I am curious of how the private key was generated randomly. Usually PGP systems will use mouse movement or such. If it was generated without user interface and used the cpu algorithm then it is only pseudorandom.

There are several different types of Bitcoin clients. Header-only clients like MultiBit trust that the majority of mining power is honest for the purposes of enforcing network rules such as the 21 million BTC limit. Full clients do not trust miners in this way.

Afaik bitcoin sues OpenSSL for creating keys, but I don't know how OpenSSL handles their randomizing algorithm.

On unix systems, it appears OpenSSL uses /dev/random or /dev/urandom for [pseudo] random number generation.  It looks like it does something a little different on windows.
