3. Proof of Possession creation

The proof of possession (PoP) is a testament that its creator is in possession of something. In the context of the trust onboarding, this PoP takes the form of a JSON Web Token (JWT). Such a PoP can be created with the DID Toolbox. Prerequisites for generating a PoP are:

  • A valid DID log containing at least 1 public key.
  • The corresponding private key for said public key.
  • Possession in form of a string, referred to as nonce.
The generated PoP is only valid within the next 24 hours. 
# Parameter
java -jar didtoolbox.jar create-pop -d $DID_LOG_PATH -k $ID_OF_PUBLIC_KEY -s $PRIVATE_KEY_PEM_FILE_PATH -n $NONCE

# Example
java -jar didtoolbox.jar create-pop -d did.jsonl -k "did:webvh:QmfNchmAvY4EJ7WrxaiWRyrspV9B8dSRzUgcs4CWUggiBD:example.com#assert-key-01" -s .didtoolbox/assert-key-01 -n "99A2BF79-3575-4824-87A5-8F66E6E8C2C7"
The generated PoP is used in the next step and will be further referenced as POP_JWT.
