7.x encryption.module encryption_get_hash_protocol()
6.x encryption.module encryption_get_hash_protocol()

This looks at the hash_algos() return to see if we can use SHA256, else return FALSE.

You can override which hash is used by adding $GLOBALS["encryption_hash"] = "PROTOCOL HERE"; to the settings.php file.
