SDDecoder keygenme by gbe32241 is a truly amazing work, worth anybody's examination.

In this knock-off, the strengthening factors are removed, namely:

- the input and output transforms are separated from the core function
- the key size is reduced from 128 bits to 64 bits
- some other minor simplifications

Here is a list of example codes.
