Supported Cipher Suites

A cipher suite is a collection of security algorithms that determine precisely how an SSL/TLS connection is implemented.

For example, the SSL/TLS protocol mandates that messages be signed using a message digest algorithm. The choice of digest algorithm, however, is determined by the particular cipher suite being used for the connection. Typically, an application can choose either the MD5 or the SHA digest algorithm.

The cipher suites available for SSL/TLS security in Fuse Services Framework depend on the particular JSSE provider that is specified on the endpoint.

The Java Cryptography Extension (JCE) and the Java Secure Socket Extension (JSSE) constitute a pluggable framework that allows you to replace the Java security implementation with arbitrary third-party toolkits, known as security providers.

In practice, the security features of Fuse Services Framework have been tested only with SUN’s JSSE provider, which is named SunJSSE.

Hence, the SSL/TLS implementation and the list of available cipher suites in Fuse Services Framework are effectively determined by what is available from SUN’s JSSE provider.

The following cipher suites are supported by SUN’s JSSE provider in the J2SE 1.5.0 Java development kit (see also Appendix A of SUN’s JSSE Reference Guide):
