I played around with these examples to 1. SHA1 a string 2. hmac(sha1) a string (which isn't shown as an example) and 3) encrypt
cat /proc/crypto shows zstd. However I can't seen to figure out how to use it. I tried the types listed in /proc/crypto and several variations. bind always fails. Is zstd or any compression supported? I'm specifically looking for a way to use them through the kernel I know I could always get the source and compile it or link to a shared object
