Calculate TLS 1.2 vs TLS 1.3 handshake latency overhead. TLS 1.3 reduces handshake to 1-RTT (vs TLS 1.2's 2-RTT), saving 50–80ms per new connection.
The TLS Handshake Latency & Overhead Calculator works by applying a well-defined formula to the values you enter. Understanding the formula behind the calculation helps you interpret the result and check that your inputs are correct. Below we break down the key components that drive the TLS Handshake Overhead.
The core formula used by this calculator is:
Result = f(inputs, settings)
Each variable in the formula has a specific meaning:
