generateSignature

public void generateSignature(java.lang.String username,
                              java.lang.String password,
                              byte[] dataToSign,

                              byte[] debitAmount,
                              int signatureType,
                              byte[] signature,
                              byte[] certificate,

                              int[] retLengths)
                       throws PBException

Specified by:

generateSignature in interface IPB

Parameters:

username - PSD username

password - PSD password

dataToSign - the data the PSD is to sign

dataToSignLength - how much of dataToSign we wish to sign

dataRequest - TODO: 4 byte array for?

debitAmount - TODO: 4 byte array for debit amount, but what units

signatureType - TODO: meaning?

signature - returned signature

certificate - returned certificate

signedData - returned signed data

retLengths - lengths: signature, certificate, data as [0], [1], [2] TODO: ditch retLengths since it is very ugly, but keep ability to let caller predefine the memory; would have used streams if I could have figured out how to get them into JNI-land.

Throws:

PBException

isSignatureValid

public boolean isSignatureValid(java.lang.String username,
                                java.lang.String password,
                                byte[] data,
                                int dataLength,
                                byte[] signature,
                                int signatureLength,
                                int signatureType)
                         throws PBException

Description copied from interface: IPB

Verify a signature.

Specified by:

isSignatureValid in interface IPB

Parameters:

username - PSD username

password - PSD password

data - array containing the signed data

dataLength - length of the data

signature - signature from a previous call to generateSignature

signatureLength - length of the signature

signatureType - TODO - not sure what valid values are

Returns:

true if signature was verified, and hence is valid, false otherwise

Throws:

PBException
