"Your file is first securely encrypted using a secret key (AES-128) with Javascript on your device.
Once it has been encrypted, the encrypted data is uploaded to a NoFile storage server over a secure HTTPS connection preventing any malicious users from seeing what you're uploading (as an extra layer of security).
Only those with the secret key (which is in the URL) will be able to see the correct content and filename - if a single character of the key varies, then the file will be unrecognizable."
You need to set this as your preferred method on the upload page.
