You can learn more detailed information about transport security using Java Secure Socket Extension (JSSE) and Java Cryptography Extension (JCE) programming interfaces. Within this topic, there is a description of the IBM® version of the Java Cryptography Extension Federal Information Processing Standard (IBMJCEFIPS).
JSSE provides the transport security for WebSphere® Application Server. JSSE provides the application programming interface (API) framework and the implementation of the APIs for Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, including functionality for data encryption, message integrity, and authentication.
JSSE APIs are integrated into the Java 2 SDK, Standard Edition (J2SDK), Version 5. The API package for JSSE APIs is javax.net.ssl.*. Documentation for using JSSE APIs can be found in the J2SE 6 API documentation that is located at http://java.sun.com/javase/6/docs/technotes/guides/security/jsse/JSSERefGuide.html.
Several JSSE providers ship with the Java 2 SDK Version 5 that comes with WebSphere Application Server. The IBMJSSE provider is used in previous WebSphere Application Server releases.
For more information on the new IBMJSSE2 provider, please review the documentation located at http://www.ibm.com/developerworks/java/jdk/security/60/.
Customizable item | Default | How to customize |
---|---|---|
X509Certificate | X509Certificate implementation from IBM | The cert.provider.x509v1 security property |
HTTPS protocol | Implementation from IBM | The java.protocol.handler.pkgs system property |
Cryptography Package Provider | IBMJSSE2 | A security.provider.n= line in security properties file. See description. |
Default keystore | None | The * javax.net.ssl.keyStore system property |
Default truststore | jssecacerts, if it exists. Otherwise, cacerts | The * javax.net.ssl.trustStore system property |
Default key manager factory | IbmX509 | The ssl.KeyManagerFactory.algorithm security property |
Default trust manager factory | IbmX509 | The ssl.TrustManagerFactory.algorithm security property |
For aspects that you can customize by setting a system property, statically set the system property by using the -D option of the Java command. You can set the system property using the administrative console, or set the system property dynamically by calling the java.lang.System.setProperty method in your code: System.setProperty(propertyName,"propertyValue").
For aspects that you can customize by setting a Java security property, statically specify a security property value in the java.security properties file. The security property is propertyName=propertyValue. Dynamically set the Java security property by calling the java.security.Security.setProperty method in your code.
The java.security properties file is located in the following directory:
profile_root/properties directory.

UseHttps.java | Demonstrates accessing an SSL or non-SSL web server using the Java protocol handler of the com.ibm.net.ssl.www.protocol class. The URL is specified with the http or https prefix. The HTML that is returned from this site is displayed. |
By configuring through the javax.net.debug system property, JSSE provides the following dynamic debug tracing: -Djavax.net.debug=true.
A
value of true turns on the trace facility, provided
that the debug version of JSSE is installed.
See the Security: Resources for learning topic for documentation references to JSSE.
Java Cryptography Extension (JCE) provides cryptographic, key and hash algorithms for WebSphere Application Server. JCE provides a framework and implementations for encryption, key generation, key agreement, and Message Authentication Code (MAC) algorithms. Support for encryption includes symmetric, asymmetric, block and stream ciphers.
For further information, see the information on JCE on the following website: http://www.ibm.com/developerworks/java/jdk/security/60/.
There is more information
documented for the JCE APIs on the http://www.ibm.com/developerworks/java/jdk/security/ website.
