sdes-go

Implementation of a simplified Data Encryption Standard (DES) in GO

Usage:

Ecrypt:

go run sdes.go '8-bit plain text' '10-bit key'

Example: go run sdes.go 11100101 1011001010

Decrypt (add 'd' flag):

go run sdes.go '8 bit encrypted text' '10 bit key' d

Example: go run sdes.go 11011111 1011110111 d

TO-DO

• Implement Cipher Block Chaining (CBC) system
• Translate variable names
• Add code comments
• Search about the possibility of padding the plain text entry
