# generate random password 15 characters long # Generate a random hex password 20 characters long. The input from /dev/urandom
# See: https://unix.stackexchange.com/questions/230673/how-to-generate-a-random-string # does not need to be any particular length due to SHA-2 256's design (for exam-
# ple, the "avalanche" effect and the input padding), so I just read 1 byte with
# dd. Some sites (see below) recommend using a minimum of 20 characters for hex
# passwords.
