crypto-js's Issues

HmacSHA224 and HmacSHA384 need a fix

There is a bug in src/core.js that causes these (HmacSHA224. HmacSHA384) to return incorrect results.

I forked the repo and applied a fix from:
https://code.google.com/p/crypto-js/issues/detail?id=84

The src patch is: 81077c0
rebuilt files are: 7461bf3
some extra files were generated: 0f87160

Perhaps you would consider this and update your bower to match; there are already too many versions of cryptojs in bower and I would rather not create another one 😄

Add support for argon2 and/or scrypt

Other packages use crypto-js for relying on cryptography (e.g. passport-local-mongoose), so adding support for argon2 or scrypt in this package will make those algorithms available to many projects.

UMD declaration for Global (browser) has an error

I have tried to add separate components:

<script type="text/javascript" src="./bower_components/crypto-js/core.js"></script>
<script type="text/javascript" src="./bower_components/crypto-js/enc-base64.js"></script>
<script type="text/javascript" src="./bower_components/crypto-js/md5.js"></script>
<script type="text/javascript" src="./bower_components/crypto-js/sha1.js"></script>
<script type="text/javascript" src="./bower_components/crypto-js/hmac.js"></script>
<script type="text/javascript" src="./bower_components/crypto-js/evpkdf.js"></script>
<script type="text/javascript" src="./bower_components/crypto-js/cipher-core.js"></script>
<script type="text/javascript" src="./bower_components/crypto-js/mode-ecb.js"></script>
<script type="text/javascript" src="./bower_components/crypto-js/aes.js"></script>

    else {
        // Global (browser)
        factory();
    }
}(this, function (CryptoJS) {

    (function () {
        // Shortcuts
        var C = CryptoJS;
        var C_lib = C.lib;

factory() is called without parameters, which means CryptoJS will be undefined in the factory body. Which lead to errors like:

Uncaught TypeError: Cannot read property 'lib' of undefined - enc-base64.js:19

How to check the password is correct?

Thanks for providing such a wonderful library.
Here is my situation, I have a function to decrypt aes content.

/**
 * decryptAES content
 * @param content 
 * @param pass the password
 * @return content or false when wrong password
 */
function decryptAES(content, pass) {
    var result = false;
    try {
        var bytes = CryptoJS.AES.decrypt(content, pass);
        var content = bytes.toString(CryptoJS.enc.Utf8);
        console.log(content);
        if (content != '') {
            result = content;
        }
    } catch (e) {}
    return result;
}

But, if the content is empty, the function return false, but the password is correct. So, is there a better way to check the password is correct? Thanks for any suggestions.

404 error installing crypto-js through bower

All of a sudden, I'm getting a 404 error when installing crypto-js through bower. This is happening both on my local machine (OSX) and inside a docker VM (debian stretch). I get the following trace when running bower install crypto-js --verbose:

There is an typing error at the end of file "enc-utf8.js". It is "return e.enc.Utf1" and expected to be "return e.enc.Utf8".

Lowercase hexits

How do I get encoding in lowercase hexits?

problem of decrypt (AES, Rabbit and other)

var secret = CryptoJS.ASE.encrypt('user','secret'); // U2FsdGVkX19oU61BktfTADc18gnyiSOCV8DX+F5Plf8=
var ulog = CryptoJS.RC4.decrypt(secret,'secret'); // 75736572

decoding on all algorithms returns 75736572

Don't uglify NPM package source files

The NPM source is uglified, which makes it difficult to debug errors when using it.

I think it's best to not uglify the package, and people interested in doing so for browser usage can then run it through browserify and uglify when needed.

This is related to bitcoinjs/bitcoinjs-lib#57

Uncaught TypeError: Cannot read property 'Word' of undefined

Simply add crypto-js.js on a page and observe the following error:

Uncaught TypeError: Cannot read property 'Word' of undefined
crypto-js.js:2156 (anonymous function)
crypto-js.js:2214 (anonymous function)
crypto-js.js:12 C
crypto-js.js:14 (anonymous function)

Unable to decrypt via AES

I dug around, but I wasn't able to figure out why my example is not running. I saw the example for aes at the bottom of the file https://github.com/brix/crypto-js/blob/master/aes.js#L218.

var CryptoJS = require("crypto-js");

var message = 'test';
var key = '1234abcd0998ijdf';
var cfg = {};

var ciphertext = CryptoJS.AES.encrypt(message, key, cfg);
var plaintext  = CryptoJS.AES.decrypt(ciphertext, key, cfg);

console.log(plaintext);

The output is not plain text, its:

{ words: [ 1952805748, 202116108, 202116108, 202116108 ],
  sigBytes: 4 }

Calling toString() on the object returns 74657374. Any idea where I'm going wrong?

randomBytes is not random enough

https://github.com/evanvosberg/crypto-js/blob/59e465a8055946e84099bfaa8d9ce0e1d1371f51/src/core.js#L274-L281

This is not generating sufficiently random bytes. Math.random was never intended for use in cryptographic applications.

How to get the entire crypto-js.js file?

help

I use python Crypto lib, and javascript crypto-js lib implements encrypt a username, but something is wrong with the output result.

This is python code *

# python2.7.12
from Crypto.Cipher import AES
import base64

KEY = 'ABCDEF1234567890'
IV = 'ABCDEF1234567890'

aes = AES.new(KEY, AES.MODE_ECB, IV)

user = 'root'
user = user + ' ' * (16-len(user))
en_user = aes.encrypt(user)
en_user = base64.b64encode(en_user)
#This is output
print 'en_user', en_user # en_user tPL98ukMrLRcVXPk6zQMFQ==

This is javascript *

/*javascript*/
KEY = 'ABCDEF1234567890';
IV = 'ABCDEF1234567890';
var user='root';

for(tmp=0;tmp<16-user.length;tmp++)
{
    user = user + ' ';
}
var en_user = CryptoJS.AES.encrypt(user, KEY, {iv:IV, mode:CryptoJS.mode.ECB,
                    padding:CryptoJS.pad.NoPadding}).toString();            
en_user = btoa(en_user);
//This is output
console.log(en_user); //VTJGc2RHVmtYMS83UDRRcnpUWDFJUlJlblRTZFlvenRta2M9

Hi,

Where/how can I find a list of the modules.. ?

For example, I want crypto-js/aes but I also want WordArray... but don't know how I can include(?) / access wordarray though only including aes module.. etc?

Thanks,

Crypto-Js has RSA Encryption?

I'm developing a app which needs to RSA Encryption does crypto-js have it and I can use with Angular?

"Object is not a function" when trying to use AES

I have this simple script and it errors out.

Getting different values than that from original cryptoJS for Javascript

I'm doing this on my node server with crypto-js:

var secret = CryptoJS.enc.Base64.stringify( CryptoJS.HmacSHA256(nonce, "my_secret_key") );

and it's "working", but getting different values than doing the same on JS with the original CryptoJS (client side).

Anyone know what I can do to produce the same results? I originally moved it to node so that I could hide my secret key, but having trouble returning what the original code was expecting (different values)

Wanted to know key information

I want to use this for encrypting at client side & decrypting at server side, while sending password.

Which key (Public or Private) to encrypt or which key (Public or Private) to decrypt

how to define crypto method manually? for example `aes-256-cbc` ?

but what makes cfg ?

thx

License file is not included in the NPM package

Please add these files with full license text to the NPM distribution packages. Unfortunately, from the legal standpoint, simply specifying the name of the license is not enough, because it's unclear where to get the EXACT (legally binding) text of that license. This is a major roadblock on our way to using the module, seriously.

Thanks a lot for the great code, and thanks in advance for fixing this blocker.

semver change v3.1.3 to 3.2.0

In the last version v3.1.3, I see that you have moved some files.

This is definitely a breaking change. You should increment the minor version number in order to respect semver.

And probably delete tag v3.1.3 and create a new one 3.2.0.

please add bower.json

Es6 how to correctly import SHA256 algo

given

import pbkdf2 from 'crypto-js/pbkdf2'
import crypto from 'crypto-js'

pbkdf2(password, salt, {
  iterations: 10,
  hasher: crypto.algo.SHA256,
  keySize: 256
})

how do I change this code to import only the SHA256 algo without carrying the whole library around in my bundle?

Please drop requirement on nodejs

I'm using crypto-js without nodejs nor require nor whatever.
This works quite well.

It would be nice if the documentation would stop pretending this is a requirement. I guess it frightens people. Plus there is an example on https://github.com/brix/crypto-js that starts with var CryptoJS = require("crypto-js"); that makes things look impossible to use, especially with free software.

Roll ups like the one on that were available on google were much better in my opinion...

Stupid Question

Hi there.
could you be so kind to describe me something. I need to encrypt some string with secret passphrase with RC4 or other algorithm which is decryptable, then keep the encrypted string (not the object!) in the database and later decrypt it.

I am trying to do it with RC4

    var encrypted = CryptoJS.RC4.encrypt("Message", "Secret Passphrase", { format: JsonFormatter });
console.log("encrypted");
console.log(encrypted);

alert(encrypted);
 
 json=JSON.stringify(encrypted);
 console.log("stringify encrypted");
 console.log(json);
 
 
str=encrypted.toString();
    console.log(encrypted.toString());


    










    var decrypted = CryptoJS.RC4.decrypt(encrypted, "Secret Passphrase", { format: JsonFormatter });
    
    decrypted.toString()

But I am not geting word Message. Why?

Progress indication for encrypting/decrypting

I dont know much about the AES encryption and decryption, im only a js developer and i studied somewhere aes encryption will done on large files using chunks, so im thinking there is a way to publish the progress to variable where encryption/decyrption is going. So that we can show some percentage to users about the encryption/decryption

Automatic key expiration

I am having a scenario where i want to secure the JSON data which i am sending and storing at the client side, and i also want that, that data should be protected, The way to protect this data i suppose is encryption of the data but because the decryption logic and key is also at the client side (to decrypt the encrypted JSON data).

So to protect it i was wondering if we can set something like expiration time of key,

The way i was thinking this is to work that if someone is encrypting the data with the key then encrypted data must have some intelligence that after a period of time this data cannot be decrypted with the key with which it was encrypted(or may be cannot be decrypted at all).

is it possible? i suppose yes , and i don't it is there in the library now.

so i am asking to all members to please provide this facility in this library, or if it is not possible(which i suppose is not) or is not gonna solve a problem please justify.

Thanks.

Crypto in React JS problem

I'm trying to use crypto-js in react but I have a problem.

My action is as follows :

export function userLogin(userData){
return function(dispatch){
    userApi.userExists(userData)
        .then((response) => {
            const tokenEnc = CryptoJS.AES.encrypt(response, 'token');
            //If request is good
            // - Update state to indicate if user is authenticated
            dispatch({type: AUTH_USER});

            localStorage.setItem('token', tokenEnc);

            browserHistory.push(`/users`);
        }).catch((err) => {
            dispatch(authError("The user with the given emailaddress and password doesn't exists. The error is : " + err));
        });

};
}

And the userExists is as follows :

class UserApi {

    static userExists(userData) {
        return new Promise((resolve, reject) => {
            const userFound = users.some(function (user) {
                return ((user.email === userData.email) && (user.password === userData.password));
            });

            if (userFound) {
                const obj = users.filter(function ( obj ) {
                    return obj.email === userData.email;
                })[0];
                resolve(obj.email);
            } else {
                reject("Error! User not found!");
            }
        });
    }
}

export default UserApi;

The problem is when I first time try to log in with the correct credentials I get error TypeError: Cannot read property 'salt' of null.

It can't decrypt it. With the debugger I see that

localStorage.setItem('token', tokenEnc);

isn't executed first time.

If I click again on login, it works perfect.

Any advice?

Malformed Utf-8 data error

i have two string fields in database, both of them are encrypted by cryptojs v3.0.2 in client browser. and the code is like this:

CryptoJS.AES.encrypt(txt, key).toString()

today i got a Malformed Utf-8 data error when decrypting in browsers by cryptojs v3.0.2, one of them (named A)works fine,the other (named B) does not.

so i tried to decrypt them in node.js and browsers using crypto-js v3.1.2, the decrypt code is like this:

    CryptoJS.AES.decrypt(txt, key).toString(CryptoJS.enc.Utf8)

the results is werid (the result from browser and node.js is the same).

i got an empty string when decrypt A

i got the same error when decrypt B

so the behavior is not the same between v3.0.2 and v3.1.2.

could you help me

Error if used AES in AMD

hello,
i tried to use AMD version and link just a aes.js file and method "encrypt" returns with error
cipher-core.js:775 Uncaught TypeError: Cannot read property 'create' of undefined

example of my code:

define([
    'crypto-js/aes',
    'crypto-js/enc-utf8'
], function(
    AES,
    Utf8
) {
    var cipherText = AES.encrypt(text,passphrase).toString();
})

i found it can be fixed in file cipher-core.js by adding "./evpkdf"

define(["./core", "./evpkdf"], factory);

Relationship with sytelus/CryptoJS

I was wondering what kind of relationship exists, if any, between this library and sytelus/CryptoJS. Google shows your library and sytelus's as first ones, and it seems that both are based on Jeff Mott's crypto-js. Would it be possible to merge the two libraries, so that features and updates do not make the two libraries diverge any further and there is one, robust library holding a full cryptographic suite?

Thanks,
Sam

Converting circular structure to JSON

Undefined is not a function at hmac.js:58:18

When calling Hmac functions in this library, I get the following stack trace:

TypeError: undefined is not a function
  at Object.C_algo.HMAC.Base.extend.init (<path>/node_modules/crypto-js/hmac.js:58:18)
  at Object.HmacSHA512 (<path>/node_modules/crypto-js/core.js:726:25)
  <rest of stack trace is my app>

I tried HmacSHA512 and HmacSHA1, using the example provided in the README. Both threw this error. At line 58 in hmac.js, the method 'clamp' is called on key: key.clamp(). It appears this is the undefined function referenced in the stack trace. I'm not sure what this should be replaced with. This is the relevant code in my application:

const crypto = require('crypto-js');
const key = crypto.HmacSHA512(key, secret);
