[Ach] SSH Pubkey authentication?

[Lorenz Intichar]

Dear List,

would you think it worth while to recommend (and/or explain) SSH pubkey
authentication in ACH, or would that be considered Off-Topic in a crypto
manual?

I´d like to propose SSH PubKey procedures (i.e Key Generation, open SSH
"PasswordAuthentication no" and PubKey Auth in IOS / ASA) as a general
security enhancement, but would like to get some opinions about this topic
(or off-topic ;-) ) first.

Kind regards,
Lorenz
