VB, mySQL, PHP - Encryption

Currently I am passing unencrypted data between a VB front end and a mySQL/PHP backend via POST and URLEncode. This means any data I send is in plain text: "POST /xyz/[login to view URL] HTTP/1.1" This is really bad security and I want to encrypt the stream (without using SSL) using blowfish. I can use blowfish to encrypt the data on the VB side, I need someone to write me a PHP script to decode the blowfish encryption so that it works server side and ensure the upload and translation works correctly. The goal is to ensure that no plain text is sent across the internet. Please note SSL is NOT an option. ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
