   Encrypt in ColdFusion

   Summary
   1. Generate a cryptographically random key with GenerateSecretKey(). Do *not* use a self generated 
      password, which is less secure. 
   2. Generate a random IV (initialization vector)][2] and decode into binary.
   3. Encrypt the plain text with AES/CBC/PKCS5Padding
*/

<cfscript>
	// Plain text to encrypt
	plainText = 'This is a plain text string';
	// Secure key produced by generateSecretKey("AES")
	base64Key = "WTq8zYcZfaWVvMncigHqwQ==";
	// Use appropriate method to decode into binary: charsetDecode, binaryDecode, etcetera
	// Important: IV values should be randomized
	binaryIV = binaryDecode("a5e72a3a083a908f32c45f3c7e3143ae", "hex");
	encryptedText = encrypt(plainText, base64Key, "AES/CBC/PKCS5Padding", "hex", binaryIV);

        // Expected result: "39EE0FE0EF686D6619BA8D55D4FC57C2AB35DDE7E692AD051F900906B0E53317"
	writeOutput( encryptedText );

   Decrypt in Node.js

   Summary
   1. Decrypt key string into binary. Use the appropriate encoding parameter to ensure the string is decoded correctly.
   2. Decrypt IV into binary, with the appropriate encoding parameter
   3. Decrypt encrypted string into binary, with the appropriate encoding parameter
   4. Decrypt the binary using cipher.createDecipheriv(algoirthm, key, iv)
   5. Convert the decrypted binary into a human readable string
