Thanks for the quick reply, but there's no problem with the SHA-1 due to :

1) The difference in our hash results is due to your applying SHA1(sid
+ from + to) rather than SHA1(sid + Stringprep.nameprep(from + to)),
which in this particular case simply transforms the from and to
variables to all lowercase. So your hash is based on a string
containing uppercase characters while mine was based on lowercase
characters, and the protocol specifically states that the JID's need
to be Stringprepped, so I assume my hash is correct.

2) I made the mistake of pasting the hash output in uppercase... it
should be all lowercase.

Anyone else have any ideas???
