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.
