  - getAlgorithm
```
public String getAlgorithm()
```
    Specified by:
    
    getAlgorithm in interface CryptoAlgorithm
    
    Returns:
    
    the name of the underlying algorithm (e.g. "RSA", "NONEwithECDSA", etc.).

    Key.getAlgorithm(), Signature.getAlgorithm(), MessageDigest.getAlgorithm(), SecureRandom.getAlgorithm(), Cipher.getAlgorithm()
  - newSigner
```
public SignatureSigner<S> newSigner(PR privateKey)
```
    Specified by:
    
    newSigner in interface SignatureProcessorFactory<S extends SignatureBinary,PR extends PrivateKey,PU extends PublicKey>
    
    Parameters:
    
    privateKey - the PrivateKey to use for signing.
    
    Returns:
    
    the SignatureSigner for signing.
  - newVerifier
```
public SignatureVerifier<S> newVerifier(PU publicKey)
```
    Specified by:
    
    newVerifier in interface SignatureProcessorFactory<S extends SignatureBinary,PR extends PrivateKey,PU extends PublicKey>
    
    Parameters:
    
    publicKey - the PublicKey to use for verifying.
    
    Returns:
    
    the SignatureVerifier for verifying.
  - createSignature
```
public S createSignature(byte[] data)
```
    Specified by:
    
    createSignature in interface SignatureFactory<S extends SignatureBinary>
    
    Parameters:
    
    data - the binary signature data.
    
    Returns:
    
    the deserialized SignatureBinary.
  - getSignatureFactoryWithoutHash
```
public SignatureProcessorFactory<S,PR,PU> getSignatureFactoryWithoutHash()
```
    Specified by:
    
    getSignatureFactoryWithoutHash in interface SignatureProcessorFactory<S extends SignatureBinary,PR extends PrivateKey,PU extends PublicKey>
    
    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).
