- Method Detail
  - getKeyIdentity

KeyPair getKeyIdentity()
```
    Returns:
    
    The KeyPair identity value
  - sign
```
Map.Entry<String,byte[]> sign(SessionContext session,
                                    String algo,
                                    byte[] data)
                             throws Exception
```
    Proves the public key identity by signing the given data
    
    Parameters:
    
    session - The SessionContext for calling this method - may be null if not called within a session context
    
    algo - Recommended signature algorithm - if null/empty then one will be selected based on the key type and/or signature factories. Note: even if specific algorithm specified, the implementation may disregard and choose another
    
    data - Data to sign
    
    Returns:
    
    used algorithm + signed data - using the identity
    
    Throws:
    
    Exception - If failed to sign the data
