… well, literally… or pseudo literally?

To generate 128 bits of pseudo-randomness:

dd if=/dev/urandom bs=16 count=1 2>/dev/null| hexdump |awk '{$1=""; printf("%s", $0)}' | sed 's/ //g'

Block size 16 = 16 bytes… do that once (count=1); that’s 16 bytes * 8 bits/byte = 128 bits. I’ve been using this in scripts lately, like “foo=$(…)”.

Sorry, the comment form is closed at this time.
