@head @module base64 @title base64: Base64 encoding and decoding
This module contains functions for base64 encoding and decoding of arbitrary narrow binary strings. Base64 allows representing arbitrary binary data using only a limited set of printable ASCII characters. Base64 encoding can be used, for example, in encoding email messages and in parts of the HTTP protocol.
The base64 alphabet contains the following characters (but = is only used for padding): @example A B C ... Z a b c ... z 0 1 2 3 ... 9 + / = @end
The Base64 encoding is defined in RFC 4648.
