Un-negotiated Raw Public Key RFC 7250 accepted in place of an X.509 certificate, bypassing chain validation. A raw public key has no chain, so ParseCertRelative accepts it without performing any trust verification; it must therefore only be accepted when RPK was actually negotiated for that peer...
