Another issue:

An old Asterisk user, Kapejod, did some tests the other day. It took just a few minutes to brute-force a four character password with MD5.

I think we should be among the first to migrate to SHA256 auth, so please code in a way that you can select algorithm or force one.

Also think about using TLS client certs for auth, especially on trunks to other SIP servers.


Perhaps a long shot, but why can't asterisk use use the authentication
methods already existing on systems?
Something like pam_asterisk ?
If possible, you could use anything (pwd, ldap, kerberos, pkcs11, ...)

Or do i over-simplify things...
