If you haven't set up the requisite SASL authentication, we recommend SASL
EXTERNAL. You'll need to generate a client certificate:
- openssl req -x509 -sha256 -new -newkey rsa:4096 -nodes -out freenode.pem -keyout freenode.pem
+ openssl req -x509 -sha256 -new -newkey rsa:4096 -days 1000 -nodes -out freenode.pem -keyout freenode.pem
and consult your IRC client's documentation to find out how to use it to
connect. Connect to freenode over TLS on the plain Internet and `/msg NickServ
