[Question brought here from the security section]
Is there any easy way I can decrypt a folder that has been encrypted with Windows 7? I am using Ubuntu 11.10 to decrypt the folder.
EFS - Encrypting File System - is native to Windows & Microsoft. Microsoft have not released this as opensource - and no-one (as yet) has clean reversed engineered this.
I'm afraid - the only way you will be to decrypt a windows 7 file and folder encrypted using native windows encryption is via windows itself.
Depends on what you encrypted the file with. LUKS, truecrypt, and gpg are all cross platform.
Windows - freeotfe
Ubuntu - To set up an encrypted partition in Ubuntu, using /dev/sda4 as an example,
Add a line for your crypt
Again, add a line for your crypt in
Make a mount point
Now you can mount it with
GPG will run on both windows and Ubuntu
For windows try gpg4win
