...A simple solution would be to add support for an ssh_config(5) option to limit the number of attempts, such as HostbasedMaxTries or MaxHostbasedAuthTries. A more flexible (although more complicated to implement) solution would be to provide a means of specifying the keys or key types to try; e.g. HostbasedKeyTypes ecdsa,ssh-rsa. -- You are receiving this mail because: You are watching the assignee of the bug.

I am trying to understand the details of the deprecation notice. Because I am getting people asking me questions. And I don't know the answer. Therefore I am pushing the boulder uphill and asking here. :-) Damien Miller wrote: > Future deprecation notice > ========================= > > It is now possible[1] to perform chosen-prefix attacks against the > SHA-1 algorithm for
