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!
