It is impossible to form a response to XMPP ...

[Dr.Rihman]

 Attempted to make the implementation of a procedure that generates response to XMPP (per RFC 2831) - did not work: (

Who can help?

The procedure takes the following arguments: uname (username), realm (server address, for example "jabber.ru"), passw (password), nonce (singular value received from the server), cnonce (randomly generated for the session). Output - Digest MD5.

Arguments are prepared, but did not work ((

Possible problem: it is impossible to implement a formula to calculate the response. (Formula took here: http://tools.ietf.org/html/rfc2831)

Please help with the implementation of this formula, it is very necessary!
