SwiftlyCrypto

Encrypt your data like using other Swift APIs

SwiftlyCrypto is based on SwCrypt from @soyersoyer

Why SwiftlyCrypto?

SwiftlyCrypto is a non-abstract crypto library. Developers can benefit from SwiftlyCrypto's figurative API.

SwiftlyCrypto will never define a type as its original value. (Like Data or String.) This feature can be very useful in large projects, because it makes the code more readable.

SwiftlyCrypto is repackaged from SwCryt. Thanks @soyersoyer's project SwCrypt!

Quick Tutorial

You should import SwiftlyCrypto to your code at the beginning.

import SwiftlyCrypto

RSA

Generate key pair

let (privateKey, publicKey) = RSA.generateKeyPair()

Get PEM format keys

let pemPrivateKey = privateKey.toPKCS1()
let pemPublicKey = publicKey.toPKCS8()

Encrypt & decrypt private key

let encryptedPrivateKey = try privateKey.encryptedKey("password")
let decryptedPrivateKey = try RSAPrivateKey(encryptedPrivateKey, password: "password")

Get public key from private key

let publicKey = try privateKey.getPublicKey()

Encrypt & Decrypt

let text = "Hello, world!"
let raw = RSARawValue(text)
let encrypted = try raw.encrypt(publicKey: publicKey)
let decrypted = try encrypted.decrypt(privateKey: privateKey)

Sign & Verify

let text = "Hello, world!"
let raw = RSARawValue(text)
let signed = try raw.sign(privateKey: privateKey)
let verifyResult = try signed.verify(message: raw, publicKey: publicKey) // true for success, otherwise false

AES

Generate random Key & IV

let randomKey = AES.generateRandomKey()
let randomIV = AES.generateRandomIV()

Set your own Key & IV

let key = AESKey("password")
let iv = try AESIV(fromHexString: "12345678901234567890123456789012")

Encrypt & Decrypt

let text = "Hello, world!"
let raw = AESRawValue(text)
let encrypted = try raw.encrypt(key: key, iv: iv)
let decrypted = try encrypted.decrypt(key: key, iv: iv)

Encrypt with random generation

// generate both key and iv
let raw = AESRawValue("Hello, world!")
let key = AESKey()
let iv = AESIV()
let encrypted = try raw.encrypt(randomKey: &key, randomIV: &iv)

// generate key
let raw = AESRawValue("Hello, world!")
let key = AESKey()
let iv = try AESIV(fromHexString: "12345678901234567890123456789012")
let encrypted = try raw.encrypt(randomKey: &key, iv: iv)

// generate iv
let raw = AESRawValue("Hello, world!")
let key = AESKey("password")
let iv = AESIV()
let encrypted = try raw.encrypt(key: key, randomIV: &iv)

Check whether the key or IV is empty

// true for empty, otherwise false
key.isEmpty
iv.isEmpty
