Class Summary

Class	Description
Client	Implements the client side of the net.jini.discovery.ssl.sha256 unicast discovery format.
Server	Implements the server side of the net.jini.discovery.ssl.sha256 unicast discovery format.

Package org.apache.river.discovery.ssl.sha256 Description

net.jini.discovery.ssl.sha256 provides an extended implementation of the net.jini.discovery.ssl discovery format, specified in the Jini Discovery and Join Specification. The Client class implements the client side of the net.jini.discovery.ssl.sha256 discovery format for the unicast discovery protocol, while the Server class implements the server side of the discovery format for that protocol. Both classes are intended to be specified in a resource to configure the operation of the Discovery class, as described in the documentation for Discovery.getProtocol2(ClassLoader).

Extensions

The unicast response data sent by the lookup service, if the SHA-224 hash matches, is in the following form:

DJ.3.1.3 Unicast Responses

The table below illustrates the layout for unicast response discovery format data specified by the net.jini.discovery.plaintext discovery format. The values to encode are described in Section DJ.2.6.3, "Unicast Response Contents".

Count	Data Type	Description
1	java.lang.String	class annotation
1	java.lang.String	CertificateFactory type
1	java.lang.String	CertPath encoding
1	short	length of byte[] encoded certificates
1	byte []	encoded certificates
1	java.lang.String	unicast discovery host
1	unsigned short	unicast discovery port
1	unsigned short	group count
variable	java.lang.String	member groups
1	net.jini.io.MarshalledInstance	registrar proxy

The discovery format data consists of a contiguous series of values in the order listed above from top to bottom. Values of type String are encoded in the format specified for the writeUTF method of the java.io.DataOutput interface. Unsigned short values are encoded as if they were cast to signed short values, and then written in the format specified for the writeShort method of the java.io.DataOutput interface. The registrar proxy is written in the same format that would be produced by constructing a java.io.ObjectOutputStream, and writing to it an instance of net.jini.io.MarshalledInstance containing the marshalled registrar proxy. The number of group strings written must be equal to the group count value.

Supported Constraints

This provider supports the same constraints as the Jini extensible remote invocation (Jini ERI) SSL transport provider; these constraints are listed in the documentation for the net.jini.jeri.ssl package.

System Properties

This provider can be configured using the same system properties as those consulted by the SSL transport provider, also listed in the documentation for the net.jini.jeri.ssl package.
