I am wondering if it is possible to encrypt a CD-R or CD-RW (DVD equivalent) so I can save sensitive information, frequently. I don't want to use a .RAR archive, for example, as I would have to re-write the entire archive, which I can't do on a CD or DVD-R. Is this even possible, using encryption software? Please help!

EDIT: If you have any software suggestions, any freeware/open source?

Diky moc, skusim to. Jste z Slovenska?

Thanks, I'll have a look at Secret Record v. 3. Any other suggestions? Is encrypting a CD/DVD possible?

Not really sure I fully understood what you need, can you explain better what type of data you need to protect, how big are the files and how often you need to copy the files to CD?

The "standard" freeware/Open Source is Truecrypt:
http://www.truecrypt.org/

But maybe you need something different/simpler, here are a few crypting programs:

Sure! Word doc files, mostly, that contain sensitive information (names, for example). I want to encrypt these in a folder on my hard drive, which seems straight forward, but I'd also like to back them up periodically (twice a month, for example) to an optical disc, but have the disc be encrypted.

Just Google "data encryption program" and you'll find *many*... some are more secure than others, choose what you need.

Then, easiest solution is following LLXX advice, or use one of the programs in the 2nd link I posted.

A very nice "self-standing" and portable solution is here:

Another option you might want to explore is the use of Steganography:

here is an example program:

FOR ALL. I’m terribly sorry.

[Egon's Dragon]

Hmmm, too many **** programs. I'll have to search a bit. But is it possible to do what I want? Encrypt a CD-R/RW and back up to it frequently?

No, this is a English-only forum

Well anyway, Googling is like finding a needle in a haystack. I'm looking for something freeware, that specifically encrypts optical media. Is there anything good on sourceforge?

[phkninja]

There is no freeware app to do what you would like (as in create an encrypted Disk) directly, you could encrypt the information and use an iso creator program. Then you could click the iso file and burn (instead of manually clicking the files from within a buring program, if you make a cd image it might be easier).

For example, write a batch file with a commandline encrytor program that encrypts the contents of the folder and also creates an iso from the folder

eg
blowfish -e backup\*.*
cdimage.exe -lBackup -x -h -o -oc -m -j1 .\backup .\backup.iso

then runthe batch file every time you want to back up data

What about TrueCrypt?

[phkninja]

Truecrypt makes an encrypted virtual filesystem.

Quote

Creates a virtual encrypted disk within a file and mounts it as a real disk.

Basically it creates something like an encrypted folder that contains all the encrypted data. But it requires truecrypt to mount he file as a drive. This could work on a cd-rw or dvd-rw (dont know, i never tried).
