What is CRID (Cryptographic Resource ID)?
A Cryptographic Resource ID (CRID) identifies a resource independently of a URL or network location. The CLI prints it when a resource is published. It is derived from the resource public key, so a compatible opener can check that a signed access grant belongs to the expected resource. Identity, location, and permission are separate: keep the name, issue fresh access for each task.
A CRID is safe to include in documentation or a ticket because the identifier grants no access on its own. An authorized owner uses it to request access links. It stays stable across stops and restarts of the same resource; deleting the resource retires that identity.
How LayerV Implements This
Run qurl publish to create or find a resource, qurl status <CRID> to inspect its local state, and qurl share <CRID> to issue an access link. Send the returned link to a recipient who needs access. Keep the CRID for managing the resource.
