📌 Overview

Cryptographic algorithms are the backbone of secure communication. They ensure data confidentiality, integrity, and authentication. This guide explores key categories:

  • Symmetric Encryption
    Uses a single key for encryption/decryption.
    🔑 Example: AES (Advanced Encryption Standard)

    AES

  • Asymmetric Encryption
    Employs a public/private key pair.
    📩 Example: RSA (Rivest-Shamir-Adleman)

    RSA

  • Hash Functions
    Converts data into a fixed-size hash.
    🧾 Example: SHA-256 (Secure Hash Algorithm)

    SHA_256
