In article <5609c6f296a54b24a2b7a5cd319fbd46@cert.org> you write:

I do all of my scripted downloads with wget or curl which I think is
pretty typical. In those two programs, changing from ftp to https generally
only involves changing ftp:// to https:// in the command arguments.

I'd also be interested in hearing about what other FTP clients people are using
that are hard to switch to https.
