Method Detail

getAlgOID

public static void getAlgOID(byte[] algorithm,
                             byte[] oid,
                             int oidSize)
                      throws NativeException

Get algorithm OID "Object identifier".

Parameters:

algorithm - algorithm name, null terminated `\0`

oid - byte array containing a string representation of the Object identifier

oidSize - the size of oid array

Throws:

NativeException - on error

implSign

protected byte[] implSign(byte[] digestValue)

Specified by:

implSign in class AbstractSignatureSpi

implVerify

protected boolean implVerify(byte[] sigBytes,
                             byte[] digestValue)

Specified by:

implVerify in class AbstractSignatureSpi

nativeGetAlgorithmDescription

public static int nativeGetAlgorithmDescription(byte[] algorithm,
                                                byte[] digestAlgorithmName,
                                                int digestAlgorithmNameLength)

Gets for the given algorithm the signature algorithm description.

Parameters:

algorithm - Null terminated string that describes the algorithm

digestAlgorithmName - (output param) Null terminated string that describes the digest algorithm.

digestAlgorithmNameLength - (output param) Length of digest_algorithm.

Returns:

algorithm ID on success or -1 on error.

setKeys

protected void setKeys(PublicKey publicKey,
                       PrivateKey privateKey)
                throws InvalidKeyException

Description copied from class: AbstractSignatureSpi

Sets the public and private keys for this signature.

Specified by:

setKeys in class AbstractSignatureSpi

Parameters:

publicKey - the public key to set

privateKey - the private key to set

Throws:

InvalidKeyException - if one of the keys is invalid.
