I have some external hard disks. I have encrypted them with the default encryption utility that comes with OS X, so I get encrypted HFS+ disks. Now I need to encrypt the same disks, but I need to be able to read them in OS X, Linux (Ubuntu distro) and Windows.
What software I could use for encrypting those external hard disks with a password? So when I go to another PC, I just have to install the software, introduce the disk, then the password and see my files.
