Password Protecting a CD

[mrstuff68]

Is it possible to password protect a cd? If so how do i do this, and what program do i use. I currently have Roxio Easy Cd 5.

Not that i know of!

You could make an autorun that asks for a password i spose and spits the cd out if incorrect!

[sail3005]

i don't think you can. even if you do the autorun, the user could just disable autorun.

[Beacon]

Yep thats what i thought!
You could check if autorun was disabled somehow!

Well you could just password protect all files on your cd?

you could put the entire disc contents in a zip with a password, then autorun shells a zipper which is on the cd, but not in the zip. the zipper unzips the zip when given the password

that is the most fool proof way. use a program called PGP to encrypt them, that would work well.

CRC (cycle redundacy check) probably the closest you will get. It makes it so files know when their being copied and change of few lines in their code so it wont work properly.

An example of this is Diablo 2, it burns fine, but then it wont work without some sort of crack.

PGP is not designed to encrypt large volume of data, and will not be suitable in this calse also as PGP is private key algorithm it will be extremely slower (about 1000 times slower then conventional algorithm like DES and AES).

There are commercially available protection scheme available(SafeDisc) but the are too expensive and even those have been caracked already.

I would go with something along the line of what MarkMan said. It also depends on what types of files you are trying to protect, it will be easier if its an silgle exe(packed).

If you wanna be insane, you could invent your own filing system (i.e., something like FAT32, NTFS, HFS, etc.) and write your own drivers and burning utility to support it. That would give you complete control, but you'd have to have a lot of free time to do it.

Yes i was thinking something similar. I was thinking of writing my own file format. Basically it will be pretty similar to how Win XP treats a zip archive. When you double click on the archive it will check if its password protected if so then allow the user to view the content other wise through a password box. Havent really thought about it that much due to lack of time.
