Verifying Documents (CLI)

For the current step, you can either opt to use the CLI or Code.

This document provides a step-by-step guide on how to verify the authenticity and integrity of a signed Verifiable Credential (VC) using the w3c-cli tool. The verification process ensures that the credential has not been tampered with and validates the issuer’s signature.

Prerequisites:

• Install the w3c-cli tool on your system.
• Ensure you have the JSON file of the signed Verifiable Credential (e.g., signed_vc.json).

Installation

Install CLI:

Note Remember to install the cli globally

npm install -g @trustvc/w3c-cli

Verification Process

Open a terminal or command prompt on your system.

Run the verify command:

w3c-cli verify

Provide the path to your Verifiable Credential JSON file when prompted:

? Please enter the path to your verifiable credential JSON file: ./signed_vc.json

Replace ./signed_vc.json with the path to your credential file if it is located in a different directory.

View the verification result: After running the command, you will receive an output similar to the following:

Verification result: true
Credential status verification result: "revocation:false"

Verification result: true indicates that the cryptographic proofs in the credential are valid and the credential has not been altered.

Credential status verification result: "revocation:false" confirms that the credential has not been revoked.

Notes

Ensure that the credential file is in the correct JSON format and adheres to the W3C Verifiable Credentials Data Model.

If the verification fails, double-check the file path and the format of the credential JSON file.

If the status verification shows revocation:true, it means the credential has been revoked and is no longer valid.
