From: Demec on 29 Apr 2010 17:58 So far the tutorials I've seen are for encrypting text and then decrypting it back. So for example you have a plaintext = "some text" you encrypt it and the you decrypt it depending on how you encrypted it. What I am looking for is to encrypt a whole file and then store it. for example I allow my users to upload .doc/.xls files in a Rails app. I want to encrypt those files so I would not store them like that, and in case a user wants to download it back the app will decrypt it and then send it to user. How can I do this ?
