supported encryption

[Rakotomandimby Mihamina]

Hi all,
At the moment, our FreeRaduis(v1.x) is looking up users in a PGSQL
database, with clear username and clear password in the fields.

We would like to switch it to FreeRadius (v2.x) and by the way, crypt
(SHA, just crypt(),...) the password in the Database. What encryption is
supported by FreeRadius, so that I could just make the PGSQL query with
the encrypted password?

Thank you.
