6.3. HTTP Signature Metadata Parameters Registry

6.3. HTTP Signature Metadata Parameters Registry​

This document defines the signature parameters structure (Section 2.3), which may have parameters containing metadata about a message signature. IANA has created and now maintains a new registry titled "HTTP Signature Metadata Parameters" to record and maintain the set of parameters defined for use with member values in the signature parameters structure. Initial values for this registry are given in Section 6.3.2. Future assignments and modifications to existing assignments are to be made through the Expert Review registration policy [RFC8126].

The DE is expected to do the following:

  • Ensure that the name follows the template presented in Section 6.3.1; this includes ensuring that the length of the name is not excessive while still being unique and recognizable for its defined function.

  • Ensure that the defined functionality is clear and does not conflict with other registered parameters.

  • Ensure that the definition of the metadata parameter includes its behavior when used as part of the normal signature process as well as when used in an Accept-Signature field.
