makes an interesting suggestion:
{{{
It would also be nice, if we lengthen the service addresses to accomodate
more security, to allow hyphens or some other divider character in the
name
that will be ignored. This would allow names to be more memorable, even in
their current form. These characters should probably be stripped off in
the
TBB from any Host: headers, at least, to resist using them as a client
fingerprinting side-channel. There is precendent for this sort of thing:
gmail ignores periods (.) in the "username" portion of its email
addresses.
}}}
I bet there are complications that we haven't thought of -- the different
versions of the Host: header is an interesting fingerprint, and similarly
I would worry about different versions of the same name being handled
differently by some caches, Tor's mapaddress to virtual addresses, etc.
Also, if we indeed make hidden service names much longer, then the Shallot
approaches will be much less effective at making them mostly memorable.
But I figured we should have an actual ticket where we make some
decisions, rather than letting it get lost as an old blog comment.
