Related Algorithms

The following two algorithms, base64 and the process of XORing a value against a key, are sometimes used to encode data in a way that looks like encryption. Make no mistake, though: any algorithm that does not use a mathematically rigorous cryptographic algorithm should never be used for encryption. We feel that it is important to mention these methods, however, because they have practical application within and around the encryption and hashing algorithms discussed earlier.

base64

base64 is an encoding algorithm rather than an encryption algorithm. Originally developed to allow transfer of binary email attachments by transforming them into printable characters, it has found considerable use for what some might prefer to call ...
