Method Detail

checkSignature

public boolean checkSignature(byte[] Value,
                              byte[] Signature,
                              java.lang.String algorithmID,
                              TokenLocator Signer)
                       throws PkiException

This method checks if the Signature for the given Value has been signed by the Signer. This is the default implementation. The method does not really check the signature but only check if the Value is an empty value or not. It returns true for all non-empty value.

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 Principal of the signer

Returns:

true, if the Value is not null and the Value contains an arrange with the length greater than 0; false otherwise

Throws:

PkiException - if any unrecoverable error occurs
