By default, Tomcat will assume the password as "changeit". You can change the password, but then you need to set the keystorePass in Tomcat's configuration file. Regardless, the password for both the keystore and the cert MUST be the same. Store the keystore in a safe place such as Tomcat's configuration folder: 
/etc/tomcat5.5
Next edit Tomcat's server configuration file: 
/etc/tomcat5.5/server.xml
Locate the SSL connector declaration, uncomment it, and add the keystoreFile path:

<Connector port="8443" maxHttpHeaderSize="8192"

Save the changes and restart Tomcat: 
sudo /etc/init.d/tomcat5.5 restart
You should be good to go at this point. Launch your favorite web browser and go to https://localhost:8443.

Now you are secure and ready to rock.]]> Recently I needed to generate a self-signed SSL cert for Apache Tomcat 5.5 on my Ubuntu Linux server. The basic process is to create a Java keystore with the self-signed cert, change Tomcat’s configuration file, and restart the server. Here’s how I did it:

$ keytool -genkey -alias tomcat -keyalg RSA -keystore mycert.jks
Enter keystore password:  changeit
