 Encrypt and decrypt data with a given key.
 
 This library was created to allow an easy data
 exchange between Ruby and Node.js.

 ## Usage
 
 ```ruby
-require 'parsel'
+require "parsel"
 
-secret_key = 'mysupersecretkeythatnobodyknowsabout'
-encrypted = Parsel.encrypt(secret_key, 'hello from ruby!')
+secret_key = "mysupersecretkeythatnobodyknowsabout"
+encrypted = Parsel.encrypt(secret_key, "hello from ruby!")
 decrypted = Parsel.decrypt(secret_key, encrypted)
 ```
 
 You can also use Marshal for encrypting/decrypting objects. Notice that this isn't supported by Node.js.
 
 ```ruby
-require 'parsel'
+require "parsel"
 
 data = {user_id: 1234}
 
-secret_key = 'mysupersecretkeythatnobodyknowsabout'
+secret_key = "mysupersecretkeythatnobodyknowsabout"
 encrypted = Parsel::Marshal.encrypt(secret_key, data)
 
 decrypted = Parsel::Marshal.decrypt(secret_key, encrypted)
 #=> {user_id: 1234}
 ```
 
 Alternatively you can use `JSON` as your serializer.
 
 ```ruby
-require 'parsel'
+require "parsel"
 
 data = {user_id: 1234}
 
-secret_key = 'mysupersecretkeythatnobodyknowsabout'
+secret_key = "mysupersecretkeythatnobodyknowsabout"
 encrypted = Parsel::JSON.encrypt(secret_key, data)
 
 decrypted = Parsel::JSON.decrypt(secret_key, encrypted)
 #=> {"user_id" => 1234}
 ```

 By default, this library uses a built-in IV. You may want to change that.
 
 You can globally change the IV like the following:
