RDD(1) General Commands Manual RDD(1)
NAME
rdd – random data dump
SYNOPSIS
rdd [-i source] [-r rekeymb] [-v]
DESCRIPTION
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.
Random binary data is outputted to standard output.
The options are as follows:
-i source
Read key and IVs from source (default: /dev/urandom)
-r rekeymb
Reload the IV every rekeymb megabytes of output (default: 4).
-v Print a ‘.’ to standard error on every rekey.
EXIT STATUS
The rdd utility exits 0 on success, and >0 if an error occurs.
SEE ALSO
dd(1), random(4), random(7)
NOTES
rdd reads 32 random bytes for the initial key and 16 bytes for every
rekeying from the random source. Setting rekeymb to -1 never rekeys.
This implementation passed dieharder 3.31.1 "-a" and PractRand/RNG_test
0.93 (tested up to 32 TB).
