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. A cryptographically secure pseudorandom number generator (CSPRNG) or cryptographic pseudorandom number generator (CPRNG) is a pseudorandom number generator (PRNG) with properties that make it suitable for use in cryptography.
