I know that in linux and osx it's easy to create a disk image that is encrypted and (given you know the key) can be mounted and you can read/write its content.

Under windows there are plenty of tools to encrypt single files, I also know how to create encrypted read-only iso but I need a way to create an image (let's say 10GB iso file) that once mounted behaves like a normal folder and applications can read/write in it without knowing that it's encrypted. Encryption must be transparent to the applications.

PS: I've mentioned "iso" but it's not really important what format the disk image will be.

    I would just use a TrueCrypt container is the best method.

  • @Ramhound Sadly TrueCrypt project has been discontinued, on their page it says "WARNING: Using TrueCrypt is not secure as it may contain unfixed security issues. This page exists only to help migrate existing data encrypted by TrueCrypt."

True crypt container is one of best method,otherwise I think use BestCrypt Container Encryption is also good. if encrypted file containers with TrueCrypt, you can replaced by BestCrypt Container Encryption.

I ended up using ProxyCrypt http://reboot.pro/topic/19128-proxycrypt/ which is free and does exactly what I need. It's not really "famous", and I won't probably trust it for a production environment but it's an active project and for a paranoid private user is fine.
