How is a private key created for bitcoin?

How is a private key created for Bitcoin? Generate a random set of data. For our purposes of Bitcoin, we need a cryptographically secure number generator to generate our number. Convert random data to 256-bit number. Now that we have a random set of data, we can use SHA256 to convert our random set of data into 256 Verify Number. Add version number. Add 32 bit checksum.
