Easy way to get a SHA1 hash
yes I'm this lazy.
Add this line to your application's Gemfile:
gem 'rickshaw'
And then execute:
$ bundle
Or install it yourself as:
$ gem install rickshaw
> 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"
