What would be the best way to encrypt a file in Ubuntu 12.04 but in a way that could be read by a Windows 8 user?

Would creating a Truecrypt volume work if I just sent the truecrypt file over?

Any other methods?

    freeotfe.org Works for luks volumes. And you can have files that mount with losetup on the linux side and freeotfe on the Windows side. – RobotHumans Mar 18 '13 at 6:20

    what is the point first to encrypt stuff, which later is readable in windows 8? any -seldomly- occuring windows malware hence can read all your data, right? sure you keep win8 clean ;) No offence intented, but I would really like to know what could be the reasoning behind this. I am quite glad that my Win cannot read my linux partitions – humanityANDpeace Mar 18 '13 at 6:56
  • @hbdgaf FreeOTFE was discontinued in 2013, and a fork sprung up: DoxBox. It's still "Compatible with Linux encryption, Cryptoloop "losetup", dm-crypt, and LUKS. " – landroni Jan 25 '15 at 18:07

Yes, you are good to go with TrueCrypt.

In case you want to encrypt the whole system drive you must refer this guide http://jan-krueger.net/development/truecrypt-system-drive-on-linux
