SignatureProcessorFactory (JavaDocs for mmm-all 1.0.0-SNAPSHOT)

Type Parameters:

S - type of SignatureBinary.

PR - type of PrivateKey.

PU - type of PublicKey.

All Superinterfaces:

SignatureFactory<S>

All Known Implementing Classes:

AsymmetricAccess, AsymmetricAccessEcBc, Curve25519, Rsa, Secp256k1, SignatureProcessorFactoryImpl, SignatureProcessorFactoryImplCryptorWithHash, SignatureProcessorFactoryImplEcBc, 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.

Since:

1.0.0

- 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).
