Decrypting a .c11 file or .c11.zip file bundle

ℹ️ These instructions assume you have installed the Confidencial desktop app. You can also decrypt a .c11 file using the web app.

ℹ️ These instructions show you how to decrypt a Confidencial-protected file. Individual files that are protected with Confidencial’s desktop or web app (and are not natively-supported) typically ends with a “.c11” file extension, while a file bundle (that contains multiple Confidencial-protected files) typically ends with a “.c11.zip” extension.

Start by double-clicking the .c11 file; this will open the Confidencial desktop app

1. Drag and drop the Confidencial protected file into the encryption box or click choose files and select the file in the Encryption Tools page

   
2. Click Decrypt

   
3. If the protected (encrypted) file is a .c11 file, you can save an unprotected (decrypted) version of the file by clicking Save File. If the protected file is a .c11.zip file (a file bundle), clicking Save File will allow you to save a zip file containing unprotected versions of each file within the bundle.

   

✅ The completes decryption of Confidencial-protected files. These unprotected files are now available to be opened in their native viewers/editors.

⚠️ Following use (viewing and/or editing), it is strongly recommended to re-encrypt the unprotected file(s) and permanently remove (delete + empty trash) the unprotected versions from your disk
