NAME

       ovs-pki - OpenFlow public key infrastructure management utility

SYNOPSIS

       Each command takes the form:

       ovs-pki [options] command [args]

       The implemented commands and their arguments are:
       ovs-pki init
       ovs-pki req name
       ovs-pki sign name [type]
       ovs-pki req+sign name [type]
       ovs-pki verify name [type]
       ovs-pki fingerprint file
       ovs-pki self-sign name

       Each type above is a certificate type, either switch (default) or controller.

       The available options are:
       [-k type | --key=type]
       [-B nbits | --bits=nbits]
       [-D file | --dsaparam=file]
       [-b | --batch]
       [-f | --force]
       [-d dir | --dir=dir]
       [-l file | --log=file]
       [-h | --help]

       Some options do not apply to every command.

DESCRIPTION

       The ovs-pki program sets up and manages a public key infrastructure for use with OpenFlow.
       It is intended to be a simple interface for organizations that do not have an  established
       public  key  infrastructure.   Other PKI tools can substitute for or supplement the use of
       ovs-pki.

       ovs-pki uses openssl(1) for certificate management and key generation.

OFFLINE COMMANDS

       The following ovs-pki commands support manual PKI administration:

       init   Initializes a new  PKI  (by  default  in  directory  /var/lib/openvswitch/pki)  and
              populates it with a pair of certificate authorities for controllers and switches.

              This  command  should  ideally  be run on a high-security machine separate from any
              OpenFlow   controller   or   switch,   called   the   CA   machine.    The    files
              pki/controllerca/cacert.pem  and pki/switchca/cacert.pem that it produces will need
              to be copied over to the OpenFlow switches and  controllers,  respectively.   Their
              contents may safely be made public.

              By  default,  ovs-pki  generates  2048-bit  RSA keys.  The -B or --bits option (see
              below) may be used to override the key length.  The -k dsa or --key=dsa option  may
              be  used  to  use  DSA  in place of RSA.  If DSA is selected, the dsaparam.pem file
              generated in the new PKI hierarchy must be copied to any machine on which  the  req
              command (see below) will be executed.  Its contents may safely be made public.

              Other   files  generated  by  init  may  remain  on  the  CA  machine.   The  files
              pki/controllerca/private/cakey.pem    and    pki/switchca/private/cakey.pem    have
              particularly sensitive contents that should not be exposed.

       req name
              Generates  a  new  private key named name-privkey.pem and corresponding certificate
              request named name-req.pem.  The private key can be intended for use by a switch or
              a controller.

              This  command  should  ideally be run on the switch or controller that will use the
              private key to identify itself.  The file name-req.pem must be  copied  to  the  CA
              machine for signing with the sign command (below).

              This command will output a fingerprint to stdout as its final step.  Write down the
              fingerprint and take it to the CA machine before continuing with the sign step.

              When RSA keys are in use (as is the default), req, unlike  the  rest  of  ovs-pki's
              commands,  does not need access to a PKI hierarchy created by ovs-pki init.  The -B
              or --bits option (see below) may be used to specify  the  number  of  bits  in  the
              generated RSA key.

              When  DSA  keys  are  used  (as  specified with --key=dsa), req needs access to the
              dsaparam.pem file created as part of the PKI hierarchy (but not to other  files  in
              that     tree).     By    default,    ovs-pki    looks    for    this    file    in
              /var/lib/openvswitch/pki/dsaparam.pem, but the -D or --dsaparam option (see  below)
              may be used to specify an alternate location.

              name-privkey.pem  has  sensitive contents that should not be exposed.  name-req.pem
              may be safely made public.

       sign name [type]
              Signs the certificate request named name-req.pem that was produced in the  previous
              step,  producing  a certificate named name-cert.pem.  type, either switch (default)
              or controller, indicates the use for which the key is being certified.

              This command must be run on the CA machine.

              The command will output a fingerprint to stdout and request that you verify that it
              is  the  same fingerprint output by the req command.  This ensures that the request
              being signed is the same one produced by req.  (The -b or --batch option suppresses
              the verification step.)

              The  file name-cert.pem will need to be copied back to the switch or controller for
              which it is intended.  Its contents may safely be made public.

       req+sign name [type]
              Combines the req and sign commands into a single step,  outputting  all  the  files
              produced  by  each.   The  name-privkey.pem  and name-cert.pem files must be copied
              securely to the switch or controller.  name-privkey.pem has sensitive contents  and
              must  not  be  exposed  in  transit.   Afterward,  it should be deleted from the CA
              machine.

              This combined method is, theoretically,  less  secure  than  the  individual  steps
              performed  separately  on  two  different  machines,  because  there  is additional
              potential for exposure of the private key.  However, it is also more convenient.

       verify name [type]
              Verifies that name-cert.pem is a valid certificate  for  the  given  type  of  use,
              either  switch  (default) or controller.  If the certificate is valid for this use,
              it prints the message ``name-cert.pem: OK''; otherwise, it prints an error message.

       fingerprint file
              Prints the fingerprint for file.  If file is a certificate, then this is the  SHA-1
              digest  of  the  DER encoded version of the certificate; otherwise, it is the SHA-1
              digest of the entire file.

       self-sign name
              Signs  the  certificate  request  named  name-req.pem   using   the   private   key
              name-privkey.pem,  producing  a  self-signed  certificate named name-cert.pem.  The
              input files should have been produced with ovs-pki req.

              Some controllers accept such self-signed certificates.

OPTIONS

       -k type
       --key=type
              For the init command, sets the  public  key  algorithm  to  use  for  the  new  PKI
              hierarchy.  For the req and req+sign commands, sets the public key algorithm to use
              for the key to be generated, which must match the value specified  on  init.   With
              other commands, the value has no effect.

              The type may be rsa (the default) or dsa.

       -B nbits
       --bits=nbits
              Sets the number of bits in the key to be generated.  When RSA keys are in use, this
              option affects only the init, req, and req+sign commands, and the same value should
              be  given  each  time.  With DSA keys are in use, this option affects only the init
              command.

              The value must be at least 1024.  The default is 2048.

       -D file
       --dsaparam=file
              Specifies an alternate location for the dsaparam.pem file required by the  req  and
              req+sign commands.  This option affects only these commands, and only when DSA keys
              are used.

              The default is dsaparam.pem under the PKI hierarchy.

       -b
       --batch
              Suppresses the interactive verification of fingerprints that the  sign  command  by
              default requires.

       -d dir
       --dir=dir
              Specifies  the  location  of the PKI hierarchy to be used or created by the command
              (default: /var/lib/openvswitch/pki).  All commands, except req, need  access  to  a
              PKI hierarchy.

       -f
       --force
              By  default, ovs-pki will not overwrite existing files or directories.  This option
              overrides this behavior.

       -l file
       --log=file
              Sets the log file to file.  Default: /var/log/openvswitch/ovs-pki.log.

       -h
       --help Prints a help usage message and exits.
