Signs data using the specified channel signing key.
Usage:
channel_sign [<channel_name> | --channel_name=<channel_name>]

channel_sign [<channel_name> | --channel_name=<channel_name>] [<channel_id> | --channel_id=<channel_id>]
[<hexdata> | --hexdata=<hexdata>] [<salt> | --salt=<salt>]
[--channel_account_id=<channel_account_id>...] [--wallet_id=<wallet_id>]
Options:
--channel_name=<channel_name> : (str) name of channel used to sign (or use channel id)
--channel_id=<channel_id> : (str) claim id of channel used to sign (or use channel name)
--hexdata=<hexdata> : (str) data to sign, encoded as hexadecimal
--salt=<salt> : (str) salt to use for signing, default is to use timestamp
--channel_account_id=<channel_account_id>: (str) one or more account ids for accounts to look in
for channel certificates, defaults to all accounts.
--wallet_id=<wallet_id> : (str) restrict operation to specific wallet
