    Returns the value of the parameter with the specified name.

    Specified by:

    engineGetParameter in class SignatureSpi

    Parameters:

    param - the name of the requested parameter value.

    Returns:

    the value of the parameter with the specified name, maybe null.

    Throws:

    InvalidParameterException - if param is not a valid parameter for this SignatureSpi or an other error occurs.

  • engineInitSign

    protected void engineInitSign(PrivateKey privateKey)
                           throws InvalidKeyException

    Description copied from class: SignatureSpi
    Initializes this SignatureSpi instance for signing, using the private key of the identity whose signature is going to be generated.

    Specified by:

    engineInitSign in class SignatureSpi

    Parameters:

    privateKey - the private key.

    Throws:

    InvalidKeyException - if privateKey is not valid.

  • engineInitVerify

    protected void engineInitVerify(PublicKey publicKey)
                             throws InvalidKeyException

    Description copied from class: SignatureSpi
    Initializes this SignatureSpi instance for signature verification, using the public key of the identity whose signature is going to be verified.

    Specified by:

    engineInitVerify in class SignatureSpi

    Parameters:

    publicKey - the public key.

    Throws:

    InvalidKeyException - if publicKey is not valid.

  • engineSetParameter

    protected void engineSetParameter(String param,
                          Object value)
                               throws InvalidParameterException

    Description copied from class: SignatureSpi
    Sets the specified parameter to the given value.

    Specified by:

    engineSetParameter in class SignatureSpi

    Parameters:

    param - the name of the parameter.

    value - the parameter value.

    Throws:

    InvalidParameterException - if the parameter is invalid, already set or is not allowed to be changed.

  • engineSign

    protected byte[] engineSign()
                         throws SignatureException

    Description copied from class: SignatureSpi
    Generates and returns the signature of all updated data.

    This SignatureSpi instance is reset to the state of its last initialization for signing and thus can be used for another signature from the same identity.

    Specified by:

    engineSign in class SignatureSpi

    Returns:

    the signature of all updated data.

    Throws:

    SignatureException - if this SignatureSpi instance is not initialized properly.

  • engineUpdate

    protected void engineUpdate(byte b)
                         throws SignatureException

    Description copied from class: SignatureSpi
    Updates the data to be verified or to be signed, using the specified byte.

    Specified by:

    engineUpdate in class SignatureSpi

    Parameters:

    b - the byte to update with.

    Throws:

    SignatureException - if this SignatureSpi instance is not initialized properly.

  • engineUpdate

    protected void engineUpdate(byte[] b,
                    int off,
                    int len)
                         throws SignatureException

    Description copied from class: SignatureSpi
    Updates the data to be verified or to be signed, using the given byte[], starting form the specified index for the specified length.

    Specified by:

    engineUpdate in class SignatureSpi

    Parameters:

    b - the byte array to update with.

    off - the start index in b of the data.

    len - the number of bytes to use.

    Throws:

    SignatureException - if this SignatureSpi instance is not initialized properly.

  • engineVerify

    protected boolean engineVerify(byte[] sigBytes)
                            throws SignatureException

    Description copied from class: SignatureSpi
    Indicates whether the given sigBytes can be verified using the public key or a certificate of the signer.

    This SignatureSpi instance is reset to the state of its last initialization for verifying and thus can be used to verify another signature of the same signer.

    Specified by:

    engineVerify in class SignatureSpi

    Parameters:

    sigBytes - the signature to verify.

    Returns:

    true if the signature was verified, false otherwise.

    Throws:

    SignatureException - if this SignatureSpi instance is not initialized properly.

  • engineSetParameter

    protected void engineSetParameter(AlgorithmParameterSpec params)
                               throws InvalidAlgorithmParameterException

    Description copied from class: SignatureSpi
    Sets the specified AlgorithmParameterSpec.

    Overrides:

    engineSetParameter in class SignatureSpi

    Parameters:

    params - the parameter to set.

    Throws:
