Episode 17 — Symmetric vs. Asymmetric Encryption (1.3)
This episode compares symmetric and asymmetric encryption by focusing on how each method is used in practical security designs. Symmetric encryption uses the same secret key to encrypt and decrypt data, making it fast and useful for files, disks, databases, and bulk traffic protection. Asymmetric encryption uses a public key and private key pair, making it useful for trust, secure key exchange, authentication, and digital signatures. For Security+ scenarios, students should understand that modern protocols often combine both approaches, using asymmetric methods to establish trust and exchange keys, then symmetric encryption to protect the actual session data efficiently.
