Project Description:
Hi, I need very simple designed php website which can work behind proxy (maximum one image as a logo, no java, no javascript, no flash, just some color and text for the homepage). Users should be able to register at homepage, and then to send messages each to other. their messages should be encrypted, there are 2 possibilities for that:
1)Data compressed and encrypted in the browser before sending to server. Uses 256 bits AES.
2)server gpg encryption. server uses private and public gpg key to encrypt messages.
I prefer browser encryption but I don't want javascript because of the man in the middle attacks, if therefore it is not possible, then second option is OK (gpg encryption).
So, there should be homepage where people can register and login (index.php), then one page after people login and they can send message to the other users, it could be main.php (there should be link to the page where are listed all users, allusers.php), then sent.php, maybe config.php and maybe mysql or self destroying option for messages (after 10 minutes). of course, users should have option to delete messages, I found some tutorial on internet for making PM system but there is no option to delete messages (plus I want encryption).
The look should be similar like this, but not the same, this is just example: http://nobody.zerodays.org/wp-content/uploads/2012/02/2012-02-10_23-11-20.jpg

Hi, I am sorry but I gave up from this project and I tried to delete it but it is not possible, I think I have to pay 5 euro to be deleted but that's strange idea of owner of site. so, in this way I must inform all potential bidders about my decision.
