#### Plain text encryption



```javascript

import CryptoJS from "rn-crypto-js";



// Encrypt

const ciphertext = CryptoJS.AES.encrypt('my message', 'secret key 123').toString();



// Decrypt

const decryptedData  = CryptoJS.AES.decrypt(ciphertext, 'secret key 123').toString(CryptoJS.enc.Utf8);

console.log(decryptedData); // 'my message'

```



#### Object encryption



```javascript

import CryptoJS from "rn-crypto-js";

const data = [{id: 1}, {id: 2}]



// Encrypt

const ciphertext = CryptoJS.AES.encrypt(JSON.stringify(data), 'secret key 123').toString();



// Decrypt

const decryptedString  = CryptoJS.AES.decrypt(ciphertext, 'secret key 123').toString(CryptoJS.enc.Utf8);

const decryptedData = JSON.parse(decryptedString);

console.log(decryptedData); // [{id: 1}, {id: 2}]

```



## Hashing

### MD5

MD5 is a widely used hash function. It's been used in a variety of security applications and is also commonly used to check the integrity of files. Though, MD5 is not collision resistant, and it isn't suitable for applications like SSL certificates or digital signatures that rely on this property.



```javascript

const hash = CryptoJS.MD5("Message").toString();

```



### SHA1

The SHA hash functions were designed by the National Security Agency (NSA). SHA-1 is the most established of the existing SHA hash functions, and it's used in a variety of security applications and protocols. Though, SHA-1's collision resistance has been weakening as new attacks are discovered or improved.



```javascript

const hash = CryptoJS.SHA1("Message").toString();

```



### SHA256

SHA-256 is one of the four variants in the SHA-2 set. It isn't as widely used as SHA-1, though it appears to provide much better security.



```javascript

const hash = CryptoJS.SHA256("Message").toString();

```

### SHA224

```javascript

const hash = CryptoJS.SHA224("Message").toString();

```



### SHA384

```javascript

const hash = CryptoJS.SHA384("Message").toString();

```



### SHA512

```javascript

const hash = CryptoJS.SHA512("Message").toString();

```



### SHA3

SHA-3 is the winner of a five-year competition to select a new cryptographic hash algorithm where 64 competing designs were evaluated.

```javascript

const hash = CryptoJS.SHA3("Message").toString();

```



### RIPEMD160

```javascript

const hash = CryptoJS.RIPEMD160("Message").toString();

```



## HMAC

### HMAC-MD5

```javascript

const hash = CryptoJS.MD5("Message").toString();

```



### HMAC-SHA1

```javascript

const hash = CryptoJS.SHA1("Message").toString();

```



### HMAC-SHA256

```javascript

const hash = CryptoJS.SHA256("Message").toString();

```

### HMAC-SHA224

```javascript

const hash = CryptoJS.SHA224("Message").toString();

```



### HMAC-SHA384

```javascript

const hash = CryptoJS.SHA384("Message").toString();

```



### HMAC-SHA512

```javascript

const hash = CryptoJS.SHA512("Message").toString();

```



### HMAC-SHA3

```javascript

const hash = CryptoJS.SHA3("Message").toString();

```



### HMAC-RIPEMD160

```javascript

const hash = CryptoJS.HMACRIPEMD160("Message").toString();

```



## Ciphers



### AES

The Advanced Encryption Standard (AES) is a U.S. Federal Information Processing Standard (FIPS). It was selected after a 5-year process where 15 competing designs were evaluated.



```javascript

const encrypted = CryptoJS.AES.encrypt("Message", "5ecret").toString();

​

const decrypted = CryptoJS.AES.decrypt(encrypted, "5ecret").toString(CryptoJS.enc.Utf8);

```



### DES

DES is a previously dominant algorithm for encryption, and was published as an official Federal Information Processing Standard (FIPS). DES is now considered to be insecure due to the small key size.



```javascript

const encrypted = CryptoJS.DES.encrypt("Message", "5ecret").toString();

​

const decrypted = CryptoJS.DES.decrypt(encrypted, "5ecret").toString(CryptoJS.enc.Utf8);

```



### TripleDES

Triple DES applies DES three times to each block to increase the key size. The algorithm is believed to be secure in this form.



```javascript

const encrypted = CryptoJS.TripleDES.encrypt("Message", "5ecret").toString();

​

const decrypted = CryptoJS.TripleDES.decrypt(encrypted, "5ecret").toString(CryptoJS.enc.Utf8);

```



### RC4

RC4 is a widely-used stream cipher. It's used in popular protocols such as SSL and WEP. Although remarkable for its simplicity and speed, the algorithm's history doesn't inspire confidence in its security.



```javascript

const encrypted = CryptoJS.RC4.encrypt("Message", "5ecret").toString();

​

const decrypted = CryptoJS.RC4.decrypt(encrypted, "5ecret").toString(CryptoJS.enc.Utf8);

```



### RC4Drop

It was discovered that the first few bytes of keystream are strongly non-random and leak information about the key. We can defend against this attack by discarding the initial portion of the keystream. This modified algorithm is traditionally called RC4-Drop.



```javascript

const encrypted = CryptoJS.RC4Drop.encrypt("Message", "5ecret").toString();

​

const decrypted = CryptoJS.RC4Drop.decrypt(encrypted, "5ecret").toString(CryptoJS.enc.Utf8);

```



### Rabbit

Rabbit is a high-performance stream cipher and a finalist in the eSTREAM Portfolio. It is one of the four designs selected after a 3 1/2-year process where 22 designs were evaluated.



```javascript

const encrypted = CryptoJS.Rabbit.encrypt("Message", "5ecret").toString();

​

const decrypted = CryptoJS.Rabbit.decrypt(encrypted, "5ecret").toString(CryptoJS.enc.Utf8);

```



## PBKDF2

PBKDF2 is a password-based key derivation function. In many applications of cryptography, user security is ultimately dependent on a password, and because a password usually can't be used directly as a cryptographic key, some processing is required.



```javascript

const salt = CryptoJS.lib.WordArray.random(128 / 8);

const key128Bits = CryptoJS.PBKDF2("Secret Passphrase", salt, {

  keySize: 128 / 32

}).toString();



const key256Bits = CryptoJS.PBKDF2("Secret Passphrase", salt, {

  keySize: 256 / 32

}).toString();



const key512Bits = CryptoJS.PBKDF2("Secret Passphrase", salt, {

  keySize: 512 / 32

}).toString();



const key512Bits1000Iterations = CryptoJS.PBKDF2("Secret Passphrase", salt, {

  keySize: 512 / 32,

  iterations: 1000

}).toString();

```
