rdd - random data dump

rdd is a high-speed, cryptographically safe random data generator using the reference implementation of the eSTREAM Profile 1 SOSEMANUK stream cipher.

It is designed to fill crypto devices with random data.

This implementation passed dieharder 3.31.1 "-a" and PractRand/RNG_test 0.90 (tested up to 512 GB).

Usage

rdd [-i SOURCE] [-r REKEYMB] [-v]
   -i SOURCE     read key and IVs from SOURCE (/dev/urandom)
   -r REKEYMB    reload the IV every REKEYMB megabytes of output (4)
       -v            print a . to stderr on every rekey

Random binary data is outputted to stdout. Better don't put a terminal there. rdd reads 32 bytes for the initial key and 16 bytes for every rekeying from the random source. Setting REKEYMB to -1 never rekeys.
