1. Introduction

This document registers Hypertext Transfer Protocol (HTTP) authentication schemes which have been defined in RFCs before the IANA HTTP Authentication Scheme Registry was established.

2. Security Considerations

There are no security considerations related to the registration itself.

Security considerations applicable to the individual authentication schemes ought to be discussed in the specifications that define them.

3. IANA Considerations

The table below provides registrations of HTTP authentication schemes to be added to the IANA HTTP Authentication Scheme registry at <> (see Section 5.1 of [draft-ietf-httpbis-p7-auth]).

Authentication Scheme NameReferenceNotes
Basic[RFC2617], Section 2
Digest[RFC2617], Section 3
Negotiate[RFC4559], Section 3This authentication scheme violates both HTTP semantics (being connection-oriented) and syntax (use of syntax incompatible with the WWW-Authenticate and Authorization header field syntax).
OAuth[RFC5849], Section 3.5.1
