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:

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

Hi,
Do this library decrypt DES files?
Thanks,
Rafa

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

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

Thanks,
vafa

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?

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

If you comment out CryptoJS.AES then the DES method will not work. Example: Comment out the ViewController class 16-38 in the project, then CryptoJS.TripleDES() will not work.

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

Hi. I've converted CryptoJS.swift to Swift 3 using Xcode 8 converter and the converted file seems to be ok but I can't make it work.

When I try

    // 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?

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

does this library support HmacSHA1?
