This module lets users use their own SSL certificate to connect to a server, such as CertFP.

You will have to generate an SSL certificate to use with this module. Either place it at `~/.znc/users/<user>/networks/<network>/moddata/cert/user.pem`, or use the web interface to upload the certificate.

You can usually test if Cert is supported by services simply by sending /msg NickServ cert. If you get an error about “Insufficient parameters for CERT,” CertFP is supported. If you get an error about unknown command, or no response at all, it may not supported. While this is a fairly reliable test, it may vary by IRC network, for example Rizon supports Cert but uses the command /msg NickServ access instead.

Arguments

This user/network module takes no arguments.

Generating a certificate

You can use the following openssl commands to generate a certificate

This command would produce a 2048-bit certificate which would expire in 3650 days. You can modify the arguments to openssl to change this. user.pem is the certificate you will need to add to ZNC.

openssl req -nodes -newkey rsa:2048 -keyout user.pem -x509 -days 3650 -out user.pem -subj "/CN=YourNickname"


Enter this to get the fingerprint:

openssl x509 -sha1 -noout -fingerprint -in user.pem | sed -e 's/^.*=//;s/://g;y/ABCDEF/abcdef/'

If you are following instructions from certauth, you can stop here. Your certificate is user.pem, and you must tell your client to use it.

Add the fingerprint to your NickServ account:

/msg NickServ cert add fingerprint

Now move the cert your folder:

mv user.pem ~/.znc/users/<user>/networks/<network>/moddata/cert/
