Hi,

I'm trying to figure out the easiest way to authenticate users against Oracle for passwords that are brought into the database from an outside source and are already encrypted using SSHA.

The scenario is that the passwords are pulled into Oracle (from an external LDAP directory) and then when the user tries to authenticate, the authenticating application is able to pass the unencrypted value entered by the user into a stored procedure in Oracle. From there I need to apply the same salted hash used to generate the value already in the database to do a match.

So, from within this stored procedure I either need to call an external process to hash the text entered by the user or have Oracle do this (if it's supported). We already do this with a different encryption algorithm for other users but now need to add in support for SSHA (coming from this secondary source) and I haven't had much luck finding info on how to do this.

Any suggestions?

I don't understand what you are saying but have a look at DBMS_CRYPTO package. It can encrypt with SHA-1 algorithm.

Thanks Michel, but I don't see any info in here about support for a salted hash (SSHA). If anyone knows if this is supported in the package, please let me know. Otherwise I would need to make a call to an external package that can handle this (and I'm trying to avoid this).

I don't know abuot SSHA but if it is not supported, you can add a Java function/class inside Oracle JVM and use it.

Thanks, it looks like I may need to go that route.
