Method Detail

getCertificateChain

public byte[][] getCertificateChain(java.lang.String keyCAR)

Description copied from interface: TerminalAuthenticationSigner

Return a list of Card Verifiable Certificates, starting with the certificate that can verified by the public key referenced in parameter keyCAR and ending with the certificate that is issued to the terminal authentication signer in use.

Specified by:

getCertificateChain in interface TerminalAuthenticationSigner

Parameters:

keyCAR - the Certificate Holder Reference (CAR) of the public key in the card that can be directly used to verify a certificate. This is typically a root or link certificate or a DVCA certificate that was already verified by the card.

Returns:

the list of CVCs.

getTASignature

public byte[] getTASignature(byte[] dataTBS,
                             java.lang.String keyCHR)

Description copied from interface: TerminalAuthenticationSigner

Calculate a signature over the data to be signed using the terminal authentication key identified by keyCHR. The signature must be return in a format suitable for presentation to the card, i.e. in R|S format for ECDSA. The hash algorithm is determined by the terminal authentication signer.

Specified by:

getTASignature in interface TerminalAuthenticationSigner

Parameters:

dataTBS - the input for the hash and the signature operation

keyCHR - the terminal authentication key

Returns:

the signature
