comment Do I need two keys for AES CBC and HMAC or can I use the same key for both operations?
In a higher level API is easier to avoid mistakes, since they take care of the low-level stuff. The reason for not using SHA-256 is in the link provided in the answer, but in short: it's too fast, which makes brute force attacks faster. Furthermore its output is limited to 256 bits and you may need more for generating both keys.

You shouldn't be able to break it, the CPU doesn't "leave a pattern".
