Method Detail

serialize

public static Signature serialize(ECDSASignature signature,
                                  java.math.BigInteger order)

Serialize ecdsa signature.

Parameters:

signature - a ecdsa signature

order - an order of the sign key

Returns:

                                   java.math.BigInteger order)

Parse ECDSASignature from the serialized one.

Parameters:

signature - an signature

order - an order of signature key

Returns:

parsed ECDSASignature. null if parsing failed.
