SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are both cryptographic protocols designed to provide secure communication over a network, such as HTTPS. Here’s a comparison:
| Feature | SSL | TLS |
|---|---|---|
| Full Name | Secure Sockets Layer | Transport Layer Security |
| Versions | SSL 2.0, SSL 3.0 (obsolete) | TLS 1.0 – 1.3 (TLS 1.3 is current) |
| Security | Weak, vulnerable to attacks | Stronger, more secure |
| Status | Deprecated (since 2015) | Actively maintained |
| Handshake Process | Less efficient, less secure | Improved with stronger ciphers |
| Cipher Suites | Supports outdated algorithms | Modern, secure algorithms |
| Performance | Slower | Faster (especially in TLS 1.3) |
