[tor-talk] RSA identity keys

[grarpamp]

Tor routers and hidden services use these.

Various other tools can utilize them for sign
and encrypt. A number of useful scenarious
can be envisioned.

But I can't put a passphrase on them
because I've no way to start Tor if
they have a passphrase set.

Also, without a passphrase, they are more
prone to undesired use if copies are obtained.

Can some future version of Tor be made to
deal with that using the usual sources
of passphrase... stdin, pathname, descriptor,
environment? Ala: apache and certs, ssh-agent, etc.
