Cipher: a command-line tool to decrypt/encrypt files and directories (een recursively) on Windows

Posted by jpluimers on 2020/07/03

A while ago, I had to mass encrypt a lot of directories and files on Windows for some directories in an existing directory structure.

This helped me to find out which ones were already done (it lists all encrypted files on all drives; the /n ensures the files or encryption keys are not altered):

cipher.exe /u /n /h

This encrypted recursively in one directory B:\Directory:

cipher /D /S:B:\Directory /A

It also has options to wipe data (/W), export keys into transferrable files (/X) and many more.

If you like the Windows Explorer more then to encrypt/decrypt (it is a tedious process): [WayBack] How do I encrypt/decrypt a file? | IT Pro.
