Class HMACwithSHA1

java.lang.Object
  electric.soap.security.signature.xml.crypto.HMACwithSHA1

All Implemented Interfaces:

ISignatureAlgorithm

public class HMACwithSHA1

extends java.lang.Object

implements ISignatureAlgorithm

HMACwithSHA1 . This class is only usable with JDK 1.4 and above, since it depends on the javax.crypto.Mac class. This is not a normal public key signature, and does not provide non-repudiation evidence. Since the secret key that signed the messeage is required to verify the signature, anyone who can verify the signature can also generate new signatures.

This algorithm is identified by the URI "http://www.w3.org/2000/09/xmldsig#hmac-sha1".
