Using AES / CBC / PKCS5Padding / IV Encryption In ColdFusion And Decrypting Values In Node.js

The other day, I talked about the problems that we ran into when using default AES (Advanced Encryption Standard) encryption settings in ColdFusion and then trying to decrypt those values in Node.js. It was a bit sticky trying to figure out what the default feedback mode was (it was ECB) and how to deal with an empty initialization vector (IV).
