This is an implementation of all famous cryptography algorithms in python. There are several algorithm of cipher in this like Caesar, Transposition, Substitution, Vigenere, AES and RSA

A few projects, done as part of the course work for Network Security, IIIT-D.

Security Package is a package that includes several security modules - Ciphers, Image Encryption and Decryption, Audio Encryption and Decryption, Steganography, Background Removal, OTP Generation and Authentication.

A Python implementation of the classical Rail Fence cipher with encryption and decryption support. Built for educational purposes to understand zigzag-based transposition and historical cryptographic techniques.

A Python implementation of the classical Row-Column Transposition cipher with encryption and decryption support. Built for educational purposes to understand column permutation and historical transposition-based cryptographic techniques.

A Python implementation of brute-force cryptanalysis for the Rail Fence Cipher. This project systematically tests all possible rail values to demonstrate structural weaknesses in classical transposition-based cryptographic systems.
