A collection of command line tools to create and validate Verifiable Credentials.
npm install
Create a new decentralized identifier using the web method:
node index.js patrickhochstenbach.net outdir
In the outdir you'll find two files:
private.txt: keep this one safe this is your private keydid.json: publish this document on your website on awell-knownpath.
To prove you are really the owner of the DID, you can create a signed document that contains the DID together with a signature:
node index.js jwt --name "Patrick" jwt outdir/private.txt did:web:patrickhochstenbach.net > outdir/test.jwt
The output outdir/test.jwt can now be sent to a verifier to validate.
node index.js jwt-verify outdir/test.jwt did:web:patrickhochstenbach.net
Create a Verifiable Credential with the example/bachelor_degree.json payload.
The idea is here that e.g. holder creates payload that is signed by an issuer. The issuer uses her DID and private key for that. In this example we assume that the holder and issuer are the same entity.
node index.js vc outdir/private.txt did:web:patrickhochstenbach.net examples/bachelor_degree.json > outdir/test.vc
The holder of the JWT of the previous step can check if it is valid:
node index.js vc-verify outdir/test.vc
Based on a Verifiable Credential in posession a Presentation can be created that can be shared with a third party. The presentation can add other metadata fields to the VC.
node index.js vc-presentation outdir/private.txy did:web:patrickhochstenbach.net outdir/test.vc examples/my_presentation.json > outdir/test.vc.pres
An verifier can validate the received Presentation
node index.js vc-presentation-verify outdir/test.vc.pres
