Package crypto works with or without cgo, which is great. However, to make it work without cgo required setting the build tag `nocgo`. It's common to disable cgo by instead just setting the environment variable `CGO_ENABLED=0`. Setting this environment variable does _not_ implicitly set the build tag `nocgo`. So projects that try to build the crypto package with `CGO_ENABLED=0` will fail. I have done this myself several times. Until today, I had just assumed that this meant that this package requires cgo. But a small build tag change will make this case work. Instead of using `nocgo` and `!nocgo`, we can use `!cgo` and `cgo`, respectively. The `cgo` build tag is automatically set if cgo is enabled, and unset if it is disabled. |
