Symmetric vs. Asymmetric Encryption: A Clear Comparison
Key Points:
- Symmetric encryption uses the same key for both encryption and decryption.
- Asymmetric encryption uses two separate keys: a public key for encryption and a private key for decryption.
- The primary difference lies in key management and speed; symmetric is faster but requires secure key exchange, while asymmetric is slower but offers better key management.
**Symmetric vs. Asymmetric Encryption: A Detailed Breakdown**
| Feature | Symmetric Encryption | Asymmetric Encryption |
|---|---|---|
| Key Type | Single secret key | Public and private key pair |
| Speed | Fast | Slow |
| Key Exchange | Requires secure channel | Public key can be openly shared |
| Key Management | Complex, secure key distribution crucial | Simpler, public key easily distributed |
| Digital Signatures | Not directly supported | Supported using private key |
