Kony-API for Encryption and Decryption using Algorithm

Example Code :
Key :: md4 algorithm
function genhashKEY() {
    try {  
        var algorithm_key = "md5";
        var hashKEY = kony.crypto.createHash(algorithm_key, "chandrupass");
        alert("Result : " + hashKEY);   
    } catch (err) {
        alert("Error" + err);
    }
}


Output Screen : 

Example Code : 

Key :: aes algorithm 


function genAEGALGM()
{
     var algo = "aes";

    var encryptDecryptKey = kony.crypto.newKey(
        "passphrase",
        128, {
            passphrasetext: ["inputstring1"],
            subalgo: "aes",
            passphrasehashalgo: "aes"
        });

    var inputstring = "chandrupass";

    alert("Before Encrypt : " + inputstring);
    var prptobj = {
        padding: "pkcs5",
        mode: "cbc",
        initializationvector: "1234567890123456"
    };

    var myEncryptedText = kony.crypto.encrypt(
        algo,
        encryptDecryptKey,
        inputstring,
        prptobj);

    alert("ChiperText : " + JSON.stringify(myEncryptedText));

    var myClearText = kony.crypto.decrypt(
        algo,
        encryptDecryptKey,
        myEncryptedText,
        prptobj);


    alert("Original Text : " + myClearText);
}
