Let's look at each of the commands: dd if=/dev/urandom bs=256 count=1 2> /dev/null This will read a single 256 byte block from /dev/urandom, a cryptographically secure random source. The problem starts here, and is related to this 256 byte limit. In fact, you do not even need to use dd here.
WebCryptographically secure generators are generators that are strongly believed to be very difficult to predict, in part because they have received considerable scrutiny from the cryptographic community and no one has found a good way to break them. One such example is arc4random on OS X, iOS, and various BSD Unix variants, but there are many …
