Cryptography

This repo conatins implementation of cryptography concepts in C. This repo might be helpful for all the developers who wants to learn not only the algorithm but also the bit by bit implementation of it.

Table of contents:

1. Data Encryption Standard (DES)

2. Random number generation

• LFSR implementation in C

• Insecure random number generation in Java

• Secure random number generation in Java

• Generate random bits in C

3. Stream cipher

4. Hashing

• MD5

NOTE : All algorithms and concepts implemented are for understanding purpose only. In case of production environment, use trusted crypto libraries like OpenSSL.
