CertFP Log-in

CertFP, short for Certificate Finger Print, is another method to log you in to NickServ. Instead of a password, it uses a Client Certificate.

In order to use it, you

  • first need a certificate,

  • then configure Irssi to use this certificate,

  • and finally register the certificate with NickServ.

Irssi does not have built-in certificate management commands, so you need to use an external tool like openssl to create the certificate.

It is necessary that the certificate be available as a file; PKCS#11 is not supported.
