SecurityService - An easy way to encrypt/decrypt and hash Data

SecurityService

Do you always have trouble trying to implement cryptography? Well, you don't need to worry anymore! In this framework I have created a wrapper on top of one of the most beloved crypto frameworks out there, the CryptoSwift.

Why? Just because I wanted to repeat this setup in many projects and then I have created the SecurityService.

Setup

CocoaPods

If you are using CocoaPods, add this to your Podfile and run pod install.

target 'Your target name' do
    pod 'SecurityService', '~> 1.0'
end

Manual Installation

If you want to add it manually to your project, without a package manager, just copy all files from the Classes folder to your project.

Usage

Creating the Service

To create an instance of the service, you only need to import the framework and instantiate the SecurityService:

import SecurityService
let service = SecurityService()

If you want to have some specific configuration, you can create it like this:

import KeyValueStorage
import SecurityService

service = SecurityService(storage: KeyValueStorage(),
                          cipherKey: "keykeykeykeykeyk",
                          cipherIv: "drowssapdrowssap",
                          hashSalt: "nacllcan",
                          hashIterations: 4096,
                          hashKeyLength: 32,
                          hashVariant: .sha256)

Encrypt/Decrypt

With SecurityService it is very easy to encrypt/decrypt Data, it uses the AES-GCM algorithm and you just need to call it like this:

let source = "some string"
let data = source.data(using: .utf8)!
let encrypted = service.encrypt(data: data)
let decrypted = service.decrypt(data: encrypted!)
let result = String(data: decrypted!, encoding: .utf8)

Hash passwords

You can also hash passwords in order to protect the user's data using the PBKDF2 algorithm:

let password = "something"
let hashPassword = service.hash(password: password)

Cryptography Notice

This distribution includes cryptographic software. The country in which you currently reside may have restrictions on the import, possession, use, and/or re-export to another country, of encryption software. BEFORE using any encryption software, please check your country's laws, regulations and policies concerning the import, possession, or use, and re-export of encryption software, to see if this is permitted. See http://www.wassenaar.org/ for more information.
