Symmetric vs Asymmetric Encryption Explained 🔐 | Cybersecurity Basics

Symmetric vs Asymmetric Encryption 1. Key Usage Symmetric: One key for encryption & decryption. Asymmetric: Two keys - public () & private(). 2. Speed Symmetric: Faster & efficient for large data. Asymmetric: Slower but more secure for small data. 3. Security Symmetric: Vulnerable if the key is exposed. Asymmetric: More secure due to separate keys. 4. Use Cases Symmetric: File encryption, secure backups. Asymmetric: Digital signatures, secure key exchange. 5. Examples Symmetric: AES, DES. Asymmetric: RSA, ECC. Summary: Symmetric encryption is faster for bulk data, while asymmetric is ideal for secure communication and key exchange. Use them together for optimal security!
