NAME

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

SYNOPSIS

     gnunet-revocation [-t KEY | --test=KEY] [-e EPOCHS | --epochs=EPOCHS]
                       [-R NAME | --revoke=NAME] [-p | --perform] [-f NAME | --filename=NAME]
                       [-c FILENAME, --config=FILENAME] [-h | --help]
                       [-L LOGLEVEL | --loglevel=LOGLEVEL] [-v | --version]

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     gnunet-revocation can be used to verify if a key has been revoked, to create a revocation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 they 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.

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             Check if the given KEY (ASCII-encoded public key required) has been revoked.

     -e EPOCHS | --epochs=EPOCHS
             Number of epochs for which the revocation should be valid (default: 1)

     -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.
