Is there a way to protect, encrypt, or password the CD's I burn?

Is there a way to protect, encrypt, or password the CD's I burn?



I have seen some encryption programs like "CD Protector", but have no clue how they work.


Is there a way I can use an imaging program like PowerQuest Drive Image, to create an image of a select folder filled with files and then password protect it?

With these kinds of "images" is there a way I can view what files are in the image and extract them individually with a password?


Thanks all!

Thanks for the input!

I had inititlaly thought of that, but can you double click on a zip and see what files on it (after providing a password of course) and extract them one at a time?


It would be much easier to extract each individual file, rather then unzipping the whole thing every time.

I am expermineting with this using PowerQuest Drive Image

It seems to work ok so far


Any other ideas?

Cheers!

Sure you can extract individual files from a password protected zip. Keep in mind, however, that you need to provide the password to extract the files, not to view the contents of the zip.

zip file passwords can be broken, just need time

http://www.dvdtalk.com/forum/showthr...&highlight=zip

I go into some times in that thread

Ok, problem

I am using PowerQuest Drive Image 5.0

and Win98 (althought will have a dual boot soon with XP, but off the subject I suppose)


I could have SWORN that there was an option to make an image of just a set oif files or folders, WITHOUT having to do the entire drive!

Anyone have any info on this?

I would like to go with this PowerQeust Drive Image option of password protecting my files, b/c you need the password to VIEW and EXTRACT ANY files from the image.


Any ideas?

Can I do the "zip" thin you described with the standard free WinZip software? Or do I need to get the pay version?

Subject: [3-19] How can I compress or encrypt data on a CD-ROM?
(2001/08/01)
The easiest way is to use your favorite compression or encryption utility and process the files before putting them on the CD. However, this isn't transparent to the end user.

CRI-X3 enables programs like DoubleSpace to work on a CD. It's intended for a publisher or for significant internal use, and the licensing is priced accordingly. See http://www.cdrominc.com/. (Side note: the company filed patent infringement suits against Traxdata and CeQuadrat in Sep 1998 for distributing CD compression software. This might account for the dearth of similar applications.)

A straightforward solution is to write all of the files onto the disc as .ZIP files, and then use ZipMagic (formerly ZipFolders) to view the contents. It can be found at http://www.ontrack.com/zipmagic/.

PGP at http://www.nai.com/ (was http://www.pgp.com) has some good encryption software, but none of it seems directly applicable to software distribution. PGPdisk, available for the Mac, might be useful but it isn't clear whether it can be used to distribute CD-ROMs.

ScramDisk, from http://www.scramdisk.clara.net/, writes files into encrypted "containers" on disk. It can be used with CD-ROMs, runs under Win95 and Win98, is free, and even includes source code.

http://www.c-dilla.com/ had information on CD-Secure 2, which allowed publishers to distribute network-licensed or "pay for the parts you need" products, and CD-Compress 2, which provides a way to compress data transparently on production CDs. The company is now part of Macrovision.

EnCrypt-CD encrypts the blocks as they are written to CD. It's a shareware product, available from http://www.shareit.com/programs/102046.htm.

Encrypted Magic Folders from http://www.pc-magic.com/ claims to transparently encrypt data as it's being used. Whether it would work from a CD-ROM isn't stated.

You can install a cryptographic filesystem (called "CFS") under Linux; see http://www.linuxdoc.org/HOWTO/Securi...6.html#ss6.10. Create a crypto-fs, copy your data onto it, then use mkisofs with Rock Ridge extensions enabled to create an ISO-9660 disc image of the encrypted data. Burn the image to CD-ROM.

You may be able to use E4M, from http://www.e4m.net.

BestCrypt, from http://www.jetico.com/, lets you create encrypted virtual volumes in a file that can be stored on CD-R media.

You can get PC Guardian's CD-ROM encryption from http://www.pcguardian.com/.

WinDefender, available from http://www.RTSecurity.com/products/windefender, provides transparent CD-ROM encryption from Windows.

I can not find the password option ANYWHERE!


Also-

DO you guys remember back in the day you could pick the LEVEL of compression you wanted for a zip file? Low, medium and High?

I would settle for a password option though

Anyone?



Oh, and just to clear it up. Are you saying you CAN view all the file names inside a zip that is password protected but you need a PASSWORD to view them (open them?)

Cheers!

You can specify a password when you create a new archive and add files to it. Or, you can select a bunch of files, right-click and 'Add to ZIP', and click the 'Password' button on the resulting dialog.

You can still select the compression level when you add files to a new archive. It's on the same dialog as mentioned above. I always set mine to 'maximum'.

Yes, you can still see the filenames inside the archive, but you can't extract them without the password.

I've played around with ScramDisk, and it looks like it would be very effective. Bestcrypt mentioned in RoQuEr's post sounds similar but I've never used it.

Great-

finally got the passwords and compression level options to show themselves in WinZip

I had to go itno WinZip classic (Not the wizard)


but, no matter what level I chose, while zipping the 700MB AVI, file it only compresses down to about 692 MB.

(wow, 8MB space saved!) :-)


What is up with that??


I think I will check out scramdisk next

Cheers!

Some file types don't compress as well as others. I'm guessing the avi you are trying to zip is divx or something like that? If so, the avi is already compressed about as much as it can be. There isn't much redundancy left in those avis. You probably have to re-encode it at a lower bitrate to get it much smaller.
