Interface SignatureProcessorFactory<S extends SignatureBinary,PR extends PrivateKey,PU extends PublicKey>

Type Parameters:

S - type of SignatureBinary.

PR - type of PrivateKey.

PU - type of PublicKey.

All Superinterfaces:

SignatureFactory<S>

All Known Implementing Classes:

AsymmetricAccess, Rsa, SignatureProcessorFactoryImpl, SignatureProcessorFactoryImplCryptorWithHash, SignatureProcessorFactoryImplWithHash

public interface SignatureProcessorFactory<S extends SignatureBinary,PR extends PrivateKey,PU extends PublicKey>
extends SignatureFactory<S>

Interface for a factory to create instances of SignatureProcessor for asymmetric cryptography. Signatures only work with asymmetric security. For a given private key a SignatureSigner can be created that allows to sign any message. With the corresponding public key anyone can create a SignatureVerifier to verify the SignatureBinary.
An instance of SignatureProcessorFactory typically combines asymmetric cryptography with hashing.

Method Detail

newSignerUnsafe

default SignatureSigner<S> newSignerUnsafe(PrivateKey privateKey)

Parameters:

privateKey - the PrivateKey to use for signing.

Returns:

the SignatureSigner for signing.

newSigner

SignatureSigner<S> newSigner(PR privateKey)

Parameters:

privateKey - the PrivateKey to use for signing.

Returns:

the SignatureSigner for signing.

newVerifierUnsafe

default SignatureVerifier<S> newVerifierUnsafe(PublicKey publicKey)

Parameters:

publicKey - the PublicKey to use for verifying.

Returns:

the SignatureVerifier for verifying.

newVerifier

SignatureVerifier<S> newVerifier(PU publicKey)

Parameters:

publicKey - the PublicKey to use for verifying.

Returns:

the SignatureVerifier for verifying.

getSignatureFactoryWithoutHash

SignatureProcessorFactory<S,PR,PU> getSignatureFactoryWithoutHash()

Returns:

an instance of this SignatureFactory that does not hash before signing so you can control the hashing manually and only sign the resulting hash (e.g. to reuse the hash value for further calculations).
