fs.js:165 Uncaught NodeError: Callback must be a function

[thiagorova]

Hi! first of all, thanks!

I'm using Node 86. I'm not quite sure at which version this started happening, but not fs.unlink is obligated to have a callback. This is causing an error:

fs.js:165 Uncaught NodeError: Callback must be a function
   at ReadStream.<anonymous> (/.../file-encryptor.js:70:10)

which makes your decrypting package fail. I can look into this if you like.
Thanks again!
