NAME

       gnunet-revocation - revoke private keys (of egos) in GNUnet

SYNOPSIS

       gnunet-revocation [options]

DESCRIPTION

       gnunet-revocation can be used to verify if a key has been revoked, to create a revocation certificate for
       later revocation, to instantly revoke a key and to use a pre-generated revocation certificate to revoke a
       key.  Upon successful revocation, all peers will be informed about the invalidity of the key.  As this is
       an expensive operation, GNUnet requires the issuer of the revocation to perform  an  expensive  proof-of-
       work  computation  before  he  will be allowed to perform the revocation.  gnunet-revocation will perform
       this computation.  The computation can  be  performed  ahead  of  time,  with  the  resulting  revocation
       certificate  being stored in a file for later "instant" use.  gnunet-revocation also makes is possible to
       resume the pre-calculation of a revocation --- simply abort  a  running  proof-of-work  calculation  with
       CTRL-C,  and  the  existing revocation certificate file will contain the status of the computation.  Note
       that performing a revocation proof-of-work is deliberately VERY expensive.  Depending on  your  CPU,  the
       calculation can take days or weeks.

OPTIONS

       -t KEY, --test=KEY
              Check if the given KEY (ASCII-encoded public key required) has been revoked.

       -R NAME, --revoke=NAME
              Calculate or perform revocation for the ego with the given NAME.

       -p, --perform
              Actually  perform  the  revocation  as  soon  as  possible  (do  not  just  generate  a revocation
              certificate, use it).  Must be supplied to actually perform the revocation.

       -f NAME, --filename=NAME
              Use NAME as the name of the file that is to  contain  the  revocation  certificate.   Intermediate
              computation  results  will be stored here, as well as the final revocation certificate.  When used
              together with -p, this file will be inspected to see  if  it  contains  a  valid  certificate  for
              instant  revocation,  in  which case the revocation can be performed instantly.  If the given file
              contains anything (a valid certificate, with or without the completed proof-of-work) there  is  no
              need  to  supply  the  "-R"  option  or  to  still  have the private key of the ego to perform the
              revocation.

       -c FILENAME,  --config=FILENAME
              Use the configuration file FILENAME.

       -h, --help
              Print short help on options.

       -L LOGLEVEL, --loglevel=LOGLEVEL
              Use LOGLEVEL for logging.  Valid values are DEBUG, INFO, WARNING and ERROR.

       -v, --version
              Print GNUnet version number.
