mruby-digest
=========

This library is a fork of [github.com/iij/mruby-digest](https://github.com/iij/mruby-digest).
Unlike the original, this fork does not have any dependencies; it uses [picohash](https://github.com/kazuho/picohash) - a public domain library for hash calculation.

## Features

Message Digest and HMAC classes are available.  They are compatible with CRuby's ones.

- Digest::MD5, Digest::RMD160, Digest::SHA1, Digest::SHA256, Digest::SHA384 and
  Digest::SHA512
  - Note: some of them are not available if libcrypto.a does not support them on your system.
- Digest::HMAC

## Install
 - add conf.gem line to `build_config.rb`

```ruby
MRuby::Build.new do |conf|

    # ... (snip) ...

    conf.gem :git => 'https://github.com/iij/mruby-digest.git'
end
```

## Usage
```ruby
Digest::MD5.digest('ruby')
Digest::MD5.hexdigest('ruby')
```
