vc-vp-validator

vc-vp-validator is a library designed to provide validation functionality for JSON Web Tokens (JWTs) and JSON objects representing verifiable credentials and presentations. It exposes four validation functions tailored to validate both JSON and JWT credentials and presentations. This library supports various DID methods including did:key, did:ebsi, and did:web.

Features

- Validate JSON Web Tokens (JWTs) and JSON objects representing verifiable credentials (VCs) and presentations (VPs).
- Support for multiple DID methods: did:key, did:ebsi, and did:web.
- Special handling for EBSI issued credentials and DID:key presentations containing EBSI issued credentials.
- Validate DID-based authentication tokens using validateDidAuthToken

Installation

You can install vc-vp-validator via npm:

``bash
npm install vc-vp-validator

Usage

$3

`typescript
import {
validateJwtVC,
validateJsonVC,
validateDcqlVp,
validateDidAuthToken,
} from 'vc-vp-validator';
`

$3

`typescript
const validationResult = await validateJwtVC(jwtCredential, options);
`

$3

`typescript
const validationResult = await validateJsonVC(jsonCredential, options);
`

$3

`typescript
const validationResult = await validateDcqlVp(dcqlPresentation, audience, options);
`

$3

`typescript
const validationResult = await validateDidAuthToken(id_token);
`

$3

Both credential validation functions (validateJwtVC and validateJsonVC) and presentation validation functions (validateDcqlVP) support optional options parameters.

`typescript
export interface CredentialValidationOptions {
didRegistry?: string;
ebsiAuthority?: string;
}
`

`typescript
export interface PresentationValidationOptions {
dcqlQuery?: DCQLQuery;
didRegistry?: string;
ebsiAuthority?: string;
}
`

Validation Response

`typescript
export interface ValidationResult {
valid: boolean;
messages?: string[];
}
``
If the valid property is false, the messages array will include reasons why the credential is not valid.
