For the first time in India, the Data Security Council of India (DSCI) has recognised a domestically built quantum-safe ...

This project implements two cryptographic algorithms: RC4, a stream cipher, and AES (Advanced Encryption Standard), a block cipher. Both algorithms are widely used in cryptography for their unique ...

The Data Encryption Standard (DES) is a symmetric-key algorithm for the encryption of digital data. It uses a fixed-size key and operates on blocks of data, making it a fundamental concept in the ...

Quantum computing, AI-powered attacks, and post-quantum standardization have fundamentally shifted the encryption landscape. This guide covers every major algorithm class and what the 2024 NIST ...
