Do you plan to make Temporal FIPS compliant?
There isn’t much resources available for building FIPS compliant Go applications. A few things I found:
A blog post: https://kupczynski.info/2019/12/15/fips-golang.html
A maintained branch of Go using BoringCrypto, a FIPS compliant library: https://github.com/golang/go/tree/dev.boringcrypto/misc/boring
I guess this would mean separate, FIPS compliant builds for those who need them.
