- Method Detail
  - perform
```
byte[] perform(byte[] blob)
        throws TokenStrategyFailedException
```
    Perform the operation on the Token. This operation is expected to modify the Token in some way which will require reversing in the opposite direction.
    
    Parameters:
    
    blob - Non null Token data to modify.
    
    Throws:
    
    TokenStrategyFailedException - If an error occurred whilst processing the Token.
  - reverse
```
byte[] reverse(byte[] blob)
        throws TokenStrategyFailedException
```
    Reverse the operation on the Token. This operation is expected to modify the Token in some way which can be reversed by performing it again.
    
    Parameters:
    
    blob - Non null Token data to modify.
    
    Throws:
    
    TokenStrategyFailedException - If an error occurred whilst processing the Token.
