{- Security:
-
- The transfer info file contains the user-supplied key, but
- the built-in guards prevent slashes in it from showing up in the filename.
- It also contains the UUID of the remote. But slashes are also filtered
- out of that when generating the filename.
-
- Checks that the key being transferred is inAnnex, to prevent
- malicious spamming of bogus keys. Does not check that a transfer
- of the key is actually in progress, because this could be started
- concurrently with sendkey, and win the race.
