Method Detail

engineSetParameter

protected final void engineSetParameter(AlgorithmParameterSpec params)
                                 throws InvalidAlgorithmParameterException

ECDSA is not supported in Gemini product.

Overrides:

engineSetParameter in class SignatureSpi

Following copied from class: com.motorola.iden.security.SignatureSpi

Parameters:

params - the parameters

Throws:

java.lang.SecurityException - if this method is not overridden by a provider

InvalidAlgorithmParameterException - if this method is overridden by a provider and the the given parameters are inappropriate for this signature engine

engineGetParameter

protected final AlgorithmParameterSpec engineGetParameter()

ECDSA is not supported in Gemini product.

Overrides:

engineGetParameter in class SignatureSpi

Following copied from class: com.motorola.iden.security.SignatureSpi

Returns:

the parameters used with this signature engine, or null if this signature engine does not use any parameters

Throws:

java.lang.SecurityException - if this method is not overridden by a provider

engineInitSign

protected final void engineInitSign(PrivateKey Key)
                             throws InvalidKeyException

ECDSA is not supported in Gemini product.

Overrides:

engineInitSign in class SignatureSpi

Following copied from class: com.motorola.iden.security.SignatureSpi

Parameters:

privateKey - the private key of the identity whose signature will be generated.

Throws:

InvalidKeyException - if the key is improperly encoded, parameters are missing, and so on.

engineInitVerify

protected final void engineInitVerify(PublicKey Key)
                               throws InvalidKeyException

ECDSA is not supported in Gemini product.

Overrides:

engineInitVerify in class SignatureSpi

Following copied from class: com.motorola.iden.security.SignatureSpi

Parameters:

publicKey - the public key of the identity whose signature is going to be verified.

Throws:

InvalidKeyException - if the key is improperly encoded, parameters are missing, and so on.

engineUpdate

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

ECDSA is not supported in Gemini product.

Overrides:

engineUpdate in class SignatureSpi

Following copied from class: com.motorola.iden.security.SignatureSpi

Parameters:

b - the array of bytes

off - the offset to start from in the array of bytes

len - the number of bytes to use, starting at offset

Throws:

SignatureException - if the engine is not initialized properly

engineSign

protected final byte[] engineSign()
                           throws SignatureException

ECDSA is not supported in Gemini product.

Overrides:

engineSign in class SignatureSpi

Following copied from class: com.motorola.iden.security.SignatureSpi

Returns:

the signature bytes of the signing operation's result.

Throws:

SignatureException - if the engine is not initialized properly.

engineVerify

protected final boolean engineVerify(byte[] sigBytes)
                              throws SignatureException

ECDSA is not supported in Gemini product.

Overrides:

engineVerify in class SignatureSpi

Following copied from class: com.motorola.iden.security.SignatureSpi

Parameters:

sigBytes - the signature bytes to be verified.

input - message to be verified.

Returns:

true if the signature was verified, false if not.

Throws:

SignatureException - if the engine is not initialized properly, or the passed-in signature is improperly encoded or of the wrong type, etc.
