Generating Certificates

Edit online

Tto obtain a real SSL certificate, you must first generate a CSR (Certificate Signing Request). A CSR is a body of text that contains information specific to your company and domain name. This is a public key for your server.

The Java keytool utility can be used to create and handle certificates. Keytool stores all keys and certificates in a keystore. For a detailed description of keytool please see its documentation.

Step 1: Create a keystore

Use the keytool to create a keystore with a private/public keypair.

keytool -genkey -keyalg "RSA" -keystore keystore -storepass password -validity 360

You will be prompted for information about your organization. Please note that when it asks for "User first and last name", please specify the hostname that Universal Messaging will be running on ( e.g. www.yoursite.com ).

Step 2: Create a certificate request

Use the keytool to create a certificate request.

keytool -certreq -keyalg "RSA" -file your.host.com.csr -keystore keystore

This will generate a file containing a certificate request in text format. The request itself will look something like this :


-----BEGIN NEW CERTIFICATE REQUEST-----

 -----END NEW CERTIFICATE REQUEST-----

Step 3: Submit your certificate request to a certificate supplier

Certificate vendors will typically ask you to paste the certificate request into a weborder form. This will be used as a public key to generate you private key. Please include the (BEGIN and END) tags when you paste the certificate request.

Please note that a cert of PKCS #7 format is required so that it can be imported back into keytool. (step 4)

The certificate vendor will then provide you with a certificate which that will look something like this:

Please paste this certificate into a file called your.host.com.cer [Note. please include the (BEGIN and END) tags]

Step 4: Store the certificate in your keystore

Use the keytool to store the generated certificate :

keytool -keystore keystore -keyalg "RSA" -import -trustcacerts -file your.host.com.cer

After step 4 is completed, you now have a Universal Messaging server keystore and can add an SSL interface as described in Creating an SSL-Enabled Interface.

Note that if you completed steps 1 to 4 for test certificates then you will also need to create a store for the CA root certificate as Universal Messaging will not be able to start the interface until it validates where it came from. Certificate vendors typically provide test root certificates which are not recognized by browsers etc. In this case you will need to add that cert to another store and use that as your cacert. When specifying certificates for a Universal Messaging SSL interface this would be specified as the Trust Store Path in the certificates tab.

If you are using anonymous SSL then you will have to provide this cacert to clients also as this will not be able to validate the Universal Messaging certificate without it. Please see the Security section of our Concepts guide for more information on configuring Universal Messaging clients to use certificates.
