All Implemented Interfaces:

PKCS11EngineClass

public class EcDsaKeyPairGenerator
extends PKCS11KeyPairGenerator

An engine class for generating ECDSA key-pairs on a token. The application must call initialize(AlgorithmParameterSpec, SecureRandom) before calling generateKeyPair().

This implementation only supports the following key sizes:

• 163 bit keys for the c2pnb163v1 curve
• 176 bit keys for the c2pnb176w1 curve
• 191 bit keys for the c2tnb191v1 curve
• 192 bit keys for the prime192v1 curve, which is the default
• 208 bit keys for the c2pnb208w1 curve
• 239 bit keys for the prime239v1 curve
• 224 bit keys for the secp224r1 curve
• 256 bit keys for the prime256v1 curve
