6.2.1. Registration Template

Algorithm Name: An identifier for the HTTP signature algorithm. The name MUST be an ASCII string that conforms to the sf-string ABNF rule in Section 3.3.3 of [STRUCTURED-FIELDS] and SHOULD NOT exceed 20 characters in length. The identifier MUST be unique within the context of the registry.

Description: A brief description of the algorithm used to sign the signature base.

Status: The status of the algorithm. MUST start with one of the following values and MAY contain additional explanatory text. The options are:

"Active": For algorithms without known problems. The signature algorithm is fully specified, and its security properties are understood.

"Provisional": For unproven algorithms. The signature algorithm is fully specified, but its security properties are not known or proven.

"Deprecated": For algorithms with known security issues. The signature algorithm is no longer recommended for general use and might be insecure or unsafe in some known circumstances.

Reference: Reference to the document or documents that specify the algorithm, preferably including a URI that can be used to retrieve a copy of the document(s). An indication of the relevant sections may also be included but is not required.
