keri 1.1.3

Dart client for managing KERI based Identifiers on Android system.

Overview

Dart client for managing KERI based Identifiers. See top level README to get acquainted with more generic overview and clients features. For more information about infrastructure see KERI or its whitepaper.

Important

This plugin requires a third party key provider that derives public private key pairs and is able to sign a String using Ed25519 algorithm. For such a usecase, Asymmetric crypto primitives plugin has been designed. The usage of its signer object along with KERI plugin has been provided as an example for this plugin.

Usage

Currently supported functions are:

• initKel - Initializes database for storing events.
• incept - Creates inception event that needs to be signed externally.
• finalizeInception - Finalizes inception (bootstrapping an Identifier and its Key Event Log).
• rotate - Creates rotation event that needs to be signed externally.
• addWatcher - Creates new reply message with identifier's watcher. It needs to be signed externally and finalized with finalizeEvent.
• finalizeEvent - Verifies provided signatures against event and saves it.
• resolveOobi - Checks and saves provided identifier's endpoint information.
• query - Query designated watcher about other identifier's public keys data.
• getKel - Returns Key Event Log in the CESR representation for current Identifier when given a controller.
• getKelByStr - Returns Key Event Log in the CESR representation for current Identifier when given a controller identifier.
• getCurrentPublicKey - Returns pairs: public key encoded in base64 and signature encoded in hex.
• anchor - Creates new Interaction Event along with arbitrary data.
• anchorDigest - Creates new Interaction Event along with provided Self Addressing Identifiers.
