This module implements a wrapper around OpenSSL. Specifically, it wraps the methods related to the US Government's Advanced Encryption Standard (the Rijndael algorithm). This module is compatible with Crypt::CBC (and likely other modules that utilize a block cipher to make a stream cipher). This module is an alternative to the implementation provided by Crypt::Rijndael which implements AES itself. In contrast, this module is simply a wrapper around the OpenSSL library. The Crypt::Rijndael implementation seems to produce inaccurate results on 64-bit x86 machines. By using OpenSSL, this module aims to avoid architecture specific problems, allowing the OpenSSL maintainers to overcome such issues.
