Use Cipheriv for counter mode of aes-256-ctr

[PRFinklemeister]

Wen I run this sample: https://github.com/chris-rock/node-crypto-examples/blob/master/crypto-buffer.js

I get this warning:

hello world
(node:25420) Warning: Use Cipheriv for counter mode of aes-256-ctr

Does this reduce the crypto security?

Yes, it does. Actually all the given examples are insecure if they use createCipher. That method has relatively recently been deprecated but it was obviously completely insecure before that.
