Text & file encrypter and decrypter using a variety of algorithms

A simple, commented and readable python implementation of ChaCha, Salsa, Poly1305, MD2, MD4, MD5, SHA1, SHA2, SHA3, Blake, Blake2, DES, 3DES, and more

A Python script that includes various functions for data conversion, encoding, and decoding, as well as cryptographic operations such as RSA, AES, and Triple DES encryption and decryption.

Compiler-free Python crypto library backed by the OS, supporting CPython and PyPy

Using 3DES algorithm and Steganography(LSB) for hiding encrypted message inside image

CLI application for encrypting and decrypting files using triple DES

Implementation of various symmetric key encryption systems like AES, DES, triple DES (3 DES), Ceasar cipher, Substitution cipher, Hill cipher

A 3DES implementation in Python.

Implementation of an End to end encrypted messaging system, where client to client communication is performed after triple-DES encryption, with the keys exchanged using Diffie-Hellman Key exchange algorithm. A user is also able to create multiple groups and be a part of any set of groups. Messages could be text, images, video file etc.

P2P Messaging System with End to End encryption. Supports group chat and file transfer

Implemented a chat application with end to end encryption with file sharing and group chat functionalities.

An end to end messaging system like WhatsApp.

P2P Messaging System with End to End encryption

Suppose there are n c users A (clients) want to securely access the files stored in the database of a user B (server). At first, each client will make a connection using socket with the server B and then will establish three symmetric keys, say K 1 , K 2 and K 3 which will be used for encryption and decryption using the 3DES with three keys symm…
