I no longer intend to maintain this project. At the very least, this means that you should verify its security yourself before using it. If anyone would like to maintain it, drop me a line.

EasyCipher

A simple gem that uses ruby's OpenSSL package to simplify normal cipher use. It does not rely on any external libraries.

Installation

Add this line to your application's Gemfile:

gem 'easy_cipher'

And then execute:

$ bundle

Or install it yourself as:

$ gem install easy_cipher

Usage

To create an entirely new cipher

cipher = EasyCipher::Cipher.new
encrypted_data = cipher.encrypt "my data"
decrypted_data = cipher.decrypt encrypted_data
=> "my data"

cipher.key
=> "ZE\xD9\xE2B\n2J1\xDF\x10$\x03A\xB95\xE9P\xDF\xD5\xF6\xAA<\x06C\x82~\x06]\xBB\xE1G"

cipher.iv
=> "QHB\xE6\xEDpE\xDCha\x80\x02\xDB\xA5A\xAB"

To create a cipher from a known key, iv

known_cipher = EasyCipher::Cipher.new(known_key, known_iv)

# then use it as normal.

You can also create from base64 encoded values

key64 = my_first_cipher.key64
iv64 = my_first_cipher.iv64
new_cipher = EasyCipher::Cipher.new64(key64,iv64)

# then use it as normal.
# Base64 encodings work with SQL string fields.
