MetaHash

Here is a ruby library for interacting with the #MetaHash protocol/network.

Installation

Add this line to your application's Gemfile:

gem 'meta_hash'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install meta_hash

Usage

MetaHash::Key

Generate a new #MetaHash key:

key = MetaHash::Key.generate

Read and write a passphrase secured private key from file:

The second argument with passphrase is optional.

If the key is password protected when reading and passphrase is omitted, it will be requested from STDIN.

key = MetaHash::Key.read(
  '~/.metahash_wallets/_unregistered/mhc/0x0123456789abcdef0123456789abcdef0123456789abcdef01.ec.priv',
  'passphrase',
)

key.write(
  "#{key.addr}.ec.priv",
  'passphrase',
)

To get plain public and private keys use:

key.priv                         # private key in DER hex
key.priv :der                    # for binary string

key.pub                          # public key in DER hex
key.pub :der                     # for binary string

Computes an address from a key:

key.addr

Data signing and signature verification:

sig = key.sign('data')                           # sign data

public_key = MetaHash::Key.from_der key.pub :der # get public key from private key
public_key.verify('data', sig)                   # verify data signature

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
