Rickshaw

Easy way to get a SHA1 hash

yes I'm this lazy.

Installation

Add this line to your application's Gemfile:

gem 'rickshaw'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rickshaw

Usage

> Rickshaw::SHA1.hash('LICENSE.txt')
 => "4659d94e7082a65ca39e7b6725094f08a413250a" 

> "hello world".to_sha1
 => "2aae6c35c94fcfb415dbe95f408b9ce91ee846ed" 

> Rickshaw::SHA256.hash("LICENSE.txt")
 => "34c15a6c0d68a79f320f7c0d11ab50f2cb9b0cb9f8bd791ce06340f7448df289"

> "hello world".to_sha256
 => "b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9"

> "hello world".to_md5
 => "5eb63bbbe01eeed093cb22bb8f5acdc3"

We can also pack/unpack our hashes to/from binary strings

> "hello world".to_sha1.packed_bytes
  => "*\xAEl5\xC9O\xCF\xB4\x15\xDB\xE9_@\x8B\x9C\xE9\x1E\xE8F\xED"

> "*\xAEl5\xC9O\xCF\xB4\x15\xDB\xE9_@\x8B\x9C\xE9\x1E\xE8F\xED".unpacked_bytes
  => "2aae6c35c94fcfb415dbe95f408b9ce91ee846ed"

We can also pack/unpack to base64

> "hello world".to_base64
  => "aGVsbG8gd29ybGQ="

> "aGVsbG8gd29ybGQ=".unpack_base64
  => "hello world"
