blk.js

blk.js is a command line utility for blackcoin-more using the client's JSON-RPC API.

Install

npm i -g blk.js

or, for development:

npm i blk.js
cd blk.js
npm link

Install Blackcoin-More with Docker

blk install

Client Config

.blackmore/blackmore.conf must contain the same rpcuser and rpcpassword as your blk.js .env file. This requires root, so you need to add that manually. You can copy and pate the output during install.

rpcuser=
rpcpassword=

SSL

See Enabling SSL on original client.

If you're using this to connect to blackmored across a network it is highly recommended to enable ssl, otherwise an attacker may intercept your RPC credentials resulting in theft of your blackcoins.

When enabling ssl by setting the configuration option to true, the sslStrict option (verifies the server certificate) will also be enabled by default. It is highly recommended to specify the sslCa as well, even if your blackmored has a certificate signed by an actual CA, to ensure you are connecting to your own blackmored.

var client = new blackcoin.Client({
  host: 'localhost',
  port: 15715,
  user: 'username',
  pass: 'password',
  ssl: true,
  sslStrict: true,
  sslCa: fs.readFileSync(__dirname + '/server.cert')
});

If your using a self signed certificate generated with something like

openssl x509 -req -days 365 -in server.cert -signkey server.key -out server.cert

then sslStrict should be set to false because by defult node wont work with untrusted certificates.
