  1. It would be even more secure if they used the last seven digits of π, as written in hexadecimal notation.

  2. This is surprisingly easy to crack. It's "0000000".

    You can append an arbitrary number of zeroes to the end of the fractional part of a real number without changing its value.

  3. @Dave H: Actually, that would change the value of pi. Is 3.1415000000 = 3.14159?

  4. Not that difficult. Just generate a 7 digit random number until one works.
