Configuring Keystores in WSO2 Products

After you have created a new keystore and updated the client-truststore.jks file, you must update a few configuration files in order to make the keystore work. Note that keystores are used for multiple functions in WSO2 products, which includes securing the servlet transport, encrypting confidential information in configuration files, etc. Therefore, you must update the specific configuration files with the relevant keystore information. For example, you may have separate keystores for the purpose of encrypting passwords in configuration files, and for securing the servlet transport.

The wso2carbon.jks keystore file, which is shipped with all WSO2 products, is used as the default keystore for all functions. However, in a production environment, it is recommended to create new keystores with keys and certificates.

If you want an easy way to locate all the configuration files that have references to keystores, you can use the grep command as follows:

Open a command prompt and navigate to the <PRODUCT_HOME>/repository/conf/ directory where your product stores all configuration files.
Execute the following command: grep -nr ".jks" .

The configuration files and the keystore files referred to in each file are listed out. See an example of this below.

./axis2/axis2.xml:260:                <Location>repository/resources/security/wso2carbon.jks</Location>
./axis2/axis2.xml:431:                <Location>repository/resources/security/wso2carbon.jks</Location>
./carbon.xml:316:            <Location>${carbon.home}/repository/resources/security/wso2carbon.jks</Location>
./carbon.xml:332:            <Location>${carbon.home}/repository/resources/security/wso2carbon.jks</Location>
./identity.xml:180:				<Location>${carbon.home}/repository/resources/security/wso2carbon.jks</Location>
./security/secret-conf.properties:21:#keystore.identity.location=repository/resources/security/wso2carbon.jks

Configuring the primary keystore

The primary keystore mainly stores the keys certifying SSL connections to Carbon servers and the keys for encrypting administrator passwords as well as other confidential information. The Keystore element in the carbon.xml file, stored in the <PRODUCT_HOME>/repository/conf/ directory must be updated with details of the primary keystore. The default configuration is shown below.

<KeyStore>
	<Location>${carbon.home}/resources/security/wso2carbon.jks</Location>
	<Type>JKS</Type>
	<Password>wso2carbon</Password>
	<KeyAlias>wso2carbon</KeyAlias>
	<KeyPassword>wso2carbon</KeyPassword>
</KeyStore>
 
<TrustStore>
	<!-- trust-store file location -->
	<Location>${carbon.home}/repository/resources/security/client-truststore.jks</Location>
	<!-- trust-store type (JKS/PKCS12 etc.) -->
	<Type>JKS</Type> 
	<!-- trust-store password -->
	<Password>wso2carbon</Password>
</TrustStore>

You need to add in the following information:

<jks store password>
<jks alias>
<jks store password(same as the key password)>

Configuring a keystore for Java permissions

The sec.policy file stored in the <PRODUCT_HOME>/repository/conf/ directory should be updated with details of the keystore used for enabling Java permissions for your server. The default configuration is shown below.

keystore "file:${user.dir}/repository/resources/security/wso2carbon.jks", "JKS";
