You can use a source like www.random.org as a source of random
characters, but I recommend using something you control physically like
dice, coin tosses, a bingo cage, whatever. Do NOT use a random number
generator built into a programming language, unless it is specifically
designed for secure number generation, like the one in GnuPG,
Microsoft's CryptoAPI, or /dev/random on Linux.
