How do I store symmetric encryption keys securely?

I have some files which I want to encrypt (I think it will be AES). Each file should have a different key.

What is the best way to store the encryption key? I know it shouldn't be stored in the program itself, but should I store it in a file? Then I'm worried about the security of where the file is stored.

I know about CSP - but this way only for asymmetric keys (RSA). What about symmetric keys (AES)?

If you are serious about the encryption then the key is everything. eg key under the mat story. You can get a simple hardware device that can provide the key. Someone would need physical access to the system to get the key.

Ill let you research the HW tools on offer. No plugs from me.
