Major Highlights/Features

Authorization Endpoint Discovery through Auth Server Well-Known

Feature: Dynamic Authorization Endpoint Retrieval Inji Web now dynamically retrieves the authorization_endpoint from the authorization server’s .well-known configuration, aligning with OAuth standards.

Key Enhancements:

Dynamic Retrieval: Automatically fetches authorization_endpoint during issuer selection.
Backend Caching: Calls handled via backend (mimoto) to avoid CORS issues and cache responses with configurable expiry using Spring Cache.
New Endpoint Introduced: /issuers/{issuer-id}/configuration for fetching issuer and authorization config.
Deprecated: /issuers/{issuer-id}/well-known-proxy (scheduled for removal in next release).
Code Optimization: Clean-up of issuer controller and service files for better maintainability.

New PDF Template Implementation for Existing Use-Cases

Overview: A revamped PDF template is now used for National ID & TAN ID credential downloads use-cases, improving aesthetics, branding, and usability.

Key Features:

Professional Layout: Modern design with clean visuals and prominent placement of credential details.
Prominent QR Code: Displayed clearly on a single page for ease of scanning and offline validation.
Backward Compatible: Compatible with v1.1 Verifiable Credential (VC) format.
Reusable Template: Modular design allows easy adaptation for future use-cases like driver’s license, education credentials, etc.

Implementation Highlights:

Built with HTML for rendering consistency.
Validated across platforms and devices.
Use-case specific tailoring (e.g., National ID, TAN ID).
QR readability verified via Inji Verify.

Multi-Lingual Support for Credential PDF Generation

Feature Overview: Credential PDFs can now be generated in multiple languages using locale-specific templates and resources.

Key Enhancements:

API Update: Added locale parameter in credential generation APIs.
Localized Templates:
- Template Loading: We load templates based on the combination of issuerId and credentialType, not based on language or locale.
- Label Localization in PDF: In the generated PDF, the labels for displayProperties will appear in the selected locale if it is supported by the issuer. If not, the system will default to using the first available locale defined in the displayProperties.
Code Updates:
- Enhanced CredentialController, CredentialService, and CredentialServiceImpl for locale handling.
- Utility methods updated for template resolution.
Testing:
- Unit tests for locale logic.
- End-to-end multilingual credential generation verified.
