-/**
- * Crypt_GPG is a package to use GPG from PHP
- *
- * This package provides an object oriented interface to GNU Privacy
- * Guard (GPG). It requires the GPG executable to be on the system.
- *
- * Though GPG can support symmetric-key cryptography, this package is intended
- * only to facilitate public-key cryptography.
- *
- * This file contains the main GPG class. The class in this file lets you
- * encrypt, decrypt, sign and verify data; import and delete keys; and perform
- * other useful GPG tasks.
- *
- * Example usage:
- * <code>
- * <?php
- * // encrypt some data
- * $gpg = new Crypt_GPG();
- * $gpg->addEncryptKey($mySecretKeyId);
- * $encryptedData = $gpg->encrypt($data);
- * ?>
- * </code>
- *
- * PHP version 5
