Cross-Platform Encryption?

Posted by Cliff on from the lowered-barriers-for-information-protection dept.

Dr. Sp0ng asks: "I'm sure a lot of Slashdot readers carry around USB keychain drives or other portable media. What cross-platform encryption solutions have you found for these? The ideal solution would be something which can create a true encrypted disk image in a file, along with Windows and OS X (and perhaps even Linux) standalone executables which can mount these without requiring you to install anything. Obviously something like GnuPG could be used, but it won't let you create an actual mountable filesystem. There are plenty of Windows solutions, and Mac OS X users can simply create an encrypted DMG, but are there any cross-platform solutions out there?"

  1. A simple solution by waynegoode · · Score: 4, Interesting

    This is not exactly what you are looking for, but how about ...

    A big ZIP file on the drive.

    + It is encrypted.
    + It is cross platform if the underlying File System is.
    - The computer needs a ZIP file decrypter and a encrypter if you want read/write.
    - It acts like a file system, but really isn't.
    - Not the best encryption.

  2. QEMU? by kisielk · · Score: 4, Interesting

    I've been thinking about doing a QEMU setup on a flash drive with an encrypted file system, and including QEMU executables for various OSs. You coul d then boot up the QEMU image, which could have networking support with Samba or something, and then access the files over the network.

    I haven't actually tried this yet, and I'm not entirely convinced it's a good idea, but it's one suggestion. Has anyone else tried this? Any comments or suggestions?
