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.
