I am looking for a cross platform (OS X 10.10 + Windows 7) encryption solution which can fully encrypt, decrypt and modify a USB disk (full disk encryption). Truecrypt does this, but you need admin privileges to run it.
Can anyone recommend an alternative (i.e. a portable application) which runs with only standard user privileges under Windows 7? I have full access to the OS X machine. Preferably open source, but I am open to suggestions.
