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

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.

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

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

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…
