While the Java applets shown in these pages are useful, they have one significant drawback:
For some uses, this doesn't matter terribly much, but when you're trying to enter a fairly large plaintext or ciphertext into some of these applets, it's much too painful to have to manually type it.
So, here is how to download the Java code, so that you can run then as Java applications, and avoid the restrictions imposed on applets.
All the Java code is stored in a single executable file, Security.jar . The link to the left allows you to download this file to your own computer.
Note: You do not have to have install privileges on your machine in order to download and run this. It will work as long as you download it to a directory to which you have access (on your P: drive on Rivier machines), and as long as you have a suitably recent Java environment on your machine.
In Internet Explorer, you should be able to simply click on that link to open it. If you have an appropriate configuration on your machine, it should tell you that the file is an Executable jar file, and ask whether you wish to open it or save it.
In Internet Explorer, you can also choose to right-click on the above link, and then select the "Save Target as..." option to save the file on your machine.
If you have a recent Java Environment installed, your machine should be configured to run such a file (using the java.exe program -- otherwise known as your JVM -- in your Java environment) whenever you double-click it.
When you run this executable jar file, you should see the following:
and you can click on each of the buttons to bring up the corresponding tool.
In fact, you can bring up more than one of the tools at a time.
If you don't see the above when you try to execute the jar file, it's possible that you aren't configured to automatically invoke the appropriate JVM (java.exe) to run such an executable jar file. In this case try doing the following (on a Windows system):
