How Do I Use Rsa Between Server And Gwt Client?

I want to encrypt data between a Java Server backend and a GWT Client. On the GWT client I use the sbn.js library. It works very fast and is much faster that gwt-crypto. Here is H

Solution 1:

RSA can only encrypt data blocks that are shorter than the key length.

There are many topics i SO for this ex : how to use RSA to encrypt files (huge data) in C#

where to go next ? Javascript <-> Java AES
