Base64 and line breaks

Hi,

I'm running into an interoperability problem regarding the base64
encoding of blob data during a SASL profile exchange. One side (the Java
side) is using the mime encoding rules and inserting a line break after
every 76 characters of base64 encoded data. The other side (the C side)
is expecting a continuous stream of base64 data with no line breaks.

Which side is right (the BEEP RFC simply states that blob data must be
base64 encoded for SASL exchanges, it doesn't say whether the blob
should follow mime rules for that data or not)?

Thanks - Paul.
