Recept Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director and CEO: Shoken Nakase) is pleased to announce that its Android Kotlin SDK for the digital ID platform "proovy" has successfully passed a test suite verifying technical compatibility with OID4VCI (OpenID for Verifiable Credential Issuance) and OID4VP (OpenID for Verifiable Presentations) using a public test tool provided by the OpenID Foundation (hereinafter, OIDF).
Overview of This Verification
In this verification, we utilized the test tool provided by OIDF (a publicly accessible test suite, prior to its official release as a certified tool) to conduct operational tests for receiving Verifiable Credentials (hereinafter, VC: verifiable digital certificates) in the update of our digital ID wallet SDK, which is currently being offered.
As a result, we successfully achieved seamless issuance and reception of VCs within the provided test environment.
The specific verification environment was as follows:
* VC Issuance Platform: OIDF Test Tool / proovy Issuer API
* VC Reception Environment: Leveraging Android Kotlin SDK
Significance of This Verification and Future Outlook
In the field of digital identity (DID/VC), ensuring interoperability between different systems is extremely important. Among these, "OID4VCI" and "OID4VP" are rapidly becoming widespread as international standard protocols for the issuance and presentation of VCs.
The successful demonstration of normal operation with the OIDF test tool is a very important milestone, proving that "proovy" technology firmly complies with international standards and maintains high technical compatibility with other systems.
Recept Co., Ltd. will continue to promote compliance with global technical standards and strive to expand proovy's functionality and provide/update its wallet SDK to realize a more convenient and secure digital identity society.
Furthermore, in the future, we aim to obtain certification for the same test suite not only in the wallet (SDK) domain but also in the VC issuance and verification platforms, advancing the project towards complete end-to-end international standard compliance.
