About this tool
TLS Configuration Reference
The TLS Configuration Reference covers TLS version requirements, cipher suite selection for PFS, certificate key type recommendations, HSTS configuration, and OCSP stapling.
• Confirm which TLS versions are acceptable for a PCI-DSS compliance review
• Look up which cipher suites enable Perfect Forward Secrecy
• Reference HSTS header format and preload list requirements
• Compare ECDSA P-256 vs RSA 2048 for a new certificate selection

FAQ
What does this tool tell you?
The TLS Configuration Reference covers TLS version requirements, cipher suite selection for PFS, certificate key type recommendations, HSTS configuration, and OCSP stapling.
What affects the result most?
TLS 1.3: mandatory for new deployments — removes weak cipher suites, enforces PFS, 0-RTT resumption. TLS 1.2: still acceptable, disable SHA-1 and RC4 cipher suites. TLS 1.0 and 1.1: deprecated by RFC 8996 (2021), disabled by major browsers.
How should I use the result?
Use this tool to orient quickly to the concepts, field names, or values you are about to look up in a full specification or vendor documentation. It summarizes the common cases; the authoritative source remains whichever standard or vendor doc defines the values themselves.
