Usage

• Hash Functions
• Message Authentication Codes

First import Cryptography module.

import Cryptography

Everything you need is available via the Cryptography facade.

Hash Functions

In order to calculate a hash value you simply call Cryptography.hash(message: String, method: HashMethod) -> String with the desired HashMethod

let hashValue = Cryptography.hash("The quick brown fox jumps over the lazy dog", method: HashMethod.SHA1) // "2fd4e1c67a2d28fced849ee1bb76e7391b93eb12"

Message Authentication Codes

In order to calculate a MAC value you simply call authenticate(message: String, key: String, method: MACMethod) -> String with the desired MACMethod

let macValue = Cryptography.authenticate("The quick brown fox jumps over the lazy dog", key: "key", method: MACMethod.HMAC(hashMethod: HashMethod.SHA1)) // "de7c9b85b8b78aa6bc8a7a36f70a90701c9db4d9"

Installation

Compatibility

• OS X 10.9+ / iOS 8.0+ / watchOS 2.0 / tvOS 9.0

Install Using CocoaPods

CocoaPods is a centralized dependency manager for Objective-C and Swift. Go here to learn more.

1. Add the project to your Podfile.

   use_frameworks!
   
   pod 'Cryptography'
   

2. Run pod install and open the .xcworkspace file to launch Xcode.

Install Using Carthage

Carthage is a decentralized dependency manager for Objective-C and Swift.

1. Add the project to your Cartfile.

   github "mlachmish/Cryptography"
   

2. Run carthage update and follow the additional steps in order to add Cryptography to your project.

###Swift Package Manager You can use Swift Package Manager and specify dependency in Package.swift by adding this:

.Package(url: "https://github.com/mlachmish/Cryptography.git", majorVersion: 0)

Manually

Download and drop /Cryptography folder in your project.
