Examples
// Sign data
ECDsaSignature signer = new ECDsaSignature();

// A private key is needed to sign data
signer.CreateKeyPair();

byte[] data = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9};
byte[] signature = signer.SignData(data);

// To verify that the signature data we need only the public key
ECDsaSignature verifier = ECDsaSignature.FromKeys(signer.PublicKey);

// Returns true
bool result = verifier.VerifyData(data, signature);
