Hello Daniel, Thank you for your answer, this is exactly what I need. Modification of the auth module seems to be a better solution, but this lead to some questions for me...
- Could you explain a little bit how the auth module is working? Which files do I have to modify to change the hash method? - If I used another auth_* module to get username / password, the modification in the auth module is enough for the www_authentication? In other words, the authentication is always done in this module? Even If I use auth_radius or auth_diameter or a self-made auth_* module?

But I think it will be simpler to extend auth module to support different hashing algorithm. The code for computing shaX is already in kamailio (used for shaX transformations), so the change in auth should be about advertising and detecting when the new algorithm has to be used.

In this situation, would it be possible to change the authentication algorithm by either modifying Kamailio scripts or writing an external module to do that? As far as I know, the authentication response is calculated as follow (standard HTTP Digest authentication) : HA1=MD5(username:realm:password) HA2=MD5(method:digestURI) response=MD5(HA1:nonce:HA2) For that, I have to save ha1 and ha1b values in the DB with the SHA function directly (with a trigger for example), and then change the authentication method too. What is the best solution to do that? Does a module already exists? Thank you!
