All Implemented Interfaces:

CryptoAlgorithm
```
public final class SignatureAlgorithm
extends Object
implements CryptoAlgorithm
```
Little helper to workaround quirks in JCE/JCA for signature algorithm names.

Since:

1.0.0

  - getAlgorithm
```
public String getAlgorithm()
```
    Specified by:
    
    getAlgorithm in interface CryptoAlgorithm
