3 | NAME | ||
4 | ssh-rand-helper - random number gatherer for OpenSSH | ||
5 | |||
6 | SYNOPSIS | ||
7 | ssh-rand-hlper [-vxXh] [-b bytes] | ||
8 | |||
9 | DESCRIPTION | ||
10 | ssh-rand-helper is a small helper program used by ssh(1), ssh-add(1), | ||
11 | ssh-agent(1), ssh-keygen(1), ssh-keyscan(1) and sshd(8) to gather random | ||
12 | numbers of cryptographic quality if the openssl(4) library has not been | ||
13 | configured to provide them itself. | ||
14 | |||
15 | Normally ssh-rand-helper will generate a strong random seed and provide | ||
16 | it to the calling program via standard output. If standard output is a | ||
17 | tty, ssh-rand-helper will instead print the seed in hexidecimal format | ||
18 | unless told otherwise. | ||
19 | |||
20 | ssh-rand-helper will by default gather random numbers from the system | ||
21 | commands listed in /etc/ssh/ssh_prng_cmds. The output of each of the | ||
22 | commands listed will be hashed and used to generate a random seed for the | ||
23 | calling program. ssh-rand-helper will also store seed files in | ||
24 | ~/.ssh/prng_seed between executions. | ||
25 | |||
26 | Alternately, ssh-rand-helper may be configured at build time to collect | ||
27 | random numbers from a EGD/PRNGd server via a unix domain or localhost tcp | ||
28 | socket. | ||
29 | |||
30 | This program is not intended to be run by the end-user, so the few com- | ||
31 | mandline options are for debugging purposes only. | ||
32 | |||
33 | -b bytes | ||
34 | Specify the number of random bytes to include in the output. | ||
35 | |||
36 | -x Output a hexidecimal instead of a binary seed. | ||
37 | |||
38 | -X Force output of a binary seed, even if standard output is a tty | ||
39 | |||
40 | -v Turn on debugging message. Multiple -v options will increase the | ||
41 | debugging level. | ||
42 | |||
43 | -h Display a summary of options. | ||
