I needed a nice random password, something that is fairly strong. Enter /dev/urandom and md5:
$ head /dev/urandom | md5

Obviously, that’s not the password I used.
Problems with this method: if you don’t write it down, or save it somewhere, you will not be able to get it back. Second, it only uses a small subset of the ascii codeset - 0123456789abcdef. I’ve tried to come up with something that converts this to ascii, but I’m still working on it. You’d also likely want to ignore 8-bit values, as these can be extended characters. If you ever needed to type this in, it’s sometimes hard to do.
The big advantage is that this is a totally random method, and you won’t get the same code twice.
This would be good for WEP keys, actually.
