PROFILE
Bjorn Molin
Björn Molin developed and maintained the diggsweden/eudiw-wallet-issuer-poc, delivering a robust credential issuance platform aligned with evolving digital identity standards. He engineered secure OAuth2 and OpenID Connect flows, implemented batch and SD-JWT credential support, and integrated OpenID Federation for interoperability. Using Java, Spring Boot, and Redis, Björn focused on backend reliability, security, and compliance, introducing features like JWT-signed state management, PAR enforcement, and dynamic credential configuration. His work addressed both technical debt and new requirements, resulting in a maintainable codebase that supports production-grade workflows, streamlined onboarding, and flexible integration with external wallets and identity providers.

Sep 1, 20252025-09 monthly summary for repository diggsweden/eudiw-wallet-issuer-poc focusing on SD-JWT credential issuance enhancements. Implemented alignment of VCT/credential types with the latest specs, added a parameterized control for issuing specific credential types (credential_configuration_id) via CredentialController and CredentialParam, and extended the SD-JWT payload with an optional personal_administrative_number along with metadata/display updates. No major bugs reported this month; efforts centered on feature delivery, API ergonomics, and spec compliance.

Aug 1, 2025August 2025: Delivered Credential Batch Support in API for the diggsweden/eudiw-wallet-issuer-poc. Introduced a new Credential class and updated CredentialResponse to return a list of credentials, enabling the credential endpoint to provide multiple credentials in a single response. This enhancement reduces client round-trips and simplifies downstream integrations. No major bugs fixed this month; focus was on API evolution, data modeling, and ensuring backward compatibility.

May 1, 2025May 2025 monthly summary for diggsweden/eudiw-wallet-issuer-poc. This period focused on strengthening security and state management for pre-authorized credential flows, stabilizing Android wallet interactions, and accelerating PID issuance through policy and visibility enhancements. Key features delivered and major fixes: - JWT-signed state parameters for pre-authorized credential offers, with container runtime detection (Podman/Docker) in the script to ensure reliable operation across environments. - PAR endpoint metadata and enforcement to require PAR for authorization requests, tightening control over authorization flows. - PID issuance streamlined by removing requireAuthorizationConsent in OidFederatedRegisteredClientRepository, reducing friction in issuance. - Android Redis retrieval workarounds introduced to stabilize the wallet app pre-authorization flow (updates to pre-auth code retrieval and credential offers retrieval). - Front-page update adding a link to the PID Token Library (PoC) to facilitate testing and reference. Major fixes: - OAuth2 redirect URI verification disabled in CustomRedirectUriValidator to support testing scenarios (with verbose logging of requested URIs). Overall impact and accomplishments: - Enhanced security and governance for credential offers via JWT signing and PAR enforcement. - Improved onboarding reliability for Android wallets through Redis flow stabilization. - Accelerated PID issuance with reduced friction and clearer testing pathways via library integration. - Clear, testable foundation for future enhancements with explicit metadata and runtime-detection improvements. Technologies and skills demonstrated: - OAuth2, JWT, PAR, Redis, container runtime detection (Podman/Docker) - Java/Spring-based configuration, OIDC repository adjustments - Frontend content integration and PoC library testing integration
