previously thought.

The authentication protocol used in rsync is a 128 bit MD4 based
challenge response system. Although I believe that no one has ever
demonstrated a brute-force break of this sort of system you should
realize that this is not a "military strength" authentication system.
It should be good enough for most purposes but if you want really top
quality security then I recommend that you run rsync over ssh.
challenge response system. This is fairly weak protection, though (with
at least one brute-force hash-finding algorithm publicly available), so
if you want really top-quality security, then I recommend that you run
rsync over ssh. (Yes, a future version of rsync will switch over to a
stronger hashing method.)
Also note that the rsync daemon protocol does not currently provide any
encryption of the data that is transferred over the connection. Only
