In our previous article, we’ve seen how to encrypt files/folders using Encrypting File System (EFS) feature:
Now in this article, we’ll see how to decrypt previously encrypted files/folders. There are some conditions which must be fulfilled to decrypt the content. Firstly, the account should have privileges to decrypt and should have decryption key. In the absence of correct decryption key, you won’t be able to decrypt the file/folder.
We’ve provided two methods here and you can use either of them to decrypt the content.
