A side project developed for Experiment 2 of Security Lab, Design & implementation of a product cipher using substitution and transposition Ciphers. The link to the website is given below. Have fun!

A basic cryptographic algorithm 🔐 using combination of substitution & transposition ciphers.

Codes written during course 'Cryptography and System Security'

Proof-of-concept Product Cipher using cryptography classics (CS3052 Computer Security - Assignment)

Implementation of an SP Network using a new modified Playfair Cipher for substitution and the chaotic Logistic-Tent Map for permutation, in Python. This new algorithm has been named Playfair Logistic-Tent Network (PLT-Net).

This project about a simple product cipher using Java language without using any library routines.
