initSign

public void initSign(PrivateKey privateKey)
              throws java.security.InvalidKeyException,
                     TokenException
Deprecated. 
Initialize the signature context for signing.

Parameters:
privateKey - The private key with which to sign.
Throws:
java.security.InvalidKeyException - If the key is the wrong type for the algorithm or does not exist on the token of this signature context.
TokenException - If an error occurred on the token.

initVerify

public void initVerify(java.security.PublicKey publicKey)

Deprecated. 
Initialize the signature context for verifying.

Parameters:
publicKey - The public key with which to verify the signature.
Throws:
java.security.InvalidKeyException - If the key is the wrong type for the algorithm.
TokenException - If an error occurs on the token.

                  throws java.security.InvalidAlgorithmParameterException,
                         TokenException
Deprecated. 
Set parameters for the signing algorithm. This is currently not supported or needed.

Parameters:
params - Parameters for the signing algorithm.
Throws:
java.security.InvalidAlgorithmParameterException - If there is something wrong with the parameters.
TokenException - If an error occurs on the token.
