Software recommendation for Windows-Linux encryption
 

Hello:

I have Windows 8.1 and Slackware Linux 14.1 installed in a laptop, and I have files which I'd like to keep encrypted with both OSes.

I've encrypted the partition where Slackware Linux was installed, but my files in the Windows 8.1 partitions are saved unencrypted, and I fear what could happen if anyone would steal my laptop.

I've made some searches in the internet for disk encryption software; they took me to BitLocker (Windows, propietary) and FreeOFTE (unmantained).

I wondered if there is some GNU libre software which I could use to encrypt my files in Windows 8.1, and then decrypt and use them under Slackware Linux, also (like FireFox, but for encryption...).

Could you recommendme something?.

Thanks in advance.

A cross-platform suite such as GPG ought to be able to do the job nicely, and you should be able to easily verify that the files are transportable as expected.

Naturally, you'll need to be aware of some issues with regards to the decrypted content, such as the differing "end-of-line" conventions (CR/LF vs. CR vs. LF) between the two system-types, but these by themselves have nothing in particular to do with the encryption.

You want the strong encryption capabilities and, especially(!), key-management capabilities, of these well-established, peer-reviewed, industry standard systems. (You emphatically do not want to try to "roll your own" crypto.) It will also be important that you use them in the "right" way, so be very attentive to the "best practices" documentation.

"On-the-fly" encryption
 

I should have specified better (sorry, english is not my native language):

I'm meaning encrypting files as they are saved in the disk, it would be like a "Private" folder in my Windows "/home" which would be de-encryptable later in Linux.

I admit I don't know enough of GPG to assert that this is possible (or not) under Windows, thought.

Is it possible or should I look for another software option?

Truecrypt is excellent, cross-platform, and free.

I would also say that truecrypt would be the best option in this case.

AFAIK, TrueCrypt does not support Windows 8, or 8.1.

Additional question, are there any Linux untilities that would Linux access to a Windows Bitlocker partition?

It's source is available (although not truly FLOSS) you could try to compile it...

There was a utility for linux called DiskLocker (i cant find it now) that worked a while back. But probably not on Windows 8.

Get Windows 7?

NEVER trust closed-source encryption.

I'm not saying that they succeeded in backdooring it, but if they did, you wouldn't know.
