pollinate(1)                                pollinate                                pollinate(1)

NAME
       pollinate - an Entropy-as-a-Service client

SYNOPSIS
       pollinate  [-c|--curl-opts  CURL_OPTS] [-d|--device DEVICE] [-i|--insecure] [-n|--no-chal-
       lenge] [-r|--reseed] [-s|--server SERVER1 [-s|--server SERVER2] ...]

DESCRIPTION
       pollinate is an entropy as a service client.  It will fetch a random seed from one or more
       remote  servers,  and  feed  those into a (pseudo) random number generator.  This is often
       useful in cloud and virtual machine environments with limited sources of entropy.

OPTIONS
       -b|--binary
              rather than producing hex text sha512sum(1) output, convert  each  two  hex  digits
              into a byte of binary data

       -c|--curl-opts CURL_OPTS
              options to pass through to curl(1)

       -d|--device DEVICE
              device to seed (default is /dev/urandom); note, you can use - to print to stdout

       -n|--no-challenge
              disable  the challenge/response portion of the protocol; this enables a compatibil-
              ity mode to speak to any entropy server, like random.org or news.google.com

       -i|--insecure
              ignore SSL/TLS certificate errors (use of this option is highly discouraged)

       -p|--pool SERVER
              remote pollen(8) server pool to interact with; this option can be specified  multi-
              ple times to interact with multiple servers in a pool

       -r|--reseed
              by  default,  pollinate  technically only needs to run successfully once ever; this
              option should be used if someone wants run more than once, and re-seed the PRNG

       -s|--server SERVER
              remote pollen(8) server to interact with; if this option is used, the pool  is  ig-
              nored, and only a single server is used

       --strict
              handle network errors strictly and exit non-zero for any network error encountered,
              otherwise default is to warn

       -t|--testing
              test communications with the pollen(8) server; note that  this  will  NOT  actually
              seed  your PRNG, but only verify that the local client can communicate with the re-
              mote servers; note that this option forces DEVICE to stdout

       -q|--quiet
              silence any log messages

       -w|--wait WAIT
              time in seconds you're willing to wait for a response from the server,  uses  time-
              out(1)

          --print-user-agent
              Print the user-agent that is used and exit immediately.
