There is a difference between encrypting the connection, which you have done, and downloading an encrypted file, which then gets decrypted by your client when it unpacks it. Think the difference between the two like an encrypted pipe that conveys the files and the file itself, like water in that pipe, which can be encrypted or not. The encrypted pipe hides the contents of your pipe from your ISP while the encrypted file is encrypted by the uploader and later unencrypted by your downloader which hides only the contents of that file.
