Method Detail

engineSignback to summary
protected byte[] engineSign() throws SignatureException

Implements abstract java.security.SignatureSpi.engineSign.

Doc from java.security.SignatureSpi.engineSign.

Returns the signature bytes of all the data updated so far. The format of the signature depends on the underlying signature scheme.

Returns:byte[]

the signature bytes of the signing operation's result.

Exceptions
SignatureException:
if the engine is not initialized properly or if this signature algorithm is unable to process the input data provided.
engineVerifyback to summary
protected boolean engineVerify(byte[] sigBytes) throws SignatureException

Implements abstract java.security.SignatureSpi.engineVerify.

Doc from java.security.SignatureSpi.engineVerify.

Verifies the passed-in signature.

Parameters
sigBytes:byte[]

the signature bytes to be verified.

Returns:boolean

true if the signature was verified, false if not.

Exceptions
SignatureException:
if the engine is not initialized properly, the passed-in signature is improperly encoded or of the wrong type, if this signature algorithm is unable to process the input data provided, etc.
