WebMar 10, 2024 · The SSH connection uses only the default host key type (not other host key types) to authenticate the firewall. You can change the default host key type; the choices are ECDSA (256, 384, or 521) or RSA (2048, 3072, or 4096). Change the default host key type if you prefer a longer RSA key length or if you prefer ECDSA rather than RSA. WebMar 3, 2024 · Server cipher suites and TLS requirements.
