Verifiable Credentials Collection

This repository contains a collection of all available verifiable credentials powered by the A-SIT Plus VC-K Verifiable Credentials Library for Kotlin Multiplatform. The credentials themselves each live in their own repository and are developed independently of each other without any cross-dependencies. Hence, it is possible to use only a single one in a project or combine as many as desired.
Do check the representation format in the description of each credential! Not every credential supports every representation, even if the VC-K Library supports all of the following formats:

• W3C VC Data Model:
  • Plain JWT (with simple ECDSA signatures)
  • Selective Disclosure JWT
• ISO/IEC 18013-5:2021

All credentials are subject to the terms and conditions of the Apache Licence, Version 2.0 (see each credential's license for more information).

General Usage

Simply add the desired dependency to your project and add a one-liner call to the credential Initializer (see individual credentials for details) to register it.
As of July 2024, we require one snapshot dependency to support all features. Hence, you must add the following repository to your module's build.gradle.kts:

repositories {
    maven(uri("https://raw.githubusercontent.com/a-sit-plus/kotlinx.serialization/mvn/repo"))
}
