A colleague suggested creating a random key via the following command:
tr -dc A-Za-z0-9_\!\@\#\$\%\^\&\*\(\)-+= < /dev/urandom | head -c 32 | xargs
It gave me the error:
tr: Illegal byte sequence
I'm concerned that I do not have /dev/urandom
on my system. I tried googling to figure out how to install this file, but I have come up empty. I tried locate urandom
and also came up empty. (well actually, it found the man page, but that doesn't help)
How do I make urandom
available on my Mac OSX system? (Lion)

Based on the error message that you get, I don't think /dev/urandom is the problem. If it were, I'd expect an error like "no such file or directory".
I searched for the error message you got and found this, which seems like it might be relevant to your issue: http://nerdbynature.de/s9y/2010/04/11/tr-Illegal-byte-sequence
Basically, specify the locale by prepending the
tr
command withLC_CTYPE=C
