By default, the Pinniped supervisor and concierge use ciphers that
are not supported by FIPS 140-2. If you are deploying Pinniped in an
environment with FIPS compliance requirements, you will have to build
the binaries yourself using the `fips_strict` build tag and Golang's
`go-boringcrypto` fork.
the binaries yourself using Golang 1.19 and the `GOEXPERIMENT=boringcrypto` build tag.
The Pinniped team provides an [example Dockerfile](https://github.com/vmware-tanzu/pinniped/blob/main/hack/Dockerfile_fips)
demonstrating how you can build Pinniped images in a FIPS compatible way.
