int size,
ECPrivateKeyParameters sKey,
ECPublicKeyParameters vKey,
ISigner sgr,
SecureRandom k,
byte[] message,
BigInteger r,
BigInteger s)
{
sgr.Init(true, new ParametersWithRandom(sKey, k));
sgr.BlockUpdate(message, 0, message.Length);
byte[] sigBytes = sgr.GenerateSignature();
sgr.Init(false, vKey);
sgr.BlockUpdate(message, 0, message.Length);
if (!sgr.VerifySignature(sigBytes))
{
Fail(size + " bit EC verification failed");
}
BigInteger[] sig = derDecode(sigBytes);
if (!r.Equals(sig[0]))
{
Fail(size + "bit"
+ ": r component wrong." + SimpleTest.NewLine
+ " expecting: " + r + SimpleTest.NewLine
+ " got : " + sig[0]);
}
if (!s.Equals(sig[1]))
