the same -+ key and start variable are used. Consequently, for security reasons -+ a specific start variable should be used only once for a given key. -+- The absence of chaining makes the OFB more vulnerable to specific attacks. -+- The use of different start variables values prevents the same -+ plaintext enciphering to the same ciphertext, by producing different -+ key streams. -+- Selection of a small value for j will require more cycles through -+ the encipherment algorithm per unit of plaintext and thus cause -+ greater processing overheads. -+- Only multiples of j bits can be enciphered. -+- OFB mode of operation does not extend ciphertext errors in the -+ resultant plaintext output. Every bit error in the ciphertext causes -+ only one bit to be in error in the deciphered plaintext. -+- OFB mode is not self-synchronising. If the two operation of -+ encipherment and decipherment get out of synchronism, the system needs -+ to be re-initialised. -+- Each re-initialisation should use a value of the start variable -+ different from the start variable values used before with the same -+ key. The reason for this is that an identical bit stream would be -+ produced each time from the same parameters. This would be -+ susceptible to a ' known plaintext' attack. -+ -+Triple ECB Mode (des_ecb3_encrypt()) -+- Encrypt with key1, decrypt with key2 and encrypt with key3 again. -+- As for ECB encryption but increases the key length to 168 bits. -+ There are theoretic attacks that can be used that make the effective -+ key length 112 bits, but this attack also requires 2^56 blocks of -+ memory, not very likely, even for the NSA. -+- If both keys are the same it is equivalent to encrypting once with -+ just one key. -+- If the first and last key are the same, the key length is 112 bits. -+ There are attacks that could reduce the key space to 55 bit's but it -+ requires 2^56 blocks of memory. -+- If all 3 keys are the same, this is effectively the same as normal -+ ecb mode. -+ -+Triple CBC Mode (des_ede3_cbc_encrypt()) -+- Encrypt with key1, decrypt with key2 and then encrypt with key3. -+- As for CBC encryption but increases the key length to 168 bits with -+ the same restrictions as for triple ecb mode. ---- /dev/null Tue Mar 11 13:02:56 2003 -+++ linux/net/ipsec/des/des_enc.c Mon Feb 9 13:51:03 2004 -@@ -0,0 +1,502 @@ -+/* crypto/des/des_enc.c */ -+/* Copyright (C) 1995-1997 Eric Young (eay@cryptsoft.com) -+ * All rights reserved. -+ * -+ * This package is an SSL implementation written -+ * by Eric Young (eay@cryptsoft.com). -+ * The implementation was written so as to conform with Netscapes SSL. -+ * -+ * This library is free for commercial and non-commercial use as long as -+ * the following conditions are aheared to.

Code 256 represents the -+ end-of-block. Note however that the static length tree defines -+ 288 codes just to fill out the Huffman codes. Codes 286 and 287 -+ cannot be used though, since there is no length base or extra bits -+ defined for them.

Therefore, to output three times the length, you output -+ three codes (1+1+1), whereas to output four times the same length, -+ you only need two codes (1+3). Hmm. -+ 10.
