public class WHIRLPOOLwithECDSAPlainSignature

extends ECDSAPlainSignature

Signature engine for the ECDSA signature algorithm as defined by the German BSI Technical Guideline TR-03111 using WHIRLPOOL as hash algorithm. The signature value is encoded as (r || s) and not wrapped into a SEQUENCE as done by X9.62. If the hash length is larger than the domain parameter length the hash is not truncated like in X9.62; rather it is reduced modulo n, the order of the base point G.
