Crypt Class is a wrapper around the libmcrypt
functions that offers a simplified interface and
new features such as embedded IV. It provides
an easy way to encrypt and decrypt data, and
automatically creates and extracts IVs, storing
them along with the encrypted string. It
supports all of the ciphers in libmcrypt,
including Twofish, Blowfish, and AES, and
makes it easy to switch between them.
