1. Introduction

 This document registers Hypertext Transfer Protocol (HTTP)
 authentication schemes that 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 registrations below have been added to the IANA "Hypertext
 Transfer Protocol (HTTP) Authentication Scheme Registry" at
 <http://www.iana.org/assignments/http-authschemes> (see Section 5.1
 of [RFC7235]).

 |                |            | connection-oriented) and syntax     |
 |                |            | (use of syntax incompatible with    |
 |                |            | the WWW-Authenticate and            |
 |                |            | Authorization header field syntax). |
