[Source code and documentation sharing] DES encryption algorithm is based on Python implementation

First, the algorithm description

DES algorithm is a data block in units of 64 bits using encryption and decryption of 56 + 8 = 64 parity bits key. It is implemented encryption and after decryption to generate a first encryption key, the user enters a password 64 bits long, then aliquoted, shift, select, and a 16 iteration formed encryption keys, respectively, for each round operation.
