Android Client, Http Server, How do I know client is sending data using my app? authentication

Question

I have client/server data passing all working correctly. Text, Images, etc. My users create blog-type posts on their android device, and upload to my server.. All is done us

Answer 1

I finally got it all working, server and client two-way ssl authentication.

I used the instructions here to setup my own cert authority (ca) http://www.garex.net/apache/

I followed the commands there to generate my own ca, server and client files..

The big "GOTCHA" was that in the "create client certificate" section, the garex.net link uses a 1024 size client key. As it turns out, this was throwing the exception java.io.IOException: Wrong version of key store

To get around the above exception, I had to use only 512 sized keys.. This is done by NOT including the "1024" parameter to the openssl genrsa genkey command..

Finally I want to add a link to a tool I ended up using instead of Portecle.. I found the keytool gui program here of great help and easier to use than the portecle one - http://www.lazgosoftware.com/kse/index.html

This issue was a bit of a pain in the butt so I will keep an eye on this thread.. Feel free to reply if you run into any roadblocks..
