In this document https://www.w3.org/wiki/ActivityPub/Primer/Authentication_Authorization#Server_to_Server there is a dead link to https://web-payments.org/vocabs/security#publicKey.

the owner attribute idea maybe comes from here:

https://docs.joinmastodon.org/spec/activitypub/#publicKey

the sample is strange, i cannot find one of this properties:

https://www.w3.org/ns/activitystreams#publicKey
https://w3id.org/security/v1#publicKey
https://w3id.org/security#publicKey

https://www.w3.org/ns/activitystreams#owner
https://w3id.org/security/v1#owner
https://w3id.org/security#owner

currently i'm confused a bit. a few month ago i talked to the community about publicKey in the actors profile.
I think @steve was answering, that the property publicKeyPem has the namespace https://w3id.org/security#.

i'm using https://w3id.org/security#owner, but forgott, ehere i've found that info. it looks like that https://w3id.org/security#owner is not existing.

Is there a valid document that describes that publicKey stuff ?
