public byte[] sign(SessionContext session)
            throws Exception
```
    Description copied from interface: Signature
    
    Compute the signature
    
    Specified by:
    
    sign in interface Signature
    
    Overrides:
    
    sign in class AbstractSignature
    
    Parameters:
    
    session - The SessionContext for calling this method - may be null if not called within a session context
    
    Returns:
    
    The signature value
    
    Throws:
    
    Exception - If failed to calculate the signature
  - verify
```
public boolean verify(SessionContext session,
                      byte[] sig)
               throws Exception
```
    Description copied from interface: Signature
    
    Verify against the given signature
    
    Parameters:
    
    session - The SessionContext for calling this method - may be null if not called within a session context
    
    sig - The signed data
    
    Returns:
    
    true if signature is valid
    
    Throws:
    
    Exception - If failed to extract signed data for validation
