Understanding Core Cryptographic Technologies: A Deep Dive for Experts
Modern digital security relies on robust cryptographic systems. In this article, we break down symmetric encryption, asymmetric encryption, hash functions, and critical algorithms—with a focus on technical specifications and real-world applications. 🔑 Symmetric Encryption (Secret-Key Cryptography) Single key for encryption/decryption 🗝️. Ideal for high-speed bulk data processing. 🚀 Key Algorithms Algorithm Type Specs & Use Cases DES Block 56-bit key ⚠️ (Used in LM Hash) 3DES Block Triple-DES; 128-bit key RC4 Stream ⚠️ Deprecated (WEP’s fatal flaw) AES Block ⭐ Gold standard (WPA2, NSA-approved) 🌐 Asymmetric Encryption (Public-Key Cryptography) Key pairs (public/private) 🔑🔒. Critical for PKI, TLS, and digital signatures. ...
