In this article, you'll learn how to build a secure and efficient backend API in Rust with JWT access and refresh tokens functionality. We'll leverage the high-performance Axum framework and SQLX to store data in a PostgreSQL database.

Cryptography Notebook is a repository containing some of the cryptographic implementations I have done for learning purposes.

A simple Java application for encrypting and decrypting messages and files using DES and RSA algorithms, featuring a user-friendly menu interface. Perfect for learning about cryptography and secure file handling.

A small Node.js/TypeScript project showing how to encrypt off‑chain data for on‑chain storage using X25519 + authenticated encryption.

Advanced Encryption Standard (AES)

Simple explanation on the symmetric encryption problematics and main idea behind the Rivest-Shamir-Adleman (RSA) encryption.

An end to end encrypted chat app built using React, Express, Socket.io, Mongodb, Node.Js, LDAP & OpenSSL

Easy one line function calls for AES Encryption, SHA hashes, MD5 hashes, key generation and other utilities.

A novel post-quantum cryptographic library that combines three heterogeneous hard problems with cryptographic entanglement for defense-in-depth security.

A Stateless, Client-Side, Privacy-First Encryption App with Zero Servers, Zero Remote Network Requests, Zero Telemetry, Zero Dependencies, Zero Backend, Zero Install, Zero Data Out, Symmetric Encryption, Asymmetric Encryption, Plausible Deniability and Decoy Generation

This project is about understanding and using different encryption algorithm

Helper to encrypt / decrypt files from openssl

This project focuses on cloud data security by designing an optimized key generation scheme for data protection and a deep learning model for user attack detection. The data protection scheme encrypts data before uploading it to the cloud, while the attack detection module uses a deep learning model to identify malicious users

The repository contains a set of classes on Dart for implementing a hybrid message encryption method.

Encrypting and Decrypting the key of a symmetric cipher (Keyword Cipher) with the help of RSA.
