JXTA technology is a set of open protocols that allow any connected device on the network ranging from cell phones and wireless PDAs to PCs and servers to communicate and collaborate in a P2P manner. JXTA peers create a virtual network where any peer can interact with other peers and resources directly even when some of the peers and resources are behind firewalls and NATs or are on different network transports.

The newest version!







The 'binary' format is a general purpose JXTA ID Format. It implements Peer,
group, and pipe ID types. The remaining types are supported, but not
guarenteed (CODAT not supported at all yet).

    The DigestTool class is probably the main entry point for most developers.
    The class creates various BinaryID types with an SHA digest hashing. The
    intent is to make secure but non-random possible for ID pipes, peers,
    and peer groups. When using the utility, it is recomended tha you use
    a hash size apropriate to your address space.

    @see net.jxta.impl.id.binaryID.DigestTool

    This package supports the creation of an identifier given a binary value
    that is 0 to 255 bytes long that is encoded as Base64. The value needs to
    be a unique value so that it can be used for addressing peers, pipes, and
    groups.



    The implementation also includes the creation of a digest hash given an
    arbirary length string. This allows you to encode any type of data into
    a secure digest. The digest hash is recomended unless you are sure that
    your binary id is truely unique. Using a digest hash is also preferrable
    for situatins when you have an id that could be comprimized if known (like
    a socal security number). The digest tools also have convenience methods
    for mixing an id with a function name and a way to create a time
    limited ID.



    Note that this ID currently only allows parent peer group ID to be of
    type UUID.
