Post-Quantum Cryptography (PQC): How secure will our data be in the post-quantum era?

Hello There! As you might know, NIST has acknowledged that large-scale quantum computers will threaten the security of its approved public-key algorithms. In particular, NIST-approved digital signature schemes, key agreement using Diffie-Hellman (DH) and Menezes-Qu-Vanstone (MQV), and key agreement and key transport using Rivest–Shamir–Adleman (RSA) may need to be replaced with secure quantum-resistant (or “post-quantum”) […]

3DES algorithm : Double vs Triple Length Keys

Hello There! Just a quick introduction about what is the difference between double length and triple length in 3DES algorithm. I have created some small sample scripts written in Java to generate a 3DES key in different size of length. 1. GENERATING 3DES KEY IN TRIPLE LENGTH OF SIZE 2. GENERATING 3DES KEY IN DOUBLE […]
