Channel founder may set this mode so that

founder rights using CUMODE or JOIN commands.
If the <pubkeyfile> and <privkeyfile> is
server. If these are omitted then the default
SILC keypair is used. Normally you do not need
to provide these arguments.
- C [{[+|-]<pubkeyfile> }] (*)

Set/unset channel public key mode, and add/remove
channel publics key from the channel public key
list. When this mode is set only those users
require any arguments. If mode requires an argument then only
one mode can be set at once.

+
+ /CMODE * +f
+
+ Reclaim founder rights (and operator privileges) for you channel:
+
+ /CUMODE * +of mynick
+
+ You can do the same during joining:
+
+ /JOIN yourchannel -founder
+
+ Change channel founder keypair on your channel. You can do this if
+ you want to transfer founder rights to some other user or if you
+ created new keypair. The operation requires that you have a copy of
+ the old keypair:
+
+ /CUMODE * +f mynick /path/to/old/pubkey /path/to/old/privkey
+ /CMODE * +f /path/to/new/pubkey /path/to/new/privkey
+
+ or simply /CMODE * +f if you are already using the new keypair.
+
+ Here's how to transfer founder rights to different user using
+ temporary keypair:
+
+ Create temporary keypair:
+
+ # silc -C
+
+ Become founder on your channel:
+
+ /CUMODE * +f mynick
+
+ Set the temporary keypair on the channel and then send the key
+ pair to your friend with for example encrypted Email:
+
+ /CMODE * +f /path/to/temp/pubkey /path/to/temp/privkey
+
+ Tell your friend to give the following command to become founder:
+
+ /CUMODE * +f yourfriend /path/to/temp/pubkey /path/to/temp/privkey
+
+ Your friend then sets his own keypair on the channel:
+
+ /CMODE * +f
+
+ After this the temporary keypair can be removed and your friend has
+ become the founder of the channel. This way the founder rights can
+ be transferred without ever revealing your own keypair. When your
+ friend becomes the founder your founder rights will be removed by
+ the server automatically. It is also possible to continue using the
+ temporary keypair, thus sharing founder rights with two or more users.
+ Note that it is possible for only one user at a time to have founder
+ mode on the channel even if they share the keypair.
