[h323implementers] cryptoTokens & md5 password

Hi!

I'm developing h323 gatekeeper implementation and now I have to make authorization check on it usign H323-ID/password pair in cryptoTokens. As I understood, to make encrypted token (I use md5) we have to know password and some other data. To check cryptoToken in side of the gatekeeper I have to make the same encrypted token and compare them.

So this is the question: does it means, that I have to save opened password or password, encrypted by some cipher, but I can not use md5-encrypted passwords (because I cannot decrypt them to make cryptoToken). Or there are some another way to provide an authorisation usign cryptoTokens and keep only hash of password on the gk-side?
