What is the difference between Symmetric and Asymmetric encryption?
Basis of Comparison | Symmetric Encryption | Asymmetric Encryption |
|---|---|---|
| Encryption key | Same key for encryption & decryption | Different keys for encryption & decryption |
| Performance | Encryption is fast but more vulnerable | Encryption is slow due to high computation |
| Algorithms | DES, 3DES, AES and RC4 | Diffie-Hellman, RSA |
| Purpose | Used for bulk data transmission | Often used for securely exchanging secret keys |
