Interface ECDSAParams

All Known Implementing Classes:

ECDSAParameter

public interface ECDSAParams

Common interface for ECDSA domain parameters. The domain parameters are the base point G, which is a generator of the subgroup. The order of the subgroup r and, if known, the co-factor k which is #E / r.

Method Summary

ECPoint	getG() The generator of the subgroub of order r.
java.math.BigInteger	getK()
java.lang.String	getOID()
java.math.BigInteger	getR()
java.math.BigInteger	getS()
