Build Fails on RHEL 6

[swsnider]

When building using the distro's golang (go version go1.4.2 linux/amd64), the build fails with message:

# github.com/hashicorp/vault/builtin/logical/pki
builtin/logical/pki/cert_util.go:188: undefined: elliptic.P224

This is because RHEL/Fedora remove certain curves from crypto packages because of patent encumbrances (see coreos/etcd-ca#22, for example). Please consider removing this curve (p256 is still available).

Tagged as a bug/enhancement. What a world when mathematical curves are patent encumbered.

The referenced etcd bug states that they don't think it should be on them to remove functionality useful to many because one distribution chooses to patch it out. I agree with this stance; we build against official released Go. You can either build Go yourself on RHEL and then build Vault with it, or you can use our signed binary releases which are built against official Go releases.
