A Django project on implementing Digital Signature using RSA algorithm, users can upload their files and view them, lastly sign them digitally and let others verify their identity with ease

A cryptography package with simplifed versions of AES and SHA-1, RSA, HMAC; featuring attacks, block ciphers and digital signature schemes.

Group Chat. 2 Projects: Server + Client which implements Tree-based Group Diffie-Hellman protocol to calculate and distribute group key. The key is used to encrypt and decrypt data using AES cipher. Moreover signalling messages between server and client are also digital signatured using SHA1 with RSA.

BlockChain Constructed using Python Flask, with RSA Algorithm and Digital Signatures

This project uses RSA encryption algorithm with the BigInteger library and SHA256 function to create digital signatures for files.

A windows form application where you can create your own certificate (.cer), extract the private and public keys to a .pem file, sign a digital signature and check the accuracy of this signature, encrypt and decrypt the data with these private and public keys with asymmetric encryption (RSA).

This is an encryptiona and decryption group chat project. In the project AES,DES,Multiplicative_ceaser, RSA, Elgamal, RSA and Digital Signature are used and has a graphic interface with tkinter, database for signing in and in the background of database Hash function SHA512 is used for Authentication.

Crypto Transfer (Simulated) is a hands-on learning web application built with PHP and JavaScript, simulating secure cryptocurrency transactions using RSA digital signatures. It mimics real-world crypto systems with added wallet and transaction features for a more practical understanding.

This project is designed to ensure the confidentiality and integrity of data transmitted between clients and servers. The system utilizes the RSA encryption algorithm for secure secret key encryption and digital signature, along with an AES variant for efficient ciphertext decryption.

“Naber’la” is a chatting application using end to end encryption of messages. A simple console application in java which uses AES and RSA to ensure confidentiality and integrity of messages besides ensuring the authenticity with Digital Signature. Application primary goal is transferring encrypted messages between terminals as users.
