+
+The Debian package for Tor has moved away the onion keys upon package
+upgrade, and it will have moved away your identity key if it was created
+in the affected timeframe. There is no sure way to automatically tell
+if your key was created with an affected openssl library, so this move
+is done unconditionally.
+
+If you have restarted Tor since this change (and the package probably
+did that for you already unless you configured your system differently)
+then the Tor daemon already created new keys for itself and in all
+likelyhood is already working just fine with new keys.
+
+If you are absolutely certain that your identity key was created with
+a non-affected version of openssl and for some reason you have to retain
+the old identity, then you can move back the copy of secret_id_key to
+/var/lib/tor/keys. Do not move back the onion keys, they were created
+only recently since they are temporary keys with a lifetime of only a few
+days anyway.
+
+Sincerely,
