This page describes how to connect, and identify yourself to services securely via a certificate fingerprint.
A major advantage of using a CertFP to authenticate is that you don't have to use
/msg NickServ IDENTIFY anymore.
By using SSL you are also encrypting the connection between you and the server.
Creating the certificate
We will be using OpenSSL to create the certificate. If you haven't already, please install OpenSSL using these instructions:
|Go here: http://www.slproweb.com/products/Win32OpenSSL.html. During the time this tutourial was written, windows 7 and "Visual C++ 2008 Redistributables", along with "Win32 OpenSSL v0.9.8l Light", were used. Please note that you should select "The Windows system directory" when it asks you where to copy the dll files to, or it may not work.||Most distributions come with OpenSSL or have the OpenSSL package in their repositories. If they don't, please go to http://www.openssl.org/ and install it.|
Generating a .pem
To generate the required .pem file, you will need to create a key and a certificate first:
Assuming your commands were entered successfully, you will be asked some questions. Fill them in similarly to what is shown below:
Country Name (2 letter code) [US]:US State or Province Name (full name) [Texas]:Michigan Locality Name (eg, city) [San Antonio]:Grand Rapids Organization Name (eg, company) [Stealth3]: Rizon Organizational Unit Name (eg, section) [ISP]: IRC Common Name (eg, YOUR name) :Rebel_n00b Email Address :firstname.lastname@example.org
This will create two files, which you will need to combine together:
Configuring your client
This section varies highly from client to client.
Move the Rizon.pem file to a safe place.
- Go to "Settings -> Configure KVIrc"
- Go to "Connection -> advanced"
- On the Tab "SSL" check "Use ssl certificate" and "Use SSL private key' and point both to the Rizon.pem file you created.
- Change your connection settings and enable the ssl option.
Move the Rizon.pem file to a safe place. Make sure you can connect using ssl. If not, then go here http://www.mirc.com/ssl.html
- Go to "Main Options Menu -> Connect -> Options"
- Click on the SSL button, if there isn't one, then you didn't install ssl properly.
- Click on the empty box below "Private Key File", navigate to where you placed your Rizon.pem and select it.
- Do the same for "Certificate Chain File"
XChat uses the pem file that corresponds with the name of the network under "Network list". If irc.rizon.net is named under Rizon, then all you have to do is move the Rizon.pem file to
C:\Users\xxx\AppData\Roaming\X-Chat 2. If it's not named "Rizon", then you will have to either rename the .pem file, or rename the network that irc.rizon.net is listen under, so they match eachother. Once you are done with that:
- Go to Xchat menu and select "Network List"
- Find Rizon and select "edit".
- Select the boxes "Use SSL for all the servers on this network" and "Accept invalid SSL certificate".
- Click "Close" and then click "Connect".
- quit weechat
- move Rizon.pem to
- make the following options look like this:
# changing the port to 6697 or 9999 is what matters rizon.addresses = "irc.rizon.net/6697" rizon.ssl = on rizon.ssl_cert = "%h/ssl/Rizon.pem" # 2048 is the default anyway... *shrugs* rizon.ssl_dhkey_size = 2048 # weechat will refuse to connect if ssl_verify # is on - untrusted certificate issuer or something rizon.ssl_verify = off
- Move the cert to
- Use the command
/server add -ssl -ssl_cert ~/.irssi/certs/Rizon.pem -network Rizon irc.rizon.net 6697
- ensure the Cert module is loaded
- Move your certificate to
When you connect to Rizon, you should see something like:
* *** Connected securely via SSLv3 AES256-SHA-256 * *** Your client certificate fingerprint is xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx * Welcome to the Rizon Internet Relay Chat Network Rebel_n00b
If you see that, that means you have configured everything correctly.
Add the certificate fingerprint to NickServ
First, identify yourself through services with
/msg NickServ IDENTIFY password.
Next, just copy and paste this line
/msg NickServ ACCESS ADD FINGERPRINT
Disable whatever auto-authentication you had with NickServ before you saw this tutorial, and reconnect. If it worked you will be identified by services automatically via the fingerprint.
