About Keychain

Putting private keys directly into websites is not safe or secure, even ones run by reputable community members. Yet this is currently how nearly every Hive-based site or service currently works. On top of that, most Hive users likely use their master password which is even worse.

The Vessel desktop wallet software is a secure alternative, but it is too difficult to use for the majority of Hive users and does not easily interact with websites - which is Hive's primary use case.

On Ethereum, you never have to enter your private key into a website to use a dApp. You can just use a browser extension like Metamask, which dApp websites can interface with to securely store your keys and broadcast transactions to the blockchain.

Hive Keychain aims to bring the security and ease-of-use of Metamask to the Hive blockchain platform.

Installation

You can download and install the latest published version of the extension for the following browsers:

• Google Chrome (or Opera/Brave): [on Chrome Store][62]
  • Export your keys from Steem keychain (in settings)
  • Download this repository as zip
  • Unzip the downloaded folder
  • Right click on any existing extension > Manage my extensions.
  • Activate developer mode.
  • Click "Load Unpacked" and select the unzipped folder.
  • Import your keys (use the same master password)
• Firefox: [on Firefox Addon Store][63]

Features

The Hive Keychain extension includes the following features:

• Store an unlimited number of Hive account keys, encrypted with AES
• View balances, transaction history, voting power, and resource credits
• Send HIVE and HBD transfers, manage witness votes, and update HP delegation right from the extension
• Manage your Hive Engine tokens
• Power up or down
• Securely interact with Hive-based websites that have integrated with Hive Keychain
• Manage transaction confirmation preferences by account and by website
• Locks automatically on browser shutdown or manually using the lock button

Website Integration

Websites can currently request the Hive Keychain extension to perform the following functions / broadcast operations:

• Send a handshake to make sure the extension is installed
• Decrypt a message encrypted by a Hive account private key (commonly used for "logging in")
• Post a comment (top level or reply)
• Broadcast a vote
• Broadcast a custom JSON operation
• Send a transfer
• Send Hive Engine tokens
• Send Delegations
• Power up/down
• Vote for witnesses
• Create/Remove/Vote for proposals
• Create claimed accounts
• Sign Tx

Usage

Example

An example of a web page that interacts with the extension is included in the "example" folder in the repo. You can test it by running a local HTTP server and going to http://localhost:1337/main.html in your browser.

cd example python -m http.server 1337 //or any other method to run a static server

NOTE: On localhost, it will run on port 1337.

Using Keychain for logins

To login, you can encode a message from your backend and verify that the user can decode it using the requestVerifyKey method. See an example in this project by @howo (@steempress witness):

Frontend

Backend

Alternatively, you can use requestSignTx and verify the signature on your backend.

@hiveio/keychain

This npm module makes it easy to add Keychain support within the browser. It also includes helpful functions to check whether Keychain was used before. It was developed by @therealwolf (witness).

Operations

The Hive Keychain extension will inject a "hive_keychain" JavaScript into all web pages opened in the browser while the extension is running. You can therefore check if the current user has the extension installed using the following code:

hive_keychain

Use the hive_keychain methods listed below to issue requests to the Hive blockchain.
