mcrypt v0.1.1 Mcrypt

This is a thin wrapper around libmcrypt.

Please see the linked man page for details on the available ciphers and modes.

Summary

Types

Functions

decrypt(ciphertext, algorithm, mode, key, iv)

Wraps libmcrypt's mdecrypt_generic, including setup and teardown of the cipher module

decrypt!(ciphertext, algorithm, mode, key, iv)

Like decrypt, but raises on error

encrypt(plaintext, algorithm, mode, key, iv)

Wraps libmcrypt's mcrypt_generic, including setup and teardown of the cipher module

encrypt!(plaintext, algorithm, mode, key, iv)

Like encrypt, but raises on error
