Hi there, I have a simple client/server program that I wrote and I know wish to add an encryption layer to the program which will encrypt a file before sending to the server. Once it reaches the server the server will decrypt it and store it. Do I need to download JCE or similar to use DES in java.? Has anyone got any pointers or advice about this? Thanks
Well everything depends on what you want to do ! If you prefere to have things encrypted but there is really a need to KISS (Keep It Simple & Stupid) why not simply use HTTPS to post your text ? I would suggest you to look at the tutorial on java world about a simple HTTPS client !
