Components

Inji Certify is a platform designed to manage and facilitate the issuance of Verifiable Credentials (VCs). It features a modular architecture that supports both direct issuance and proxying of VCs from external sources. It interacts with external digital wallets via APIs.

• This layered component diagram represents the architecture of the Inji Certify system.

• The diagram is organized into four distinct layers, each representing a different aspect of the system's functionality:

1. API Layer:

• This layer serves as the entry point for external interactions with the system.

• It exposes various APIs that allow clients to interact with the underlying services.

1. VC Signer and Template Engine:

• This layer is responsible for the creation and signing of Verifiable Credentials (VCs).

• The Template Engine component within this layer handles the generation of credential templates.

• The VC Signer component ensures that the credentials are properly signed and verifiable.

1. Keymanager Service:

• This layer manages cryptographic keys used for signing and verifying credentials.

• It ensures the secure storage and retrieval of keys, and handles key rotation and management tasks.

1. Plugin interaction:

• This foundational layer consists of three plugins that provide essential services to the upper layers:

• Data Provider Plugins: These plugins fetch relevant data from external sources or registries. They retrieve the necessary information and return it to Inji Certify as a JSON object. Inji Certify then utilizes this data to generate and issue the corresponding VCs..

• Audit Plugin: Tracks and logs actions within the system for auditing purposes.

• VC Issuance Plugin: Exposes API for VCI Issuance which internally connects with credential service and sends the Verifiable Credential (VC) issued by the service as a response.

Each layer builds upon the services provided by the layer below it, creating a modular and scalable architecture for the Inji Certify system.
