Veifgen allows you to create self signed credentials.

flag	description
-o	specify output file
-s	self sign
-t	credential type to set

Creating an identity credential (self signed)

$ node ./src/verifgen.js credential IdentityAndContact-Adam-Smith -o adamsmith-id -s

Creating an a regular credential (self signed)

$ node ./src/verifgen.js credential CurrentEmploymentPosition-2015-Programme-Manager -s -t CurrentEmploymentPosition -o adam-currentemployment

$ node ./src/verifgen.js credential Degree -s -t EducationDegree -o adam-educationdegree

Creating Presentations

Now that you have a set of credentials then you can create presentations for sending to an agent.

Options

flag	description
-o	specify output file
-r	specify the presentation request or credential manifest containing the presentation definition
-i	specify issuer persona
-p	specify x-vnf-protocol-version for presentation (issuer persona is required for v2)
-c	specify all input credential files
-v	specify a vendorOriginContext value

Creating a identity presentation (for issuing)

$ node ./src/verifgen.js presentation -c adamsmith-id -r credential-manifest.json -o adam-id-presentation

Creating a credentials presentation with a vendor origin context(for a disclosure)

$ node ./src/verifgen.js presentation -r presentation-request.json -v eyj!143PRrs -c adamsmith-id adam-currentemployment adam-educationdegree -o adam-creds-presentation.v1
