Use the Propagate Public Signing Key REST API to take the signing key defined in Artifactory for Release Bundles v2 and propagate it to the trusted list of the Distribution Edges to which the Release Bundles will be distributed.
Using this API eliminates the need to add the key manually to each Distribution Edge one by one.
When working in an Air Gap environment, use this API to add the signing key to the trusted list of the source Artifactory as well. For more information, see Distribute Release Bundles (v2) in an Air Gap Environment.
