They do exist, only in Plan 9 from User Space.

They don't exist in Plan 9 only because we don't have
anything that actually uses dsa keys.

As Russ said:

[9fans] dsa keys.

[quanstro]

is there a reason that auth/dsagen (and friends) do not exist
(other than nobody wanted to write them)?

ssh doesn't support dsa not because there is no dsagen
but because it only supports version 1 of the protocol.
if you write an rsa-only ssh2, i will be happy to add the
dsa code.

Not really: you need SSH2 for DSA to be useful.

[quanstro]

these days many places require dsa ssh keys.

Re: [9fans] dsa keys.

[quanstro]

true enough. but this can become chicken-and-egg logic.
as in: ssh doesn't support dsa because auth doesn't support dsa.

i thought that getting auth to support dsa keys would be a good start
on ssh support.

Re: [9fans] dsa keys.

[quanstro]

i know. i was just objecting to the logic of "we cant build x because
we also do not have y."

hopefully i'll have time. i still have this unsightly ide drive
sticking out of my plan9 machine. ;-)
