This is from RFC 6120, section 6.4.2: http://xmpp.org/rfcs/rfc6120.html#sasl-process-neg-initiate and 6.4.6: http://xmpp.org/rfcs/rfc6120.html#sasl-process-neg-success In short, the '=' is used to differentiate "no data" and "empty data" within the SASL element. On receiving '=', you need to skip base64 decoding and just treat it as an empty string.
