TLS 1.1

TLS 1.1 API wrappers over the shared TLS 1.2-style context. Header: noxtls_tls11.h.

Deprecated and insecure

TLS 1.1 is deprecated and should not be used for new deployments. It is widely disabled by modern platforms and does not meet current best-practice security requirements.

Usage guidance​

  • Use TLS 1.1 only for temporary compatibility with legacy peers that cannot yet move forward.
  • Minimize scope and lifetime of any TLS 1.1 exception in production.
  • Plan migration to TLS 1.2 or TLS 1.3 as soon as possible.

Types​

tls11_context_t​

Alias of tls12_context_t specialized for TLS 1.1 operation.
