I think this is going to end up in an discussion if it would be save or not,
but I think it is. If someone is "sniffing" and get's the HTTP request
instead of the HTTP server, he or she doesn't get the password, but it's
encrypted (or with MD5, that depends on the HTTP request). Ofcourse, it
isn't secure, he or she could trie an dictionary or brute-force attack, but
is is more secure, and I think that's a good thing.

What do you feel about the idea to create a attribute which allows the
client to send an (MD5) checksum of the file, to determine if the transport
went well?

Another idea, maybe make something like a "checksum" value in the type
attribute in the  <INPUT> tag, which takes a checksum of all data?
