Issue presentation

Verifiable presentations allow holders to share selected information from their verifiable credentials with a verifier. A presentation can bundle multiple credentials and uses cryptographic proofs to ensure authenticity and integrity.

Prerequisites

• Install and configure the SDK
• Define credential schema
• Create a draft
• Issue credential

Create and issue a verifiable presentation

To issue a verifiable presentation that contains multiple credentials, follow the steps below:

1. Initialize the VpDecorator instance and use it to create a VerifiablePresentation:

TypeScript

const vpDecoratorInstance = await client.createVpDecorator(); // VpDecorator

Java

VpDecorator vpDecoratorInstance = new VpDecorator(client);

2. Call the issue method to issue a new verifiable presentation and return its representation (a VerifiablePresentation instance).

TypeScript

const presentation = await vpDecoratorInstance.issue([credential, credential2], privateKey.id); // VerifiablePresentation

Java

VerifiablePresentation presentation = vpDecoratorInstance
        .issue(List.of(credentialId1, credentialId1), privateKey.getId());

You can pass the following arrays to the issue method:

• VerifiableCredential
• CredentialResource ids
• CredentialResource
• UnknownVerifiableCredential

After presentation issuance, you can do the following:

• Share issued presentation.
• Verify issued presentation.
