(JavaScript) Encrypt / Decrypt Secure Strings

See more Encryption Examples

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Load the secure string with some text.
var secStr1 = new CkSecureString();
success = secStr1.LoadFile("qa_data/txt/helloWorld.txt","utf-8");
if (success !== true) {
    console.log("Failed to load helloWorld.txt");
    return;
}

var crypt = new CkCrypt2();

crypt.CryptAlgorithm = "aes";
crypt.CipherMode = "cbc";
crypt.KeyLength = 128;
crypt.SetEncodedKey("000102030405060708090A0B0C0D0E0F","hex");
crypt.SetEncodedIV("000102030405060708090A0B0C0D0E0F","hex");
crypt.EncodingMode = "base64";

// Return the base64 encoded encrypted contents of secStr1.
var encryptedStr = crypt.EncryptSecureENC(secStr1);
console.log("Encrypted string: " + encryptedStr);

// Output:
// Encrypted string: qiq+IFhcjTkEIkZyf31V/g==

// Decrypt to secStr2:
var secStr2 = new CkSecureString();
crypt.DecryptSecureENC(encryptedStr,secStr2);

// Access the contents of secStr2
console.log("Decrypted string: " + secStr2.Access());

// Output:
// Decrypted string: Hello World!
