Base64 Xtra performs base64 encoding and decoding of arbitrary binary strings into text strings that can be safely emailed or posted. The encoding scheme is defined in RFC 1521 (MIME (Multipurpose Internet Mail Extensions) Part One: Mechanisms for Specifying and Describing the Format of Internet Message Bodies, section 5.2, ``Base64 Content-Transfer-Encoding'') and is used for MIME email and various other Internet-related applications.

The TEA Xtra extension allows you to encipher the text strings and decipher it back. The Tiny Encryption Algorithm (TEA) is one of the fastest and most efficient cryptographic algorithms in existence. It is a Feistel cipher which uses operations from mixed (orthogonal) algebraic groups - XORs and additions in this case. It encrypts 64 data bits at a time using a 128-bit key.
