Legacy MACs and Ciphers: Why?
..., and legacy Ciphers (anything in
cbc-mode, arcfour*(?)) enabled by default?
My proposal would be to change the defaults for ssh_config and
sshd_config to contain:
MACs hmac-sha2-256,hmac-sha2-512,hmac-sha1
Ciphers aes128-ctr,aes192-ctr,aes256-ctr
...removing md5, truncated versions of sha1, umac64 (for
which I can find barely any review), any cipher in cbc mode
and other non-mainstream algorithms.
Additionally, why does ssh_config prefer hmac-md5 over less
broken algorithms?
Even if the above reduction of attack surface were not to happen,
ssh_config could be changed such that the client p...

OpenSSH performance with VIA padlock
Hello list,
please spend a minute considering these facts and maybe there is something to
improve:
1) VIA Eden based board can write AES256 encrypted information on HDD at >
60MB/s
2) iperf shows NIC speed 69MB/s
3) openssl tests have even better results
4) openssh can transfer AES256 encrypted information at < 27MB/s (and worse
with HDD encryption)
It is better with openssh 5.x, than
