Returns the RFC1421 transformation of <stuff>, commonly known as Base64. Base64 converts three bytes of input into four Base64 digits. By definition Base64 digits are safe to send over text-only transmissions.
Alas, <stuff> cannot be binary data, because ircII function calls don't support non-C-strings.
The reverse transformation is b64decode.
Don't confuse this encoding with the one used by FiSH (popularized by eggdrop and other irc clients for encrypted messages). FiSH uses l64a encoding, and can be decoded using the xform FISH64 transform.
The string <stuff> converted into a sequence of Base64 digits.
