What is the security difference between J1K Ultra-Secure and J1K Mobile?
The Ultra-Secure version is slightly more secure, although both are extremely secure. In fact, as long as our top-notch server administrators do their job correctly, the security level is essentially the same. The technical difference between the two versions is this: With Ultra-Secure, a Java Applet is run on your client computer, and your personal Just1Key passphrase is never transmitted off that machine — all decryption happens locally.
