SSL Protocol Checker
Check SSL/TLS protocol support
SSL / TLS Protocol Checker
Reference for TLS versions and cipher suites. Generate ready-to-run openssl / nmap commands to inspect a server's certificate and supported protocols.
TLS / SSL Versions
Fatally broken. Must never be enabled.
POODLE attack (CVE-2014-3566). Disable everywhere.
RFC 8996 formally deprecated. Disabled by major browsers.
Deprecated by RFC 8996. Lack of AEAD cipher support.
Widely supported. Use AEAD ciphers (AES-GCM, ChaCha20-Poly1305).
Fastest handshake (1-RTT, 0-RTT), mandatory forward secrecy, modern ciphers only.
Cipher Suite Recommendations
- TLS_AES_256_GCM_SHA384UseECDHE · AES-GCM · 256-bit
- TLS_AES_128_GCM_SHA256UseECDHE · AES-GCM · 128-bit
- TLS_CHACHA20_POLY1305_SHA256UseECDHE · ChaCha20-Poly1305 · 256-bit
- ECDHE-ECDSA-AES128-GCM-SHA256UseECDHE · AES-GCM · 128-bit
- ECDHE-RSA-AES256-GCM-SHA384UseECDHE · AES-GCM · 256-bit
- ECDHE-RSA-CHACHA20-POLY1305UseECDHE · ChaCha20-Poly1305 · 256-bit
- AES128-SHAAvoidRSA · AES-CBC · 128-bit
- RC4-MD5AvoidRSA · RC4-Stream · 128-bit
Prefer AEAD ciphers (GCM, ChaCha20-Poly1305) with ECDHE for forward secrecy. Disable RC4, 3DES, CBC-with-static-RSA, and all NULL/EXPORT ciphers.
