Networking På svenska → Updated: 2026-05-23

The latest TLS version (2018) — faster handshake, safer defaults, end of old insecure ciphers.

1-RTT handshake (vs 2 in TLS 1.2), 0-RTT for repeat visits. Removed: RSA key exchange, SHA-1, CBC mode, compression. Browser support 95%+. Combine with post-quantum cryptography where needed.
