SSL Configuration using Certificate

LogicalDOC embeds the Tomcat application server and it can be configured to support the encrypted protocol HTTPS. This is useful when you want to expose the program on the Internet.

Please be aware that this procedure is not coverded by the standard support contract. In case you want this matter to be handled professionally, please write to sales@logicaldoc.com for a quote.

Basically you only have to follows the steps described in the Apache how-to at SSL Configuration HOW-TO What follows is a re-visioned extract from that how-to

Preparing the certificate (skip this step if you already have your own SSL certificate)

To install and configure SSL support on Tomcat, you need the following things:

• The file of your server certificate (the format must be PEM-encoded)
• The file containing the certificate chain associated with the server certificate (the format must be PEM-encoded)
• The file that contains the server private key (the format must be PEM-encoded)

You get those 3 files as a result of the certificate issuing procedure.

Most of the times you server's certificate and the chain file are in .crt, .cer or .der format. In this case please convert them openssl:
openssl x509 -in cert.crt -out cert.pem
openssl x509 -in cert.cer -out cert.pem
openssl x509 -in cert.der -out cert.pem

In the same way, probably your secret key is in .txt format, so please convert it into .pem using openssl:
openssl rsa -in privkey.txt -out privkey.pem

We suggest to put your .pem files in <LDOC_HOME>/conf and in any case outside the tomcat folder.

Edit the Tomcat configuration file

The final step is to configure your secure socket in the <LDOC_HOME>/tomcat/conf/server.xml file, where <LDOC_HOME> represents the base directory for the LogicalDOC installation. An example <Connector> element for an SSL connector looks something like this:

   <Connector protocol="org.apache.coyote.http11.Http11NioProtocol"
              port="8443" maxThreads="200"
              URIEncoding="UTF-8" server="Undisclosed/8.41"
              scheme="https" secure="true" SSLEnabled="true">
              <SSLHostConfig>
                <Certificate certificateFile="${catalina.home}/../conf/cert.pem"
                             certificateKeyFile="${catalina.home}/../conf/privkey.pem"
                             certificateChainFile="${catalina.home}/../conf/chain.pem" />
              </SSLHostConfig>
   </Connector>
   		

replace <LDOC_HOME> with the installation path of LogicalDOC

LogicalDOC application will be updated from time to time so it is not safe to maintain the keystore inside the tomcat/ folder, please put your .pem files inside the conf/ folder of the LogicalDOC installation path.

The port attribute (default value is 8443) is the TCP/IP port number on which Tomcat will listen for secure connections. You can change this to any port number you wish.

If you change the port number here, you should also change the value specified for the redirectPort attribute on the non-SSL connector. This allows Tomcat to automatically redirect users who attempt to access a page with a security constraint specifying that SSL is required.

After completing these configuration changes, you must restart LogicalDOC as you normally do, you should be able to access via SSL. For example, try:

   https://localhost:8443

and you should see the usual login page.

Use directly a .P12 file

    <Connector protocol="org.apache.coyote.http11.Http11NioProtocol"
               port="8443" maxThreads="200" 
               URIEncoding="UTF-8" server="Undisclosed"
               maxHttpHeaderSize="16384"			   
               scheme="https" secure="true" SSLEnabled="true"
			   clientAuth="false" 
			   sslProtocol="TLSv1.1+TLSv1.2+TLSv1.3"
               keystoreFile="${catalina.home}/../conf/mycert.p12"
			   keystoreType="PKCS12"
               keystorePass="certpasswd"  />
