The security of encryption is partially dependent on the size of the encryption key, measured in bits (the basic unit for information). A bit can have exactly one out of two possible values 0 or 1 so two possible (2¹) outcomes. And two bits can have four (2²) outcomes: 01, 11, 00, 10. So three bits can have eight (2³) outcomes: 000, 001, 010, 011, 100, 101, 110, or 111. RSA-1024 is a very common encryption method being used today, and uses a key size of 1024 bits.

How many different RSA-1024 keys are there? (please use a calculator) (5 points)

If your computer can generate one million of these keys every second, how long would it take to create every possible RSA-1024 key? (5 points)

If every human on earth (7 billion) each had a million computers working in perfect unison like yours above, how long would it take? (5 points)
