Introduction

This client abstracts the interface of the Parity Secret Store to just two methods encryptDocument and decryptDocument. It uses a local parity node to sign the generation of keys and stores them remotely into an instance of the secret store.

Get started

Start by adding the package to your dependencies:

npm i @oceanprotocol/secret-store-client

Usage

To get a new instance of SecretStore do the following:

import SecretStore from "@oceanprotocol/secret-store-client"

const secretStore = new SecretStore({
    secretStoreUri: "https://secret-store.dev-ocean.com", 
    parityUri: "http://localhost:8545",
    address: "0xed243adfb84a6626eba46178ccb567481c6e655d",
    password: "unittest",
    threshold: 2,
})

To encrypt a document do the following:

const testDocument = {
    so: "ocean",
    soWow: true,
}

// generate random 64 digit numerical id
const serverKeyId = generateRandomId()
/* this will:
 * - sign the given serverKeyId with the private key from the given address (unlocked with given password)
 * - generate a server key based in the given serverKeyId
 * - generate a document key derived from the server key
 * - store the document key in secret store
 * - encrypt the document and return it
 */
const encryptedDocument = await secretStore.encryptDocument(serverKeyId, testDocument)

To decrypt a document do the following:

/* this will:
 * - sign the given serverKeyId with the private key from the given address (unlocked with given password)
 * - retrieve the document key from secret store
 * - decrypt the document and return it
 */
const decryptedDocument = await secretStore.decryptDocument(serverKeyId, encryptedDocument)

Now both documents are the same:

assert(testDocument.so === decryptedDocument.so)

Development

To start development you need to:

npm i
npm start

Testing

Testing needs a local instance of parity client and secret store. You can spin up these services using oceanprotocol/barge:

git clone https://github.com/oceanprotocol/barge
cd barge
bash -x start_ocean.sh --latest --no-brizo --no-pleuston --local-spree-node 2>&1 > start_ocean.log &

To start test you need to:

npm run test

To run a single testsuite ParityClient for example:

npm run test -- -g "ParityClient"

To watch tests

npm run test:watch

This will start a watcher for changes of the code.

To create code coverage

npm run test:cover

Documentation

To create code documentation

npm run doc

Production build

npm run build

npm releases

For a new patch release, execute on the machine where you're logged into your npm account:

npm run release

In case you have 2FA setup on npm.js, pass a code as One Time Password:

npm run release --otp <yourcode>

Command is powered by release-it package, defined in the package.json.

That's what the command does without any user interaction:

  • create release commit by updating version in package.json
  • create tag for that release commit
  • push commit & tag
  • create a new release on GitHub, with change log auto-generated from commit messages
  • publish to npm as a new release

If you want to create a minor or major release, use these commands:

npm run release-minor
npm run release-major
