Cordova plugin 121 Indy

A Cordova plugin that wraps Hyperledger Indy functionality.

Currently supported platforms:

• iOS (13+)

Installation

Add the plugin to your Cordova project:

cordova plugin add https://github.com/global-121/121-indy-wrapper-ios.git#0.2.0

Where #0.2.0 can be replaced by a specific tag/release version.

Usage

All API functions are available on the Global121.Indy object. For instance, the setup function can be referenced as follows:

const { setup } = Global121.Indy

Ensure that the plugin is set up properly:

await setup()

Create the wallet. This needs to be called only once:

let password = 'shh, secret!'
await createWallet({ password })

Create a master secret (needed for zero knowledge proofs). Like most API calls this requires the wallet password.

await createMasterSecret({ password })

Generate a new DID (Decentralized Identity):

let { did, verificationKey } = await generateDid({ password })

Create a credential request:

let { json, meta } = await createCredentialRequest({
  password, did, credentialOffer, credentialDefinitionId
})

Store a credential:

let id = await storeCredential({
  password, definition, requestMeta, credential
})

Create a proof:

let proof = await createProof({ password, proofRequest })

Asynchronous calls

The API calls are all asynchronous, and they support both callbacks and promises. So you can use the async/await syntax from the examples above, but also the older syntax where you supply success and error callbacks:

setup(
  function(result) { /* handle success */ },
  function(error) { /* handle error */ }
)

Testing

See the iOS Test-App for running the plugin tests on iOS.
