java.lang.Objectorg.apache.myfaces.shared.util.StateUtils
public final class StateUtils
Handles encryption, serialization, compression and encoding.
The secret is interpretted as base 64 encoded. 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.
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 .
