We would like to encourage you to authenticate via SASL, so you will already be authenticated before your client tries to join channels, which results in a smoother connection setup.

Certificate Fingerprint (SASL External, CertFP)

To enroll the fingerprint of the certificate you are currently connected with call:

/msg NickServ cert add

Presenting the client certificate on connect will subsequently authenticate you against services.

We're currently using SHA256 fingerprints for SASL External and CertFP.


If you are planning to use ECDSA-NIST256P, generate prime256v1 ecparams and store the public key within the services. During the connection phase a challenge-based authentication will happen.

Generate the ecparams and retrieve the public key

$ openssl ecparam -genkey -name prime256v1 -out ecdsa.pem
$ openssl ec -noout -text -conv_form compressed -in ecdsa.pem | grep '^pub:' -A 3 | tail -n 3 | tr -d ' \n:' | xxd -r -p | base64

Configure the public key in your account

/msg NickServ set property pubkey <pubkey>

Configure ecdsa-nistp256-challenge in your client

/set irc.server.hackint.sasl_username <account>
/set irc.server.hackint.sasl_key </path/to/ecdsa.pem>
/set irc.server.hackint.sasl_method ecdsa-nistp256-challenge


Other ways to connect exist, they use transports, check the menu for that.
