the same than ?? the ciphers that don't use DIR_SIGN ?

the constraints on cipher and signature classes are not defined
by card provider but by SUN thru the JavaCard API.
(a provider may or not provide a concrete implementation of a
mechanism but when provided it shall conform to SUN specifications).

DSA & ECDSA mechanisms are only available with signature classe,
so to obtain such signatures you must let the card hashs the data;
you can not use a cipher class together with a pre-computed digest.
