Java JRE policy key size 256 bits

[gregos22]

Hello

On a default JDK installation, encryption algorithm is limited to 128 bit key size. In order to perform 256-bit encryption, I need to install Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files.
It's only 2 jar files to put in java_installation_directory/jre/lib/security

Available on Oracle site :
http://download.oracle.com/otn-pub/java/jce/7/UnlimitedJCEPolicyJDK7.zip

Without root rights, I can't install it
