Triple Des Key Generator C

Posted on by

This is an implementation in C of DES (Data Encryption Standard).

It does not work correctly, see https://github.com/mimoo/DES/issues/6 Ms 2010 product key generator.

Imports System.Security.Cryptography Imports System.Text Imports System.IO Module TripleDESSample Sub Main Try ' Create a new TripleDES object to generate a key ' and initialization vector (IV). Specify one ' of the recognized simple names for this ' algorithm. The Triple Data Encryption Standard (DES) is a symmetric key encryption algorithm for computerized cryptography. As per the algorithm, the same key is used for encryption and decryption. Also, the same block cipher algorithms are applied three times to each data block.

  • The Triple DES Coprocessor is a Data Encryption Standard (FIPS 46-3) peripheral computing DES or TDES encryption and decryption through a highly-optimized secure architecture. Based on 2.5 kgates, the Triple DES Coprocessor computes DES and TDES in 16 and 48 cycles respectively.

  • I Annex A: Approved Security Functions for FIPS PUB 140-2, Security Requirements for Cryptographic Modules 1. Introduction Federal Information Processing Standards Publication (FIPS) 140-2, Security Requirements for Cryptographic Modules, specifies the security requirements that are to be satisfied by the cryptographic module utilized within a security system protecting sensitive information.

This is to be used only for files that are multiples of 64 bits exactly. We used ECB as a mode of operation but haven't implemented any padding system (it is not the point, if you want to add it you can always fork the code!).

DES is a broken cypher and this work is intended for educational purpose.

Files

  • DES.c and DES.h contain the functions used in the DES algorithm.

  • main.c builds the algorithm and allows you to encrypt/decrypt an input file.

Use make to build desbox.

  • genkey.c is a key generator that prevents weak keys. Use it if you don't have any key to use.

Use make to build the keygen.
