Entra VerifiedID - JSON and Content Readiness Assessment

Last Updated: 2025-01-27
Status: ✅ Ready for JSON, ⚠️ Limited for other content types

---

Executive Summary

Entra VerifiedID integration is READY for JSON content with full support for:

• ✅ JSON request/response handling

• ✅ Credential verification with JSON payloads
• ✅ API responses in JSON format

Limited support for other content types:

• ⚠️ Documents must be base64-encoded strings
• ⚠️ No direct binary file handling
• ⚠️ No image/PDF processing built-in
• ⚠️ Claims are restricted to string values only

---

JSON Support - ✅ FULLY READY

1. Request/Response Handling

Status: ✅ COMPLETE

All API endpoints properly handle JSON:

// Request headers
headers: {
  'Content-Type': 'application/json',
  Authorization: `Bearer ${token}`,
}

// Request body
body: JSON.stringify(requestBody)

// Response parsing
const data = await response.json()

Locations:

• packages/auth/src/entra-verifiedid.ts - Lines 151, 154, 162, 209, 212, 221, 259, 262, 270
• services/identity/src/entra-integration.ts - All endpoints use JSON

2. TypeScript Interfaces

Status: ✅ COMPLETE

All JSON structures are properly typed:

// Request interface
export interface VerifiableCredentialRequest {
  claims: Record<string, string>;
  pin?: string;
  callbackUrl?: string;
}

// Response interface
export interface VerifiableCredentialResponse {
  requestId: string;
  url: string;
  expiry: number;
  qrCode?: string;
}

// Credential interface
export interface VerifiedCredential {
  id: string;
  type: string[];
  issuer: string;
  issuanceDate: string;
  expirationDate?: string;
  credentialSubject: Record<string, unknown>; // ✅ Flexible
  proof: { ... };
}

3. API Endpoints - JSON Schema Validation

Status: ✅ COMPLETE

All endpoints have JSON schema validation via Fastify:

schema: {
  body: {
    type: 'object',
    required: ['claims'],
    properties: {
      claims: {
        type: 'object',
        description: 'Credential claims',
      },
      // ...
    },
  },
  response: {
    200: {
      type: 'object',
      properties: {
        requestId: { type: 'string' },
        url: { type: 'string' },
        qrCode: { type: 'string' },
      },
    },
  },
}

Endpoints:

• ✅ POST /vc/issue/entra - JSON request/response
• ✅ POST /vc/verify/entra - JSON request/response
• ✅ POST /eidas/verify-and-issue - JSON request/response

---

Content Type Support

1. JSON Content - ✅ READY

Status: ✅ FULLY SUPPORTED

• ✅ All API requests use application/json
• ✅ All responses are JSON
• ✅ Proper JSON parsing and stringification
• ✅ Type-safe JSON handling with TypeScript

Example:

{
  "claims": {
    "email": "user@example.com",
    "name": "John Doe",
    "role": "member"
  },
  "pin": "1234",
  "callbackUrl": "https://example.com/callback"
}

2. Base64-Encoded Documents - ⚠️ LIMITED

Status: ⚠️ BASIC SUPPORT

Documents must be provided as base64-encoded strings:

// eIDAS endpoint expects base64 string
{
  "document": "base64-encoded-document",
  "userId": "user-123",
  "userEmail": "user@example.com"
}

Limitations:

• ⚠️ No automatic encoding/decoding
• ⚠️ No file type validation
• ⚠️ No size limits enforced
• ⚠️ No MIME type handling

Recommendation: Add helper functions for file handling.

3. Binary Content - ❌ NOT SUPPORTED

Status: ❌ NOT SUPPORTED

• ❌ No direct binary file upload
• ❌ No multipart/form-data support
• ❌ No file streaming
• ❌ No image/PDF processing

Workaround: Convert to base64 before sending.

4. QR Codes - ✅ SUPPORTED

Status: ✅ SUPPORTED

QR codes are returned as base64-encoded data URLs in JSON:

{
  "requestId": "abc123",
  "url": "https://verifiedid.did.msidentity.com/...",
  "qrCode": "data:image/png;base64,iVBORw0KGgoAAAANS..."
}

---

Claims Handling - ⚠️ TYPE RESTRICTION

Current Implementation

Status: ⚠️ RESTRICTED TO STRINGS

export interface VerifiableCredentialRequest {
  claims: Record<string, string>; // ⚠️ Only string values
  // ...
}

Limitation: Claims can only be string values, not:

• ❌ Numbers
• ❌ Booleans
• ❌ Nested objects
• ❌ Arrays

Credential Subject - ✅ FLEXIBLE

Status: ✅ FLEXIBLE

export interface VerifiedCredential {
  credentialSubject: Record<string, unknown>; // ✅ Any type
  // ...
}

Credential subject can contain any JSON-serializable value.

---

Recommendations for Enhancement

1. Enhanced Claims Type Support

Priority: Medium

// Enhanced interface
export interface VerifiableCredentialRequest {
  claims: Record<string, string | number | boolean | null>;
  // Or use JSON Schema validation
}

2. File Handling Utilities

Priority: High

// Add helper functions
export async function encodeFileToBase64(file: Buffer | string): Promise<string> {
  // Handle file encoding
}

export function validateBase64Document(base64: string, maxSize?: number): boolean {
  // Validate document
}

3. Content Type Detection

Priority: Medium

export function detectContentType(data: string | Buffer): string {
  // Detect MIME type
  // Validate against allowed types
}

4. Document Processing

Priority: Low (can use external services)

// Integration with document processing
export async function processDocumentForEntra(
  document: Buffer,
  options: DocumentProcessingOptions
): Promise<ProcessedDocument> {
  // OCR, validation, etc.
}

Testing JSON Readiness

Test JSON Request

curl -X POST https://your-api/vc/issue/entra \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer <token>" \
  -d '{
    "claims": {
      "email": "test@example.com",
      "name": "Test User"
    }
  }'

Expected JSON Response

{
  "requestId": "abc123",
  "url": "https://verifiedid.did.msidentity.com/...",
  "qrCode": "data:image/png;base64,...",
  "expiry": 3600
}
