...
Other plugins, such as the CryptoTransientPrincipalConnector or ResolverCryptoTransientIDAttributeDefinition, require injection of an instance of this object. You will typically configure the object by adding a <bean> declaration to a Spring configuration file. You can modify internal.xml directly, but it's typically better to create your own extension file and add it to web.xml in the contextConfigLocation context parameter.

The SunPKCS11 JCE provider that is installed by default on the Solaris JVM appears to be incompatible with this code. To use it, modify the default provider list by editing $JAVA_HOME/jre/lib/security/java.security. |
Keystore
The object usually gets its cryptographic key(s) from a special kind of keystore of type "JCEKS" designed for symmetric keys. Creating one requires overriding the keystore type when using the keytool command:
| Code Block |
|---|
keytool -genseckey -keystore secret.jks -storetype JCEKS -alias secretnameid -keyalg AES -keysize 128 |
Once you create the keystore file, copy it to all the IdP servers in your cluster.
Using larger key sizes typically requires the "full-strength" JCE policy files, and seems to cause problems for some sites. Using AES-128 generates fairly reasonable sizes of data (256 bytes) and is strong enough at least for the moment.

macKey(SecretKey)- Allows the HMAC key to be set directly.
