TLS 1.3: what developers should know about the API
summary
Covers TLS 1.3 API changes in major crypto libraries (multiple libraries compared), focusing on new features like post‑handshake authentication and 0‑RTT. Explains which new API functions were added, compares the design tradeoffs of those APIs, and recommends best practices for using them so applications can adopt TLS 1.3 with minimal code changes while leveraging new capabilities.
