Example 1: The following example uses aes function.

            <script type="text/javascript" src="http://cryptojs.altervista.org/api/functions_cryptography.js"></script>
            <script type="text/javascript">

            var Crypt = new Crypt();  // constructor

            /*** encrypt */
            var ciphertext = Crypt.AES.encrypt("plaintext");
            // XluzvcUwZFU=3MD2vMz8PHySPJlKZiWjJg==1Gv6n6Tv8azr

            /*** decrypt */
            var plaintext  = Crypt.AES.decrypt(ciphertext);

            </script>

Example 2: The following example uses aes function with passphrase.

            <script type="text/javascript" src="http://cryptojs.altervista.org/api/functions_cryptography.js"></script>
            <script type="text/javascript">

            var Crypt = new Crypt();  // constructor

            /*** encrypt */
            var ciphertext = Crypt.AES.encrypt("plaintext", "Secret Passphrase");
            // H3fAh9bppeg=xuHy8woEtOfYYI18tLM76A==BKUvKCztSNl8

            /*** decrypt */
            var plaintext  = Crypt.AES.decrypt(ciphertext, "Secret Passphrase");

            </script>

The modes of operation currently available are:

ECB
CBC
CFB
OFB (the default)
CTR

And the padding schemes currently available are:

iso7816 (the default)
ansix923
iso10126
pkcs7
ZeroPadding
NoPadding

Example 3: The following example uses hash functions (test).

            <script type="text/javascript" src="http://cryptojs.altervista.org/api/functions_cryptography.js"></script>
            <script type="text/javascript">

            var Crypt = new Crypt();  // constructor

            /*** MD5 */  
            var digest_md5 = Crypt.HASH.md5("message"); 
            // 78e731027d8fd50ed642340b7c9a63b3

            /*** SHA1 */  
            var digest_sha1 = Crypt.HASH.sha1("message"); 
            // 6f9b9af3cd6e8b8a73c2cdced37fe9f59226e27d

            /*** SHA224 */  
            var digest_sha224 = Crypt.HASH.sha224("message");
            // ff51ddfabb180148583ba6ac23483acd2d049e7c4fdba6a891419320

            /*** SHA256 */  
            var digest_sha256 = Crypt.HASH.sha256("message");
            // ab530a13e45914982b79f9b7e3fba994cfd1f3fb22f71cea1afbf02b460c6d1d

            /*** SHA384 */  
            var digest_sha384 = Crypt.HASH.sha384("message");
            // 353eb7516a27ef92e96d1a319712d84b902eaa828819e53a8b09af7028103a9978ba8feb6161e33c3619c5da4c4666a5

            /*** SHA512 */  
            var digest_sha512 = Crypt.HASH.sha512("message");
            // f8daf57a3347cc4d6b9d575b31fe6077e2cb487f60a96233c08cb479dbf31538cc915ec6d48bdbaa96ddc1a16db4f4f96f37276cfcb3510b8246241770d5952c
