Hello,

latest kamailio versions support also SHA256 algorithm:

  - https://www.kamailio.org/docs/modules/stable/modules/auth.html#idp36720604

However, the main blocker in suing a different hashing algorithm are the sip client devices (mainly hardphones), which implement only MD5. If you implement your own client app, then you can extend kamailio to support whatever hashing you do in the client.

Then, of course you can use client side tls certificates for authentication, which should be better than any hashing algorithm.

Cheers,
Daniel

Hello,

I did some searches online and talked to some colleagues and it seems Kamailio only supports the traditional HTTP digest authentication, which uses MD5. I would like to know if any of you has been successful in using bcrypt/scrypt/pbkdf2 passwd hashing, instead of MD5, which has been deemed as obsolete and insecure a long time ago. Perhaps you've written your own auth module, or just modified the config script to call some other credential checking routine using a custom python/perl script (I'm thinking of doing the latter, of nothing better is available).

If any of you have done something like this, using bcrypt or any other current and secure hashing algorithm, I would appreciate some guidance.  If you haven't, aren't you concerned about storing MD5 password hashes in your database?

Note: if I can't find a good answer using this list, I will try the developer's list next.

Thanks in advance,

Martín.
