SSH-RAND-HELPER(8)          System Manager's Manual         SSH-RAND-HELPER(8)NAME     ssh-rand-helper - Random number gatherer for OpenSSHSYNOPSIS     ssh-rand-hlper [-vxXh] [-b bytes]DESCRIPTION     ssh-rand-helper is a small helper program used by ssh(1), ssh-add(1),     ssh-agent(1), ssh-keygen(1), ssh-keyscan(1) and sshd(8) to gather random     numbers of cryptographic quality if the openssl(4) library has not been     configured to provide them itself.     Normally ssh-rand-helper will generate a strong random seed and provide     it to the calling program via standard output. If standard output is a     tty, ssh-rand-helper will instead print the seed in hexidecimal format     unless told otherwise.     ssh-rand-helper will by default gather random numbers from the system     commands listed in /etc/ssh/ssh_prng_cmds.  The output of each of the     commands listed will be hashed and used to generate a random seed for the     calling program.  ssh-rand-helper will also store seed files in     ~/.ssh/prng_seed between executions.     Alternately, ssh-rand-helper may be configured at build time to collect     random numbers from a EGD/PRNGd server via a unix domain or localhost tcp     socket.     This program is not intended to be run by the end-user, so the few comM--     mandline options are for debugging purposes only.     -b bytes             Specify the number of random bytes to include in the output.     -x      Output a hexidecimal instead of a binary seed.     -X      Force output of a binary seed, even if standard output is a tty     -v      Turn on debugging message. Multiple -v options will increase the             debugging level.  -h Display a summary of options.AUTHORS     Damien Miller <djm@mindrot.org>SEE ALSO     ssh(1), ssh-add(1), ssh-keygen(1), sshd(8)BSD                             April 14, 2002                             BSD
