This is a pure python implementation of the DES encryption algorithm.
|
||
|
|
It is in pure python to avoid portability issues, since most DES
|
||
|
|
implementations are programmed in C (for performance reasons).
|
||
|
|
|
||
|
|
Triple DES class is also implemented, utilising the DES base. Triple DES
|
||
|
|
is either DES-EDE3 with a 24 byte key, or DES-EDE2 with a 16 byte key.
|
||
|
|
See the "About triple DES" section below more info on this algorithm.
|
||
|
|
|
||
|
|
The code below is not written for speed or performance, so not for those
|
||
|
|
needing a fast des implementation, but rather a handy portable solution
|
||
|
|
ideal for small usage.
