Setting a password on JAR

SelfExtract-Pro allows a password to be specified for a self-extracting JAR.

Passwords can be any length and contain any characters but should not be blank. Once the password is entered any self-extracting JAR subsequently created will require the user to enter the password before extracting the files. When an incorrect password is entered then the "Access denied" message is displayed and this can be altered to anything you like.

When a password is used SE-Pro scrambles the data inside the JAR so that simply unzipping the JAR won't get around having to specify the password.
