| Hans-G?nter@24190 | 1 This module is a Perl-only implementation of the cryptographic |
| Hans-G?nter@24190 | 2 cipher block chaining mode (CBC). |
| Hans-G?nter@24190 | 3 In combination with a block cipher such as AES or Blowfish, |
| Hans-G?nter@24190 | 4 you can encrypt and decrypt messages of arbitrarily long length. |
| Hans-G?nter@24190 | 5 The encrypted messages are compatible with the encryption format |
| Hans-G?nter@24190 | 6 used by the OpenSSL package. |
| Hans-G?nter@24190 | 7 |
| Hans-G?nter@24190 | 8 To use this module, you will first create a Crypt::CBC cipher |
| Hans-G?nter@24190 | 9 object with new(). |
| Hans-G?nter@24190 | 10 At the time of cipher creation, you specify an encryption key |
| Hans-G?nter@24190 | 11 to use and, optionally, a block encryption algorithm. |
| Hans-G?nter@24190 | 12 You will then call the start() method to initialize the encryption |
| Hans-G?nter@24190 | 13 or decryption process, crypt() to encrypt or decrypt one or more |
| Hans-G?nter@24190 | 14 blocks of data, and lastly finish(), to pad and encrypt the final |
| Hans-G?nter@24190 | 15 block. |
| Hans-G?nter@24190 | 16 For your convenience, you can call the encrypt() and decrypt() |
| Hans-G?nter@24190 | 17 methods to operate on a whole data value at once. |
