How to test underlying GO TLS implementation?

Help
1

Not familiar with Golang and Caddy’s TLS implementation but is there an equivalent for testing like with OpenSSL/LibreSSL

i.e.

openssl speed rsa4096 rsa2048 ecdsap256 sha256 sha1 md5 rc4 aes-256-cbc aes-128-cbc

??

Just curious how it stacks up https://community.centminmod.com/threads/openssl-1-1-0-pre6-vs-openssl-1-0-2h-vs-openssl-1-0-1e-vs-libressl-2-4-2-vs-libressl-2-3-6.8272/ :slight_smile:

You want to test the performance of Go’s crypto? You can try running some benchmarks using the testing package. Caddy doesn’t (and won’t) have these commands built-in to test speed.

Thanks for your benchmarking work! Hopefully some optimizations will make their way in in the future.

Yup just curious where possible optimisation can be found and how it compares :slight_smile:

guess something along the lines of https://blog.cloudflare.com/go-crypto-bridging-the-performance-gap/

Indeed; Cloudflare has contributed quite a few optimizations to Go’s crypto libraries.
