I believe this is a more specific question than Alternatives to TrueCrypt? with different answers.
I have USB flash drives which I carry around and use on various computers at work and at home. I would also like to be able to use this on computers belonging to friends and on public computers where I don't have administrator rights and/or cannot install software.
Operating systems I would like to be able to use would include:
- Windows 7 starter edition 32-bit
- Windows 7 home premium 64-bit
- Windows Vista 32-bit
And other popular variants of Windows (perhaps even some old Windows XP variations)
The content might include photos or other personal data that I would like to be protected in case I lose the USB flash drive (e.g. by dropping it, not by leaving it in a computer - I suspect the latter is too difficult to defend against).
I have tried U3 and TrueCrypt. I believe U3 encryption is easily circumvented and there are clearly some concerns currently about TrueCrypt. I worry that FreeOTFE appears to have been abandoned by its authors and its website taken over by spammers. Bitlocker-To-Go seems to be read-only or unavailable for the operating systems I am interested in.
