cryptojs.swift's Introduction

CryptoJS.swift

Cross-platform cryptographic functions in swift using the Crypto JS library. Allows you to share the same crypto between a native iOS/OSX application and a web application.

Compatible with https://github.com/brix/crypto-js.

⚠️ New project in development

The javascript library used to implement the cryptography in this project is no longer maintained and suffers severe performance limitations over the new WebCrypto API. A new modern library called WebCrypto.swift is being developed. WebCrypto.swift leverages the power of the WebCrypto API while keeping backwards compatibility with this project.

No new development will happen in this repository. Do not submit new feature requests here. If you want something to be implemented, please submit an issue in the new repository:

https://github.com/etienne-martin/WebCrypto.swift

Platforms Supported

iOS
macOS
Web browsers
openSSL

Installation

Drag and drop CryptoJS.swift and the javascript files in your Xcode project.

AES

Supported modes: CBC (the default), CFB, CTR, OFB, ECB
Supported padding schemes: Pkcs7 (the default), Iso97971, AnsiX923, Iso10126, ZeroPadding, NoPadding

// Load the AES module
let AES = CryptoJS.AES()

// Basic AES encryption
let encrypted = AES.encrypt("Secret message", password: "password123")
let decrypted = AES.decrypt(encrypted, password: "password123")

// AES encryption with custom mode and padding
CryptoJS.mode.ECB() // Load custom mode
CryptoJS.pad.Iso97971() // Load custom padding scheme
let encrypted = AES.encrypt("Secret message", password: "password123", options:[ "mode": CryptoJS.mode().ECB, "padding": CryptoJS.pad().Iso97971 ])
let decrypted = AES.decrypt(encrypted, password: "password123", options:[ "mode": CryptoJS.mode().ECB, "padding": CryptoJS.pad().Iso97971 ])

Compatible with OpenSSL

# Basic openSSL AES encryption
openssl enc -aes-256-cbc -e -in /foo/thePlainTextFile.txt -out /bar/theEncryptedFile.txt -pass pass:"password123" -base64

# Basic openSSL AES decryption
openssl enc -aes-256-cbc -d -in /foo/theEncryptedFile.txt -out /bar/theDecryptedFile.txt -pass pass:"password123" -base64

TripleDES

// Load the TripleDES module
let TripleDES = CryptoJS.TripleDES()

// Basic TripleDES encryption
let encrypted = TripleDES.encrypt("secretMessage", password: "password123")
let decrypted = TripleDES.decrypt(encrypted, password: "password123")

DES

// Load the DES module
let DES = CryptoJS.DES()

// Basic DES encryption
let encrypted = DES.encrypt("secretMessage", password: "password123")
let decrypted = DES.decrypt(encrypted, password: "password123")

Hashers

let MD5 = CryptoJS.MD5()
let SHA1 = CryptoJS.SHA1()
let SHA224 = CryptoJS.SHA224()
let SHA256 = CryptoJS.SHA256()
let SHA384 = CryptoJS.SHA384()
let SHA512 = CryptoJS.SHA512()
let SHA3 = CryptoJS.SHA3()
let RIPEMD160 = CryptoJS.RIPEMD160()

var hash = MD5.hash("mystring")
var hash = SHA1.hash("mystring")
var hash = SHA224.hash("mystring")
var hash = SHA256.hash("mystring")
var hash = SHA384.hash("mystring")
var hash = SHA3.hash("mystring")
var hash = SHA512.hash("mystring")
var hash = SHA3.hash("mystring",outputLength: 256)
var hash = RIPEMD160.hash("mystring")

cryptojs.swift's Issues

CBC mode

hello, isn't there a CBC mode ? and a PKCS7 padding ? thanks

How do i install it?

Using with hex encoded message and key.

Please suggest, how to use it with hex encoded message and key.

Can't decrypt data with aes decrypt function in native

I have function used in cross platform application and i want to convert it into native please help me?

function fn_decryptData(var_data,var_key){
	var encrypted = CryptoJS.enc.Base64.parse(var_data);
	var encodedString = btoa(var_key);
	var key = CryptoJS.enc.Base64.parse(encodedString);
	var iv = `CryptoJS.enc.Base64.parse('somestring');`
	return (CryptoJS.enc.Utf8.stringify(CryptoJS.AES.decrypt({ ciphertext: encrypted },key,{ mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7, iv: iv,  })));
}

How to use this in native to decrypt data

Encryption options in Swift 3

I'm trying to set the encryption options in swift 3 and I'm able to get the code to compile with the code below

AES.encrypt(secretMessage: pw, secretKey: key, options: ["mode": CryptoJS.mode.ECB()] as? AnyObject)!
However this causes the app to crash when the code is run. Without the as? AnyObject the code won't compile and I get the error Contextual type 'AnyObject' cannot be used with dictionary literal.

Any suggestions?

NSdata decryption

Hi,
How can I use this library for decrypt nsdata file ?

Thanks,

Convert crypto.js algorithm in swift

Hi, I would like to know how to use the below js method to work in Swift:

let key = "Q8pTgdOC7h25qKVncJlzDA=="
let message = "TestAnitaa009"
let base64Key = CryptoJS.enc.Base64.parse(key);

var iv = base64Key

let encryptedValue = CryptoJS.AES.encrypt(message, base64Key, {
mode: CryptoJS.mode.CBC,
padding: CryptoJS.pad.Pkcs7,
iv: base64Key
});

//The above code outputs = Oz9b31UvNTW8rFfGUOfB5A==

I tried using this library to help to do the same in Swift. But I am not able to. Any help is appreciated. Thanks a lot

Not so much an issue as I need help

Hi first of all I want to thank you for your library. I'm complete noob to data encryption and just need help with it.

Back-end API uses CryptoJS for encrypting their responses. I've tried your library and looks like it works perfect locally. It was easy. But when I try to decrypt server response it returns result "undefined"

Here is the sample of response:

Support of HmacSHA1

does this library support HmacSHA1?

Swift 3 compiler warnings

Using xcode 8.2 I get compiler warnings from the evaluateScript calls, e.g.

cryptoJScontext?evaluateScript(cryptoJS)
the warning is: Expression of type JSValue? is unused

the fix seems to be to change the lines to

let _ = cryptoJScontext?evaluateScript(cryptoJS)

Any comments?

Thanks

    // Load the TripleDES module
     let TripleDES = CryptoJS.TripleDES()

    // Basic TripleDES encryption
    let encrypted = TripleDES.encrypt("secretMessage", secretKey: "password123")
    print("SECRETMESSAGE: " + encrypted)

    // Basic TripleDES decryption
    let decrypted = TripleDES.decrypt(encrypted, secretKey: "password123")
    print("RESULT: " + decrypted)

I get:

Loaded tripledes.js
SECRETMESSAGE: Optional(undefined)
RESULT: Optional(undefined)

What am I missing?
