* @brief Base64 encoding and decoding functions.
*
* This module contains base64 encoding and decoding functions. Base64
* encodes arbitrary octet strings as strings containing characters @c
* [A-Za-z0-9+/=]. Base64 is defined as part of MIME mail format, but it is
* used widely by other text-based protocols as well.
