In Fusion Middleware 11g/12c, user can very easily protect their services using OWSM policies. A number of these policies are message protection policies, And to invoke these services, client need to set up OPSS keystore service properly to be picked by owsm. Following is an attempt to automate the steps using DemoCA cert available with WLS installation.

The automated script executes the following steps:

1) java utils.CertGen -certfile ClientPublicCertificate -keyfile ClientPrivateKey -keyfilepass internalPassword -cn hostName 

2) Create client keystore with client key-certificate pair

java utils.ImportPrivateKey -keystore suppliedLocation -storepass suppliedPassword -certfile ClientPublicCertificate.der -keyfile ClientPrivateKey.der -keyfilepass internalPassword -alias suppliedAlias -keypass suppliedPassword 

3) Now add the root CA to the client keystore

keytool -importcert -file ${rootca.location}/CertGenCA.der -keystore default-keystore.jks -storepass welcome1 -alias wlsdemoca

4) Add the service’s public certificate to the client keystore.

keytool -importcert -file ServerPublicCertificate.der -alias serverkey -keystore default-keystore.jks -storepass welcome1

(Note)

Latest version of OWSM can expose public certificate of service directly in the service WSDL through its Service Identity Certificate Extension 

Hence, this step is optional depending on your settings.
In older releases, the service’s public certificate had to be added to the client keystore; If the recipient alias property (keystore.recipient.alias) on the client was not explicitly set, then this certificate would need to have be added under the the alias “orakey”.

5) Add options to credential store (CWALLET.SSO) so as to access keys/certificates from keystore

%MW_HOME%/oracle_common/common/bin/.wlst.sh
connect('weblogic','weblogic1','t3://localhost:7101')
createCred(map="oracle.wsm.security", key="keystore-csf-key", user="n/a", password="welcome1", desc="keystore access password")
createCred(map="oracle.wsm.security", key="sign-csf-key", user="clientkey", password="welcome1", desc="signing key alias and password")
createCred(map="oracle.wsm.security", key="enc-csf-key", user="clientkey", password="welcome1", desc="encryption key alias and password")

If you are running web services as well on a different server, you can set up keystore for server following the similar steps as well. Or if you can use the DemoIdentity available with default installation of WLS server as well. Following steps, will let you use DemoIdenity.jks at server side.

1) Copy DemoIdentity.jks to /config/fmwconfig and rename it to default-keystore.jks Why rename? (owsm reads the keystore from the keystore service defined in jps-config.xml located at same location). If you want to use different name, modify the entry in jps-config.xml.

You will need to modify the keystore name in following entry of jps-config.xml

      <property name="keystore.type" value="JKS"/>
      <property name="keystore.csf.map" value="oracle.wsm.security"/>
      <property name="keystore.pass.csf.key" value="keystore-csf-key"/>
      <property name="keystore.sig.csf.key" value="sign-csf-key"/>
      <property name="keystore.enc.csf.key" value="enc-csf-key"/>

2) DemoIdentity.jks will have a privatekey, and public certificate. It does not have CA certificate in it. Import the same.

keytool -importcert -file $WL_HOME/server/lib/CertGenCA.der -keystore default-keystore.jks -storepass DemoIdentityKeyStorePassPhrase

DemoIdentityKeyStorePassPhrase is the password of DemoIdentity.jks

3) Restart the server.

3) Create entries into the domain wallet (cwallet.sso) as below using wlst command:

createCred(map="oracle.wsm.security", key="keystore-csf-key", user="n/a", password="DemoIdentityKeyStorePassPhrase", desc="Keystore key.Password will be used to open the keystore")
createCred(map="oracle.wsm.security", key="sign-csf-key", user="demoidentity", password="DemoIdentityPassPhrase",desc="demoidentity is the private key in your keystore")
createCred(map="oracle.wsm.security", key="enc-csf-key", user="demoidentity", password="DemoIdentityPassPhrase",desc="")

DemoIdentityPassPhrase is the password of private key in DemoIdentity.jks

DemoIdentityPassPhrase is the password of private key in DemoIdentity.jks

4) Export the public key of the certificate for clients to use.
