Sigstore maintains its own Private Enterprise Number (57264) with the Internet Assigned Numbers Authority to help identify and organize additional metadata in code signing certificates issued by Fulcio instances. This document aims to provide a simple directory of values in use with an explanation of their meaning.
Note that all values begin from the root OID 1.3.6.1.4.1.57264 registered by Dan Lorenc.
The .1
is added to the root OID for sigstore for all OIDs set by Fulcio.
