Managing SSL Certificates

Managing SSL Certificates

Obtaining an SSL Certificate

The platform provides a default self-signed certificate which is used by the Application Server.

To obtain and install your own SSL Certificate, make a request to a Certificate Authority (CA). An SSL certificate authenticates a website to a web browser, part of a security protocol to manage secure data exchange.

The CA will accept your Certificate Signing Request and generate a certificate which identifies your website as a secured website.

To create a Certificate Signing Request (CSR)

1. Create a keystore and a private key:

cd {install_dir}/tomcat/conf/RN
keytool -genkey -alias tomcat -keyalg RSA -keysize 2048 -keystore {keystore_filename}

2. Create a CSR from the keystore

keytool -certreq -keyalg RSA -alias tomcat -file certreq.csr 
        -keystore {keystore_filename}

3. Submit the resulting file, certreq.csr, to the CA to obtain a certificate.
(When the certificate arrives, you are ready for the next step of steps.)

To Install the Certificate Obtained from the CA

Once you have obtained a certificate, you need to import it into the keystore.

But first, in addition to your certificate, the CA might provide a Chain/Root Certificate, which must also be imported. If you have received a chain certificate from the CA, then:

1. Copy the contents of the chain certificate into a file called chain

2. Import the chain certificate into your keystore:

keytool -import -alias root -keystore {keystore_filename} 
        -trustcacerts -file chain

When the chain certificate (if any) has been imported, you are ready for the final step:

3. Import the certificate received from the CA:

keytool -import -alias tomcat -keystore {keystore_filename} 
        -trustcacerts -file {certificate_filename}

Replacing the Default SSL Certificate

To replace the certificate:

1. Add the new certificate to this directory:

   {install_dir}/tomcat/conf/RN

2. Edit {install_dir}/tomcat/conf/server.xml file
3. Replace the following line:

   keystoreFile="conf/RN/thirdParty" keystorePass="algrsa"

   with:

   keystoreFile="conf/RN/your_certficate_file_name"

   keystorePass="your_password_for_certificate_store"

4. Save the file
5. Restart the application server

The Application Server will now use your certificate file for communication over https.
