Automating SSL configurations using scripting
SSL configuration is needed for the product to perform SSL connections with other servers. We can configure SSL through the administrative console. But AdminTask provides an automated way to create an SSL configuration.
The wsadmin tool must be running. See topic about starting the wsadmin scripting client.
AdminTask can be used in interactive mode and batch mode. For automation, use the batch mode options. AdminTask batch mode can be called in a Jython script. Interactive mode steps through all parameters the task needs, required ones are marked with an asterisk (*). Before the interactive task runs the task, it echoes the batch mode syntax of the task to the screen. The syntax can help you write batch mode scripts.
An SSL configuration requires the following attributes:
- A keystore
- Default client certificate alias
- Default server certificate alias
- Truststore
- The handshake protocol
- The ciphers needed during handshake
- Supporting client authentication or not
To automate the creation of an SSL configuration, we might need to create some of the attribute values, such as the keystore, truststore, key manager, and trust managers.
Tasks
- Create or change an SSL configuration.
To create an SSL configuration, use the AdminTask createSSLConfig command. To change an SSL configuration, use the AdminTask modifySSLConfig command.
- Interactive mode:
Interactive mode steps you through all attributes and displays the default value of the attribute, if there is one. The default is in brackets [] on the prompt line. The actual flag used in batch mode is in parentheses () on each prompt line. If we are using the default value, then the flag does not display on the batch command line.
Use Jacl:
$AdminTask createSSLConfig -interactive- Jython:
AdminTask.createSSLConfig ('[interactive]')Example output:

- Batch mode:
Use Jacl:
$AdminTask createSSLConfig {-alias testSSLConfig -scopeName (cell):HOSTNode01Cell:(node):HOSTNode01 -clientKeyAlias clientCert -serverKeyAlias serverCert -trustStoreName testTrustStore -trustStoreScopeName (cell):HOSTNode01Cell:(node):HOSTNode01 -keyStoreName testKeyStore -keyStoreScopeName (cell):HOSTNode01Cell:(node):HOSTNode01 -keyManagerName IbmX509 -keyManagerScopeName (cell):HOSTNode01Cell:(node):HOSTNode01}- Jython:
AdminTask.createSSLConfig ('[-alias testSSLConfig -scopeName (cell):HOSTNode01Cell:(node):HOSTNode01 -clientKeyAlias clientCert -serverKeyAlias serverCert -trustStoreName testTrustStore -trustStoreScopeName (cell):HOSTNode01Cell:(node):HOSTNode01 -keyStoreName testKeyStore -keyStoreScopeName (cell):HOSTNode01Cell:(node):HOSTNode01 -keyManagerName IbmX509 -keyManagerScopeName (cell):HOSTNode01Cell:(node):HOSTNode01]')Example output:
(cells/HOSTNode01Cell|security.xml#SSLConfig_1137687301834)- Create a keystore or truststore.
The keystore and truststore might exist or a new one might need to be created. To create a new keystore or truststore, use the AdminTask createKeyStore command. It creates a keystore file and stores the configuration object in the system configuration. A truststore is a keystore that usually has only signer certificates in it. To create a keystore, enter:
- Jacl:
$AdminTask createKeyStore {-keyStoreName testKeyStore -keyStoreType PKCS12 -keyStoreLocation $(USER_INSTALL_ROOT)\testKeyStore.p12 -keyStorePassword abcd -keyStorePasswordVerify abcd -keyStoreIsFileBased true -keyStoreReadOnly false}- Jython:
AdminTask.createKeyStore ('[-keyStoreName testKeyStore -keyStoreType PKCS12 -keyStoreLocation $(USER_INSTALL_ROOT)\testKeyStore.p12 -keyStorePassword abcd -keyStorePasswordVerify abcd -keyStoreIsFileBased true -keyStoreReadOnly false]')
To populate the keystore with certificates, see the topic about managing certificates with the administrative console and AdminTask. The keystore and truststore are required to create an SSL configuration. Use the -keyStoreName and -trustStoreName flags on the createSSLConfig command. We can add their scopes with the -keyStoreScope and -trustStoreScope flags.
- Create a key manager.
Key managers are used to determine how a certificate is selected. The IbmX509 key manager is in the security configuration by default. If we need a different key manager, then use the AdminTask createKeyManager command to create it.
To create a key manager, enter:
- Jacl:
$AdminTask createKeyManager {-name testKeyManager -scopeName (cell):HOSTNode01Cell:(node):HOSTNode01 -provider IBMJSSE2 -algorithm specialAlgorithm }- Jython:
AdminTask.createKeyManager ('[-name testKeyManager -scopeName (cell):HOSTNode01Cell:(node):HOSTNode01 -provider IBMJSSE2 -algorithm specialAlgorithm]')
To supply a key manager on the AdminTask createSSLConfig command, use the -keyManagerName flag along with the -keyManagerScopeName flag.
- Create a trust manager.
Trust managers are used to determine how trust is established during SSLcommunication. The IbmX509 and IbmPKIX are trust managers in the security configuration by default. If a different or additional trust manager is needed, then use the AdminTask createTrustManager command to create it. To create a trust manager, enter:
- Jacl:
$AdminTask createTrustManager {-name testTrustManager -scopeName (cell):HOSTNode01Cell:(node):HOSTNode01 -provider IBMJSSE2 -algorithm specialAlgorithm }- Jython:
AdminTask.createTrustManager ('[-name testTrustManager -scopeName (cell):HOSTNode01Cell:(node):HOSTNode01 -provider IBMJSSE2 -algorithm specialAlgorithm]')
The SSL configuration can have multiple trust managers. To supply multiple trust managers, give a colon (:) separated list of the trust manager configuration IDs with the -trustManagerObjectNames flag. When we create a trust manager the configuration object ID is returned. To get a list of trust managers object IDs, use the listTrustManagers command of the AdminTask object with the -displayObjectName flag set to true. For example:
wsadmin>$AdminTask listTrustManagers -interactive List Trust Managers List trust managers. Management Scope Name (scopeName): Display list in ObjectName Format (displayObjectName): [false] true List Trust Managers F (Finish) C (Cancel) Select [F, C]: [F] Inside generate script command WASX7278I: Generated command line: $AdminTask listTrustManagers {-displayObjectName true } IbmX509(cells/IBM-0AF8DABCF16Node01Cell|security.xml#TrustManager_IBM-0AF8DABCF16Node01_1) IbmPKIX(cells/IBM-0AF8DABCF16Node01Cell|security.xml#TrustManager_IBM-0AF8DABCF16Node01_2)
