This commit disables SHA-3 for OpenID when building a FIPS-140 2 compatible binary. While SHA-3 is a crypto. hash function accepted by NIST there is no FIPS-140 2 compliant implementation available when using the boringcrypto Go branch. Therefore, SHA-3 must not be used when building a FIPS-140 2 binary.
