Nat Sakimura:

In section 9, private\_key\_jwt, it says: 

> Clients that have registered a public key sign a JWT using that key

Literally, “that key” is “public key” here, and thus this is wrong, though all of us who know about public key cryptography understand that it means the paired private key \(signing key\). 

Proposes to amend the sentence to be: 

> Clients that have registered a public key sign a JWT using the paired private key.
