A perfectly encrypted CD *should* look blank. Unless you enter the correct password, or you cannot use the CD's content.

Both Bestcrypt and Scramdisk are good softwares. But the drawback is that even you have the password, if you don't have the software installed on your PC, still you cannot utilize the encrypted CD.

"Encryption for CD-ROM" is another very good software. It doesn't require the program itself for decryption. However, one main disadvantage is that the encryted files are "visible" to all outsiders. That is, even you don't have the password, you can still see the filenames and sizes of the files,etc. , although you cannot use them.

You may now wonder, " As there is no program pre-installed, and the CD looks blank, how do you think you can enter your password? "

Well, actually it is not difficult, I will try to list out 2 methods:

1. When the end-user insert the CD, a pop-up window will appear on the screen( sort of like autorun), it requires the user to enter the password. If the password is correct, then he can read the original CD (i.e, decrypted). If the password is wrong, then all he can read is a blank disk. He may need to re-insert the CD in order the activate the pop-up again.

2. When the end-user insert the CD, all he can read is a single file. If he execute the file, a pop-up window will appear on the screen, it requires the user to enter the password. If the password is correct, then he can read the original CD (i.e, decrypted). If the password is wrong, then all he can read is the single file. He can repeat this procedure again and again until he enter the right password.

So, my question is: Is there any very very good encryption program out there that makes a near-perfect encryption for CD? Thanks.

Why would you need to encrypt a CD? Can't you just lock it in a box/safe?

Hey, me too, but only because I am so pale from being a programmer and all that I fear the sun could kill me nowadays.. Sort of a really non-dangerous kind of vampire I guess, that mostly feeds off the marrow of stuffed crust pizza. *sigh* I sure miss the undead board.

Hoho. The discusion here is really "general".

Anyway, I have found a software call "Fun CD", it has a safeCD function which do exactly what I want. However, the technology is so new that the software only support RICOH CDRW (it was actually developed by RICOH). I don't understand why such a simple function would be still near-non-exist up to now when CDRW has developed for few years already.

Do any of you know any (professional) website that talk about any aspect of burning CD?

Thanks.

In other words, no. But how secure do you need this? Couldn't you just add the hidden attribute to everything but the "decrypter" prog? Otherwise, you could at least put everything on the CD into one big encrypted file so you don't have to handle all the file allocation table functions (this at least gives you a known spot where the file information begins). Then the decryption program would act as explorer to the "hidden" info once the password was verified.
