How to create SSL certificate

Steps to setup SSL Certificate

1.Create a certificate keystore by executing the following command:
Windows:%JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA
Unix:$JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA

Put in the details as prompted for and remember to keep the same password in the whole process.
On windows the .keystore file will get created in the users section ie in my case C:\Documents and Settings\admin

2.Uncomment the part below the following statement in the TOMCAT_HOME/conf/server.xml
Add the keystoreType , keystoreFile , keystorePass variable to the same tab
The section should look something like this
< maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" disableUploadTimeout="true" acceptCount="100" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" keystoreType="JKS" keystoreFile="C:\Documents and Settings\admin\.keystore" keystorePass="PASSWORD"/>
3.Restart TOMCAT

SSL is configured

  • “It doesn’t matter how many times I have to click, as long as each click is a mindless, unambiguous choice.”
  • “Get rid of half the words on each page, then get rid of half of what is left.”
