Channel founder may set this mode to be able to regain
channel founder rights even if the client leaves the
channel. The <auth payload> is the Authentication Payload
- consisting of the authentication method and authentication
- data to be used in the authentication. The server MUST
- NOT accept NONE authentication method. Also, if the
- method is public key authentication the server MUST NOT
- save the authentication data from the payload as the
- data is different on all authentications. In this case the
- server only saves the authentication method. However,
- server MUST verify the sent authentication payload and
- set the mode only if the verification was successful.
-
- Note that this mode is effective only in the current server.
- The client MUST connect to the same server later to be able
- to regain the channel founder rights. The server MUST save
- the public key of the channel founder and use that to identify
- the client which is claiming the channel founder rights.
- The rights may be claimed by the SILC_CUMODE_FOUNDER
- channel user mode using SILC_COMMAND_CUMODE command. The
- set authentication data remains valid as long as the channel
- exists or until the founder unsets this mode.
+ consisting of the public key authentication method and the
+ authentication data for that method. The passphrase
+ method cannot be used with this mode. The server MUST NOT

+ The public key of the founder is sent in the

+ This way the founder can reclaim the founder rights back

Typical implementation would use [+|-]f on user interface
to set/unset this mode.
