flash - FLV/SWF - video protection tool for the web-v2

i need to create a custom tool that can protect my videos i have in flash (FLV or SWF) format. The files are to be played and hosted online. No specific server requirements are needed. I need to be able to: 1) Protect the FLV or SWF or TXT file (see below) 2) Password protect? the SWF or FLV files as above 3) Lock flash files to my domain, so they could not be used outside of my server. More info: (unique key in txt file,? located next to flash file I need to play,? that must match). One text file per flash file. The txt file is encrypted with strong encryption. I create txt file that has the url info and other info we need encoded. the flash video needs to read the txt file on the server, and play or not play the video. The flash video file must be protected and encrypted, so the protection module can not be decompiled or removed bysome other software. the txt file must be encrypted online with asp utility or other web based utility. I am flexible on the language used. The flash video will be called by my asp file on asp shared hosting server. The files (FLV, SWF, txt) should not be decrypted by any available decompiling utility or unprotection utility. this is not an exe protection tool, as the files are hosted on the web server for online viewing only. the program should run under win 98 upto and including vista, and on any shared asp web hosting server.
