NAME

       gnunet-vectorproduct - compute a vectorproduct

SYNOPSIS

       gnunet-vectorproduct [options]

DESCRIPTION

       gnunet-vectorproduct  enables  you  to  compute a vectorproduct across two peers Alice and
       Bob.

       A client can issue one of two messages to its service:

       1   A request to compute a vectorproduct with another peer (Alice)
       2   Elements to support a peer in computing a vectorproduct (Bob)

       Both requests must share the same SID, which can be an arbitrary  string  identifying  the
       session.  SIDs  should  be unique, however it is sufficient to guarantee the uniqueness of
       the tupel element count and session ID.

       Alice´s client must supply the ASCII encoded peer ID of bob´s service, it will  internally
       be  checked  by  the  client for validity. Invalid values here result in the client or the
       service failing the session.

       Elements are handed over as signed decimal integers, the element count supplied  by  Alice
       and  Bob  must  match. Alice can also supply a mask for these values to her service, which
       allows partial vector products to be computed across the vector. Elements can be masked by
       setting  their  the  corresponding mask element to zero, any other value means the element
       will not be masked. Alice´s client will  also  mask  all  0-values  to  avoid  information
       leakage to Bob.

       The  protocol by definition relies on Alice and Bob being benign, thus Bob can arbitrarily
       falsify his information. Both peers collaborate to achieve a correct result.

OPTIONS

       -e ELEMENTS, --elements=ELEMENTS
              The element-vector the vectorproduct should be  computed  over  in  signed  decimal
              form, eg:

       -m MASK, --mask=MASK
              Elements  in  the vector can be masked. There must be at least two elements left in
              the vector to compute a vectorproduct. Non-Zero values indicate an element  is  not
              maskes.

       -k KEY, --key=KEY
              The  session  key,  a  shared string of arbitrary length from which the SID will be
              generated

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

       -p PEERID, --peer=PEERID
              The remote peer´s ASCII-armored gnunet-peer ID as  output  by  gnunet-peerinfo.  If
              this option is not given, the peer will take the Bob´s role.

       -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.
