A friend of mine in the IT Security profession gently suggested that I not use uuidgen to generate random passwords, especially now that I’ve posted to this blog that I intend to do that. He pointed out that uuidgen produces unique strings, not random ones. He further went on to suggest that it’s much better to use /dev/random as your source of entropy than to use /dev/urandom.

All duly noted, and applied. I’m once again changing all my passwords to be 40+ characters of random line noise.
