TLS 1.0

TLS 1.0 API wrappers over the shared TLS 1.2-style context. Header: noxtls_tls10.h.

Deprecated and insecure

TLS 1.0 is deprecated and should not be used for new deployments. It is considered cryptographically weak by modern security standards and fails many compliance baselines.

Usage guidance​

  • Use TLS 1.0 only for controlled legacy interoperability where migration is not yet possible.
  • Restrict exposure (segmented networks, allowlisted peers, short-term exception windows).
  • Prefer upgrading peers to TLS 1.2 or TLS 1.3 as the primary remediation path.

Types​

tls10_context_t​

Alias of tls12_context_t specialized for TLS 1.0 operation.
