c# - Best way to make application available for distribution -

-

i've developed software application , have reached point need find easier way supply updates users. i've created "installer" application - simple c# application connects ftp server, supplies credentials, brings down parts of application , assembles it. installer called main application if user chooses update version of application. (the first step of installer kill main application process, thereby allowing files overwritten.) determine if new version available, application reads simple text file hosted on website (i.e. www.mydomain.com/versionfile.txt) . text file contains latest version number, main application uses compare version.

it works, can cumbersome if user on site not allow ftp access (which often.)

so not subjective, here specific question: there secure way make application files available on website download?
secure, mean c# installer application needs supply correct credentials before being able download application files users pc.

i've seen how 1 developer distributes application via dropbox public folder, open everyone, i'm trying avoid.

thanks in advance.

http (or better https if care unauthorized third parties sniffing passwords) do, block less often, , can fetch file ftp (or easier). have password protection ftp, called basic auth
