An extension based upon the principle of stacked channels. Provides several conversions, hash algorithms and other transformations.
For example Base64 encoding and decoding, zlib/bzlib compression, SHA, MD5, etc. Thus well-suited to handle mime-Mail. An add-on, Trfcrypt, provides Encryption and Decryption facilities.
