java.lang.Objectorg.apache.myfaces.shared_impl.util.StateUtils
public final class StateUtils
This Class exposes a handful of methods related to encryption, compression and serialization.
To enable encryption, a secret must be provided. StateUtils looks first for the org.apache.myfaces.SECRET init param. If a secret cannot be located, encryption is not used.
All parameters are interpretted as base 64 encoded keys. In other words, if your secret is "76543210", you would put "NzY1NDMyMTA=" in the deployment descriptor. This is needed so that key values are not limited to just values composed of printable characters.
If you are using CBC mode encryption, you must specify an initialization vector. StateUtils will throw an exception otherwise.
If you are using the AES algorithm and getting a SecurityException complaining about keysize, you most likely need to get the unlimited strength jurisdiction policy files from a place like http://java.sun.com/j2se/1.4.2/download.html .
