def fromBase64(s): (source)

Decode base64 encoded string.

This helper performs regular decoding of a base64 encoded string, but also rejects any characters that are not in the base64 alphabet and padding occurring elsewhere from the last or last two characters, as specified in section 14.9 of RFC 3920. This safeguards against various attack vectors among which the creation of a covert channel that "leaks" information.

def get_mechanisms(xs): (source)

Parse the SASL feature to extract the available mechanism names.
