Throws:

SignatureException

updateEngine

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

Specified by:

engineUpdate in class SignatureSpi

Throws:

SignatureException

updateEngine

protected abstract void updateEngine(byte[] buf,
 int off,
 int len)
                              throws SignatureException

Throws:

SignatureException

engineSetParameter

protected void engineSetParameter(AlgorithmParameterSpec params)
                           throws InvalidAlgorithmParameterException

Set the signature context, either before or after engineInitSign / engineInitVerify.

Where the signature has a key already the underlying signer is re-initialised with the new context at once; where it does not the context is recorded and applied when the key arrives, as the RSASSA-PSS implementation does with its own parameters. Calling this first used to let a NullPointerException out of a method declared to throw InvalidAlgorithmParameterException, from dereferencing the key that was not there yet (see github #2396).

Overrides:

engineSetParameter in class SignatureSpi

Throws:

InvalidAlgorithmParameterException
