All Implemented Interfaces:

DataStructure

public class Signature
extends SimpleDataStructure

Defines the signature as defined by the I2P data structure spec. A signature is a 40-byte array verifying the authenticity of some data using the DSA-SHA1 algorithm. The signature is the 20-byte R followed by the 20-byte S, both are unsigned integers.
