Using CA signed certificate for Confluence
Asked by Lorenze Larot:

Hello,

I'm new to confluence (I just heard about it Friday last week ![laugh](/html/@BEA1CC333F4D830F5303329D7DC07DE4/images/emoticons/laugh.png "laugh")) and I am tasked to install a CA signed certificate to confluence. I found to this guide <https://confluence.atlassian.com/doc/running-confluence-over-ssl-or-https-161203.html> to be helpful. I just want to ask a few clarifications.

* I already have the CA signed certificate already, (.cer file), should I just simply import this to the keystore and proceed with step 2 on the guide?

Thank you in advance for any response.

Best,

Renz

So I was able to import my certificate to the keystore and gone through steps 2 3 and 4. However, when I tried to access [https://confluence.mydomain.com:8443](https://confluence.mydomain.com:443) its showing an error:

"ERR_SSL_VERSION_OR_CIPHER_MISMATCH.

My server.xml looks like the one below.

\<Connector port="8443" maxHttpHeaderSize="8192"  
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"  
enableLookups="false" disableUploadTimeout="true"  
acceptCount="100" scheme="https" secure="true"  
clientAuth="false" sslProtocol="TLS" SSLEnabled="true"  
URIEncoding="UTF-8" keystorePass="mypassword"  
keystoreFile="\<C:\\Program Files\\Atlassian\\Confluence\\jre\\lib\\security\\cacerts\>"/\>

Am I missing any steps here?

Any response will be much appreciated.

Thanks,

renz

body: Hello @Steven Behnke,

Thanks for your response. What I did was simply run the command below. Should I create a new keystore and import my certificate to the newly created keystore and have my server.xml points to the keystore path? Sorry for the noob question.

Thanks

```
C:\&gt;keytool ?import ?keystore ..\lib\security\cacerts ?alias newcertificate ?storepass changeit ?noprompt ?trustcacerts ?file c:\new_certificate.crt
```

body: Okay: The issue here is that you don't understand what you're really doing. Sorry for being so blunt. This isn't easy to explain without knowing more detail about your OS and system information. I'm familiar with the Linux process but the Windows process *should* be the same.

You need to pair the certificate and the key under an alias in a new keystore. **This is how you secure your server!** Your server's *key* PLUS your purchased certificate is your security! When you import your certificate, you need to make sure it trusts your CA Certs file, which you should have already added to or modified with the rest of the trust chain. Alternatively you should be able to import all of the chain into your new keystore, I think.

I don't think that adding all the certificates to the CA Certs file will work at all.
