Python program to encrypt/decrypt ciphers from .txt files or manually-typed strings.
A simple CLI & GUI Vigenere cipher tool. This tool will encrypt and decrypt text using the Vigenere cipher method. Its more secure than Caesar or ROT13.
Ransomware that encrypts and decrypts .txt, .py, .docx and .pdf in specified directories with a modified Vigenère cipher.
This repository contains encryption tool. This tool uses vigenere cipher with user-defined keys. This repository is intended for academic purposes only and should not be used for any malicious activities. See demo at:
Suite of cryptographic tools that provides encryption, decryption, and cipher-breaking functionalities using classical algorithms such as the Caesar Cipher and Vigenère Cipher.
In this repository, we introduce the index of coincidence and its use in the cryptanalysis of polyalphabetic ciphers, in particular, Vigenère cipher.
