CSR, CSR Generation, SSL Server Certificate, Tomcat These instructions will show you how to create a Certificate Signing Request (“CSR”) in Tomcat using the keytool command. Tomcat’s “keystore” is a file to hold security-related items like keys and certificates. Tomcat uses Java’s.jks (“Java KeyStore”) format for keystore files. Configuring SSL with Tomcat To enable encrypted connections with Tomcat, the HTTPS connector must be configured using the following procedure: Locate the server.xml file for the Tomcat installation (generally this would be conf/server.xml within the Tomcat directory). Enabling SSL via Tomcat with an existing certificate. Written by Ryan Griffith Updated over a week ago Import the certificate and private key. Enter the following. An SSL (Secure Socket Layer) certificate is used to verify the ownership of the web server the client is connecting to using the HTTPS protocol. You normally buy an SSL certificate from a Certificate Authority or CA such as Verisign, DigiCert etc and install it on your web server (in this case the Tomcat web server).

Import the certificate and private key

1. Enter the following command from the terminal:


Add ssl to tomcat
  • <path/to/cert> is the full path to the location of your certificate.

  • <path/to/key> is the full path to the location of your private key

  • <alias> is the name you wish to use to identify this keystore entry

  • <keystore-name> is the name you wish to use for your new keystore

2. When prompted, enter the passphrase for your key (if you have one)

3. When prompted, provide a password to use for the keystore

Import the root certificates

Note: this step may or may not be necessary for your certificate

1. Change into the jre/bin directory of your Java installation

2. Enter the following command:


  • <your_keystore_filename> is the full path to the location of your keystore

  • <filename_of_the_chain_certificate> is the full path to your chain certificate

3. When prompted, enter the password for your keystore in order to import the chain certificate

Configure Tomcat's server.xml file

1. Edit the file tomcat/conf/server.xml (found within the Cascade CMS directory)

2. Uncomment the SSL/TLS HTTP/1.1 Connector and add the following parameters:


  • <alias> is the name you chose to use to identify your keystore entry above

  • <path/to/keystore> is the full path to the location of the keystore you created above

  • <keystore_pass_from_above> is the keystore password you had set above

NOTE: To prevent issues, we recommend that you avoid using any of the following characters in your keystore password: & < > ' '

Here are step-by-step instructions to Install SSL Certificate on Apache Tomcat server

Released 19 years ago, Apache Tomcat server is one of the most popular choices when it comes to open-source servers. Among all Java application servers, Tomcat occupies a staggering 63.9% of the market share. But we’re not here to sing the praises of Tomcat, are we? So, let’s get to the SSL certificate installation process in Tomcat without wasting much time.

Get SSL for your Apache Tomcat server and save up to 71%

Authenticate your Tomcat server using a reliable SSL certificate and set up a secure communication channel.

Before you begin…

You must make sure that the certificate files that you received from your certificate provider are stored in the same server directory as the keystore you created at the time of CSR generation.

If you’ve taken care of this requirement, you’re good to go.

Here’s how to install SSL in Tomcat

Step 1: Root Certificate Installation

First and foremost, you’ll need to install your root certificate file on your server. You’ll need to install the following command to do it:

keytool -import -trustcacerts -alias root -file RootCertFileName.crt -keystore keystore.key

Now, you’ll receive a message that says “Certificate already exists in system-wide CA keystore under alias <…> Do you still want to add it to your own keystore? [no]:”. Choose Yes. If the installation was successful, a “Certificate was added to keystore” message will be displayed on your screen.

Step 2: Intermediate Certificate Installation

Depending on your CA, you may or may not need to do this step. That’s because not every CA provides an intermediate certificate. You only need to install an intermediate certificate if you have received one. Run the following command to do so:

keytool -import -trustcacerts -alias intermediate -file IntermediateCertFileName.crt -keystore keystore.key

A “Certificate was added to keystore” message will be displayed if this went well.

Step 3: Primary Certificate Installation

Type in the following command to install the primary certificate:

keytool -import -trustcacerts -alias tomcat -file PrimaryCertFileName.crt -keystore keystore.key

Once done successfully, you should see a “Certificate reply was installed in keystore” message on your screen.

Step 4: SSL Connector Configuration

Once all these steps are done successfully, you’ll need to configure your SSL connector. Without this, an SSL/TLS connection cannot be established. So, keep a close eye on this part.

The things you’ll need to do are to change the file location and password.

Bind Apache Tomcat To Wildcard Ssl Certificate

  • First, copy your keystore file to the home directory

Note: On Unix and Linux systems, the home directory would be /home/user_name/ while it would be Settingsuser_name on Microsoft Windows systems.

  • Open ${CATALINA_HOME}/conf/server.xml file in a text editor (e.g. Notepad)
  • You’ll need to uncomment the SSL Connector Configuration
  • Verify that the Connector Port is 443. If not, change it to 443.
  • Finally, check whether the keystorePass matches with the keystore password. Also, confirm if the keystoreFile consists of the file and pathname of the keystore.

All done? The connector will look like:

<Connector className=”org.apache.catalina.connector.http.HttpConnector” port=”8443″ minProcessors=”5″ maxProcessors=”75″ enableLookups=”true” acceptCount=”10″ debug=”0″ scheme=”https” secure=”true”>

Tomcat Ssl_error_weak_server_ephemeral_dh_key

<Factory className=”” clientAuth=”false” protocol=”TLS” keystoreFile=”/working/mykeystore” keystorePass=”password”/>

Tomcat Install Ssl

  • Save the changes to server.xml file
  • Restart your Tomcat server

Tomcat Sslprotocol= Tlsv1.2

If everything went smoothly, your Tomcat server should now have an SSL/TLS certificate as your gatekeeper.
