Well, maybe it'd fit if crypt_all() can produce more output indices than we had keys set with set_key(). (A formats interface enhancement that is planned anyway.) Then get_key() would generate and return the actual "virtual keys" (if there's a match on a key that was never tried by the high-level code explicitly). I just thought I'd have this "bookmarked" in here. Alexander
