commit 936a799d32c28dc8857b97a5fe90f0150a280fa4
Author: Robin McCorkell <rmccorkell at karoshi.org.uk>
Date:   Thu Jul 9 15:28:05 2015 +0100

    Replace random() and related calls with generate_random_buffer()
    
    Result: better seeded random numbers that are cryptographically secure
    (not that it matters in this case)
    
    Please let it be right this time...
