     1.4 +This module is a Perl-only implementation of the cryptographic
     1.5 +cipher block chaining mode (CBC).
     1.6 +In combination with a block cipher such as AES or Blowfish,
     1.7 +you can encrypt and decrypt messages of arbitrarily long length.
     1.8 +The encrypted messages are compatible with the encryption format
     1.9 +used by the OpenSSL package.
    1.10 +
    1.11 +To use this module, you will first create a Crypt::CBC cipher
    1.12 +object with new().
    1.13 +At the time of cipher creation, you specify an encryption key
    1.14 +to use and, optionally, a block encryption algorithm.
    1.15 +You will then call the start() method to initialize the encryption
    1.16 +or decryption process, crypt() to encrypt or decrypt one or more
    1.17 +blocks of data, and lastly finish(), to pad and encrypt the final
    1.18 +block.
    1.19 +For your convenience, you can call the encrypt() and decrypt()
    1.20 +methods to operate on a whole data value at once.
