Interface Signer
- SignerWithRecovery
- ISO9796d2PSSSigner, ISO9796d2Signer, PSSSigner, RSADigestSigner
Generic signer interface for hash based and message recovery signers.
byte[] | generateSignature() - generate a signature for the message we've been loaded with using
the key we were initialised with.
|
void | init(boolean forSigning, CipherParameters param) - Initialise the signer for signing or verification.
|
void | reset() - reset the internal state
|
void | update(byte b) - update the internal digest with the byte b
|
void | update(byte[] in, int off, int len) - update the internal digest with the byte array in
|
boolean | verifySignature(byte[] signature) - return true if the internal state represents the signature described
in the passed in array.

forSigning
- true if for signing, false otherwiseparam
- necessary parameters.
