# crypto-js
|
|
|
|
JavaScript library of crypto standards.
|
|
|
|
## Discontinued
|
|
|
|
Active development of CryptoJS has been discontinued. This library is no longer maintained.
|
|
|
|
Nowadays, NodeJS and modern browsers have a native `Crypto` module. The latest version of CryptoJS already uses the native Crypto module for random number generation, since `Math.random()` is not crypto-safe. Further development of CryptoJS would result in it only being a wrapper of native Crypto. Therefore, development and maintenance has been discontinued, it is time to go for the native `crypto` module.
|
|
|
|
## Node.js (Install)
|
|
|
|
Requirements:
|
|
|
|
- Node.js
|
|
- npm (Node.js package manager)
|
|
|
|
```bash
|
|
npm install crypto-js
|
|
```
|
|
|
|
### Usage
|
|
|
|
ES6 import for typical API call signing use case:
|
|
|
|
```javascript
|
|
import sha256 from 'crypto-js/sha256';
|
|
import hmacSHA512 from 'crypto-js/hmac-sha512';
|
|
import Base64 from 'crypto-js/enc-base64';
|
|
|
|
const message, nonce, path, privateKey; // ...
|
|
const hashDigest = sha256(nonce + message);
|
|
const hmacDigest = Base64.stringify(hmacSHA512(path + hashDigest, privateKey));
|
|
```
|
|
|
|
Modular include:
|
|
|
|
```javascript
|
|
var AES = require("crypto-js/aes");
|
|
var SHA256 = require("crypto-js/sha256");
|
|
...
|
|
console.log(SHA256("Message"));
|
|
```
|
|
|
|
Including all libraries, for access to extra methods:
|
|
|
|
```javascript
|
|
var CryptoJS = require("crypto-js");
|
|
console.log(CryptoJS.HmacSHA1("Message", "Key"));
|
|
```
|
|
|
|
## Client (browser)
|
|
|
|
Requirements:
|
|
|
|
- Node.js
|
|
- Bower (package manager for frontend)
|
|
|
|
```bash
|
|
bower install crypto-js
|
|
```
|
|
|
|
### Usage
|
|
|
|
Modular include:
|
|
|
|
```javascript
|
|
require.config({
|
|
packages: [
|
|
{
|
|
name: 'crypto-js',
|
|
location: 'path-to/bower_components/crypto-js',
|
|
main: 'index'
|
|
}
|
|
]
|
|
});
|
|
|
|
require(["crypto-js/aes", "crypto-js/sha256"], function (AES, SHA256) {
|
|
console.log(SHA256("Message"));
|
|
});
|
|
```
|
|
|
|
Including all libraries, for access to extra methods:
|
|
|
|
```javascript
|
|
// Above-mentioned will work or use this simple form
|
|
require.config({
|
|
paths: {
|
|
'crypto-js': 'path-to/bower_components/crypto-js/crypto-js'
|
|
}
|
|
});
|
|
|
|
require(["crypto-js"], function (CryptoJS) {
|
|
console.log(CryptoJS.HmacSHA1("Message", "Key"));
|
|
});
|
|
```
|
|
|
|
### Usage without RequireJS
|
|
|
|
```html
|
|
<script type="text/javascript" src="path-to/bower_components/crypto-js/crypto-js.js"></script>
|
|
<script type="text/javascript">
|
|
var encrypted = CryptoJS.AES(...);
|
|
var encrypted = CryptoJS.SHA256(...);
|
|
</script>
|
|
```
|
|
|
|
## API
|
|

|
### AES Encryption
|
|
|
|
#### Plain text encryption
|
|
|
|
```javascript
|
|
var CryptoJS = require("crypto-js");
|
|
|
|
// Encrypt
|
|
var ciphertext = CryptoJS.AES.encrypt('my message', 'secret key 123').toString();
|
|
|
|
// Decrypt
|
|
var bytes = CryptoJS.AES.decrypt(ciphertext, 'secret key 123');
|
|
var originalText = bytes.toString(CryptoJS.enc.Utf8);
|
|
|
|
console.log(originalText); // 'my message'
|
|
```
|
|
|
|
#### Object encryption
|
|
|
|
```javascript
|
|
var CryptoJS = require("crypto-js");
|
|
|
|
var data = [{id: 1}, {id: 2}]
|
|
|
|
// Encrypt
|
|
var ciphertext = CryptoJS.AES.encrypt(JSON.stringify(data), 'secret key 123').toString();
|
|
|
|
// Decrypt
|
|
var bytes = CryptoJS.AES.decrypt(ciphertext, 'secret key 123');
|
|
var decryptedData = JSON.parse(bytes.toString(CryptoJS.enc.Utf8));
|
|
|
|
console.log(decryptedData); // [{id: 1}, {id: 2}]
|
|
```

## Release notes
|
|
|
|
### 4.2.0
|
|
|
|
Change default hash algorithm and iteration's for PBKDF2 to prevent weak security by using the default configuration.
|
|
|
|
Custom KDF Hasher
|
|
|
|
Blowfish support
|
|
|
|
### 4.1.1
|
|
|
|
Fix module order in bundled release.
|
|
|
|
Include the browser field in the released package.json.
|
|
|
|
### 4.1.0
|
|
|
|
Added url safe variant of base64 encoding. [357](https://github.com/brix/crypto-js/pull/357)
|
|
|
|
Avoid webpack to add crypto-browser package. [364](https://github.com/brix/crypto-js/pull/364)
|
|
|
|
### 4.0.0
|
|
|
|
This is an update including breaking changes for some environments.
|
|
|
|
In this version `Math.random()` has been replaced by the random methods of the native crypto module.
|
|
|
|
For this reason CryptoJS might not run in some JavaScript environments without native crypto module. Such as IE 10 or before or React Native.
|
|
|
|
### 3.3.0
|
|
|
|
Rollback, `3.3.0` is the same as `3.1.9-1`.
|
|
|
|
The move of using native secure crypto module will be shifted to a new `4.x.x` version. As it is a breaking change the impact is too big for a minor release.
|
|
|
|
### 3.2.1
|
|
|
|
The usage of the native crypto module has been fixed. The import and access of the native crypto module has been improved.
|
|
|
|
### 3.2.0
|
|
|
|
In this version `Math.random()` has been replaced by the random methods of the native crypto module.
|
|
|
|
For this reason CryptoJS might does not run in some JavaScript environments without native crypto module. Such as IE 10 or before.
|
|
|
|
If it's absolute required to run CryptoJS in such an environment, stay with `3.1.x` version. Encrypting and decrypting stays compatible. But keep in mind `3.1.x` versions still use `Math.random()` which is cryptographically not secure, as it's not random enough.
|
|
|
|
This version came along with `CRITICAL` `BUG`.
|
|
|
|
DO NOT USE THIS VERSION! Please, go for a newer version!
|
|
|
|
### 3.1.x
|
|
|
|
The `3.1.x` are based on the original CryptoJS, wrapped in CommonJS modules.
