We need to setup an FTPS server using IIS to allow a client to pull files down from us. Our data center requires that all files be encrypted on disk and decrypted on the fly by our server before returning the file to the client. We've done similar things in the past for HTTPS by creating an HTTP Handler and doing the decryption in a custom module, but we can't figure out a way to do the same for FTPS. We know that other FTPS servers can do this sort of thing, but our operations group requires us to use IIS. Does anybody know if there's a way to do this (or the functional equivalent) using FTPS on IIS?
Thanks in advance.
