So a bunch of us were sitting around talking one night and decided just for the lulz we would also start using FiSH Encryption in one of our back back channels on IRC. Not everyone that is in the channel are neck-beards and use irssi; some even don’t use XChat. To easy the transition for everyone, we setup a ZNC server to be a bouncer that also handles the FiSH encryption (yes this can defeat the purpose of FiSH, that’s why everyone is required to use SSL when connecting.)
As we were setting up, those of us who already were using FiSH couldn’t tell who was talking encrypted and who wasn’t. So @noah256 brought up the idea of prefixing encrypted messages. Later he also realized this can be spoofed; so he suggested to also prefix unencrypted messages from expected encrypted targets. At the same time, we realized when trying to talk to people without FiSH installed, it wasn’t really easy to temporarily send unencrypted messages so we also added a prefix to tell the module to not encrypt the message.
My modified module can be found in my znc-fish repo on GitHub
