I've looked at some code that implements the encoding, but reading the specification (the intent) would be most useful. One question in particular springs to mind: can usernames and passwords be made up of multi-byte characters, and how does this affect the MD5 encoding? Thanks. P.S. Many thanks for the help with my character string encoding questions. I have that all working nicely, now. :-) ^ permalink raw reply [nested|flat] 2+ messages in thread

That string is encoded twice, once with the username string, and another time with the random salt sent from the server. > One question in particular springs to mind: can usernames and passwords > be made up of multi-byte characters, and how does this affect the MD5 > encoding? It should be fine, I think. The encoding is just a string if bytes to MD5, and there is no encoding conversion done as part of that transfer. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073 ^ permalink raw reply [nested|flat] 2+ messages in thread
