Read MoreMore TagHow to speed up handshake times when using ECDHE (and/or ECDSA)
We have had some reports of low-end embedded systems taking 10-20 seconds to establish a TLS connection when generating a shared secret using the ECDH algorithm. We wanted to remind our users of the fixed-point caching mechanism provided by wolfSSL. Users can enable fixed point caching with the configure option –enable-fpecc or by defining FP_ECC […]
