Encryptoid

Encryptoid uses OpenSSL to encrypt and decrypt data with a symmetric key.

Installation

Add this line to your application's Gemfile:

gem 'encryptoid', git: 'https://github.com/daftcode/encryptoid.git'

And then execute:

$ bundle

Configuration

Set a salt for AES encryption algorithm using a configuration block

Encryptoid.configure do |config|
    config.aes_salt = '1234567890'
end

Usage

Create an encryption key and initialization vector

key = Encryptoid.random_key   # generate random key
key = 'super_secret_key'      # or pass own key

iv = OpenSSL::Cipher.new(Encryptoid::AES_ALGORITHM).random_iv

(remember to store your key and iv to be able to decrypt data)

Encryption:

Encryptoid.encrypt('private data', key: key, iv: iv)

Decryption:

Encryptoid.decrypt(encrypted_data, key: key, iv: iv)

File encryption:

Encryptoid.encrypt_file_in_chunks!('~/passwords.txt', chunk_size, key: key, iv: iv)

File decryption:

Encryptoid.decrypt_file('~/passwords.txt', key: key, iv: iv)
