[Freeswitch-users] xml_curl directory - doing authentication in cgi, how to recreate user's password?

[Fraser Redmond]

Thanks Randy... but I think either I don't understand you, or you don't
understand me...

The password stored in the database has been hashed using mysql's ENCRYPT
function with a seed (because it's not good security policy to store a
password in any recoverable format.)

I think you're saying that the nonce is also a hashed version of the
password that also can't be reverted back to the original password - is
that right?

Which means that I now have two hashes which have been generated using
different methods, so there's no way to compare them - cant compare within
the cgi, and can't send the Freeswitch format back for Freeswitch to
compare.

If that's the case (and I'd still like to be clear on that), is it possible
to pass through the password in addition? (I'll be using https, so sending
without hashing is ok.)

Cheers,
Fraser
