|
Create a new encryption object instance.
|

|
|
Decode the data. Decode the data using the algorithm embodied by the descendent class and the key specifed in the construction of the objects instance. The first form takes a string and returns a decoded string. The second form takes an encoded string and returns arbitrary binary data bytes. In both cases the encoded string is always 7 bit printable ASCII suitable for use in mail systems etc. The final form takes and arbitrary block of bytes and decodes them into another block of binary data.
