-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')
-```
