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

<span class="h2"><a class="selflink" id="section-1" href="#section-1">1</a>. Introduction</span>
This document registers Hypertext Transfer Protocol (HTTP)
authentication schemes that have been defined in RFCs before the IANA
HTTP Authentication Scheme Registry was established.
<span class="h2"><a class="selflink" id="section-2" href="#section-2">2</a>. Security Considerations</span>
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.
<span class="h2"><a class="selflink" id="section-3" href="#section-3">3</a>. IANA Considerations</span>
The registrations below have been added to the IANA "Hypertext
Transfer Protocol (HTTP) Authentication Scheme Registry" at
<<a href="http://www.iana.org/assignments/http-authschemes">http://www.iana.org/assignments/http-authschemes</a>> (see <a href="./rfc7235#section-5.1">Section 5.1
of [RFC7235]</a>).

| Basic | [<a href="./rfc2617" title=""HTTP Authentication: Basic and Digest Access Authentication"">RFC2617</a>], | |

| Negotiate | [<a href="./rfc4559" title=""SPNEGO-based Kerberos and NTLM HTTP Authentication in Microsoft Windows"">RFC4559</a>], | This authentication scheme violates |
| | <a href="#section-3">Section 3</a> | both HTTP semantics (being |
| | | connection-oriented) and syntax |
| | | (use of syntax incompatible with |
| | | the WWW-Authenticate and |
| | | Authorization header field syntax). |
