func Force()
Force forces crypto/tls to restrict TLS configurations to FIPS-approved settings. By design, this call is impossible to undo (except in tests).
func Required() bool
Required reports whether FIPS-approved settings are required.
Required is true if FIPS 140-3 mode is enabled with GODEBUG=fips140=on, or if the crypto/tls/fipsonly package is imported by a Go+BoringCrypto build.
