Tari Crypto iOS

This iOS framework is a wrapper around the Tari Crypto library. It contains the native crypto library and the header file, and the necessary wrapper and model classes to enable the developers to generate key pairs, sign messages and verify message signatures.

Requirements

• iOS 10.0+

Installation

Using Cocoapods

CocoaPods (iOS 10+)

You can use CocoaPods to install TariCrypto by adding it to your Podfile:

use_frameworks!

target 'MyApp' do
    pod 'TariCrypto'
end

Usage

Sample program that illustrates message signing and verification:

import TariCrypto

// create a key pair from hex string representations, and sign & verify
let keyPairFromHex = TariKeyPair(
    privateKey: TariKey(hexString: "A35F68A5054C9721874CDE2553B80F98338952783C6E1687A2E8454B0D5BA200")!,
    publicKey: TariKey(hexString: "50C5624924CE9B806FE40A94CA20B029DB6AC6DA098B3E48B89CE2695B265E71")!
)
let message = "A random message."
let signedMessage = try keyPairFromHex.privateKey.signMessage(message: message)
var isVerified = try keyPairFromHex.publicKey.verifySignature(signedMessage: signedMessage)
print("Is first message verified? \(isVerified)")

// or, do the same with a random key pair, and sign & verify
let randomKeyPair = TariKeyPair.generateRandom()
let anotherMessage = "Another random message."
let anotherSignedMessage = try randomKeyPair.privateKey.signMessage(message: anotherMessage)
isVerified = try randomKeyPair.publicKey.verifySignature(signedMessage: anotherSignedMessage)
print("Is second message verified? \(isVerified)")

Program output:

Is first message verified? true
Is second message verified? true
