Class SamplePKI

java.lang.Object
  issrg.globus.SamplePKI

All Implemented Interfaces:

SignatureVerifier

public class SamplePKI
extends java.lang.Object
implements SignatureVerifier

This PKI is a sample code. It does not do any real signature verification. It simply returns true for any signature verification request.

Method Summary

boolean

checkSignature(byte[] Value, byte[] Signature, java.lang.String algorithmID, TokenLocator Signer) This method checks if the Signature for the given Value has been created by the Signer.

checkSignature

public boolean checkSignature(byte[] Value,
                              byte[] Signature,
                              java.lang.String algorithmID,

Description copied from interface: SignatureVerifier

This method checks if the Signature for the given Value has been created by the Signer. It is the responsibility of this object to fetch any relevant CRLs, or call an OCSP server or any other method to ensure that the public key of the Signer has not been revoked. It is also the responsibility of this object to fetch the public key certificate of the signer, and to follow the certification path back to its root of trust. If the signer is not certified directly or indirectly beneath the root or roots of trust that the PKI knows about, then it must fail to verify the signature.

Specified by:

checkSignature in interface SignatureVerifier

Parameters:

Value - is the byte array that had been signed

Signature - is the byte array of the resulting signature

algorithmID - is the String representation (dotted form) of the object identifier of the algorithm used for signing

Signer - is the TokenLocator of the signer

Returns:

true, if there is a valid non-revoked PKI token, which proves the signature is valid; false otherwise
