Inkjar 1.1 is like 1.0 except it now runs on Java 5.0 and also 1.3, not just 1.4.
Inkjar offers a way to send someone a secret message, encrypted with an industry leading cryptography algorithm, without the receiver having to install any software at all. The data of the message and the software are bundled into one Java jar file. Just double click the jar file. You can even save it and pass on another Inkjar to someone else.
