Comment (by cypherpunks):
The attached patch uses nsIRandomGenerator, which calls
PK11_GenerateRandom. It generates more random results than rand() and is
adapted from an existing comm-central implementation in bug
https://bugzilla.mozilla.org/show_bug.cgi?id=902580
Reviewers should note the rand_buf and character count to see if any
tweaking needs to be done for additional defense.
