Add Keys

This tutorial explains how to add public keys to a DID registered on InfraDID parachain.

Before you begin

Before you begin, Make sure you have the following:

• Creating InfraDID

Adding Public Keys to InfraDID

InfraDID registered on the chain allows management of various items, one of which is the list of public keys. By storing a list of public keys that a specific DID can use on the chain, it makes it public for other users to inspect the Document of a specific DID.

To add public keys to InfraDID, follow these steps:

1. Visit the InfraBlockchain Explorer and follow the steps below.

• Go to Developer - Extrinsic and select the addKeys extrinsic of the didModule palette.

  Configure it as shown below and trigger the extrinsic:

  

  add-keys

  Encode call data:

Removing Public Keys from InfraDID

To remove public keys from InfraDID, follow these steps:

1. Visit the InfraBlockchain Explorer and follow the steps below.

• Go to Developer - Extrinsic and select the removeKeys extrinsic of the didModule palette.

  Configure it as shown below and trigger the extrinsic:

  

  remove-keys

Adding and Removing Public Keys from InfraDID Using the infra-did-js Library

To add and remove public keys from InfraDID using the infra-did-js library:

1. Install the infra-did-js library.

   yarn add infra-did-js

2. Write code to set up the basic configuration code for accessing InfraDID chain, as shown below:

   import  {InfraSS58, CRYPTO_INFO} from 'infra-did-js';
   
   const txfeePaterAccountKeyPair = await InfraSS58.getKeyPairFromUri('//Alice', 'sr25519');
   const confBlockchainNetwork = {
     networkId: 'space',
     address: 'ws://localhost:9944',
     // seed or keyPair required
     txfeePayerAccountKeyPair,
     // or txfeePayerAccountSeed: 'TX_FEE_PAYER_ACCOUNT_SEED'
   };
   const conf = {
     ...confBlockchainNetwork,
     did: 'did:infra:space:5CRV5zBdAhBALnXiBSWZWjca3rSREBg87GJ6UY9i2A7y1rCs',
     // seed or keyPair required
     seed: 'DID_SEED',
     // keyPair: keyPair,
     controllerDID: 'did:infra:space:5HdJprb8NhaJsGASLBKGQ1bkKkvaZDaK1FxTbJRXNShFuqgY'
     controllerSeed: 'DID_CONTROLLER_SEED',
     // or controllerKeyPair: controllerKeyPair
   };
   const infraApi = await InfraSS58.createAsync(conf);

3. Write code to add public keys to InfraDID:

   // Add keys
   await infraApi.didModule.addKeys(SOME_DID_KEY);

4. Alternatively, write code to remove public keys from InfraDID:

   // Remove Keys
   await infraApi.didModule.removeKeys(DID_KEY_IDS);
