in reply to Crypto Module

Crypt::CBC is a convenience wrapper that takes care of the key setup and padding for you. It should be much easier to use than for example the AES module directly.

    I agree fully. It handles at least three important jobs:

    • Padding: Adjusting the length of the message so it can be encrypted, and removing the adjustments when decrypting.
    • Salting: Using a different key for each message.
    • Chaining: Using a different key for each block of the message.
