access security via www & indexer

Dear All
I understand that ftp access is inherently insecure due to the ftp protocol, ie if I have a password protected ibay and enable ftp access, (ftp://ibayname@ftp.mydomain) then it is possible for the password to be captured by anauthorised means.

If I use the lophty indexer program or Shad Lords dirindexer, and enable my ibays for password protected access, and then access these via www.mydomain/ibayname and password, does this give me secure access to files in that ibay, ie is my password safe from unauthorised eyes, robots, hackers etc.

Thanks & Regards
