Before you begin, ensure that you have installed Java 1.6 installed8 or a higher version.

1. Download the WSO2 product to any location (e.g., <HOME>/user/<product-pack> folder).

2. To sign the JARs in your product, you need a key. Generate it using the keytool command as follows:

   Code Block
   keytool -genkey -alias signFiles -keyalg RSA -keystore signkeystore.jks -validity 3650 -dname "CN=Sanjeewa,OU=Engineering, O=WSO2, L=Colombo, ST=Western, C=LK"Enter keystore password: Re-enter new password: Enter key password for (RETURN if same as keystore password)

   The default keystore of the WSO2 products is wso2carbon.jks, which is in the <PRODUCT_HOME>/repository/resources/security folder. It is used for signing JARs.

3. Import the signFiles public key certificate that you created earlier to wso2carbon.jks. The sample below shows the security policy file referring the signer certificate from the wso2carbon.jks file:

   Code Block

   $ keytool -export -keystore signkeystore.jks -alias signFiles -file sign-cert.cer   $ keytool -import -alias signFiles -file sign-cert.cer -keystore repository/resources/security/wso2carbon.jks Enter keystore password: Owner: CN=Sanjeewa, OU=Engineering, O=WSO2, L=Colombo, ST=Western, C=LK Issuer: CN=Sanjeewa, OU=Engineering, O=WSO2, L=Colombo, ST=Western, C=LK Serial number: 5486f3b0 Valid from: Tue Dec 09 18:35:52 IST 2014 until: Fri Dec 06 18:35:52 IST 2024 Certificate fingerprints: MD5: 54:13:FD:06:6F:C9:A6:BC:EE:DF:73:A9:88:CC:02:EC SHA1: AE:37:2A:9E:66:86:12:68:28:88:12:A0:85:50:B1:D1:21:BD:49:52 Signature algorithm name: SHA1withRSA Version: 3 Trust this certificate? [no]: yes Certificate was added to keystore

4. Prepare the scripts to sign the JARs and grant them the required permission. For example, the signJar.sh script given below can be used to sign each JAR file separately or you can use the signJars.sh script, which runs a loop to read all JARs and sign them.

   Code Block
   language java title signJar.sh script
   #!/bin/bash set -e jarfile=$1 keystore_file="signkeystore.jks" keystore_keyalias='signFiles' keystore_storepass='wso2123' keystore_keypass='wso2123' signjar="$JAVA_HOME/bin/jarsigner -sigalg MD5withRSA -digestalg SHA1 -keystore $keystore_file -storepass $keystore_storepass -keypass $keystore_keypass" verifyjar="$JAVA_HOME/bin/jarsigner -keystore $keystore_file -verify" echo "Signing $jarfile" $signjar $jarfile $keystore_keyalias echo "Verifying $jarfile" $verifyjar $jarfile # Check whether the verification is successful. if [ $? -eq 1 ] then echo "Verification failed for $jarfile" fi

   Code Block
   language java title signJars.sh script
   #!/bin/bash if [[ ! -d $1 ]]; then echo "Please specify a target directory" exit 1 fi for jarfile in `find . -type f -iname \*.jar` do ./signJar.sh $jarfile done

5. Execute the following commands to sign the JARs in your product:

   Code Block
   ./signJars.sh /HOME/user/<product-pack>

   Tip
   Every time you add an external JAR to the WSO2 product, sign them manually using the above instructions for the Java Security Manager to be effective. You add external JARs to the server when extending the product, applying patches etc.

6. Open the startup script in the <PRODUCT_HOME>/bin folder. For Linux, it is wso2server.sh. 

7. Add the following system properties to the startup script and save the file:

   Code Block
   -Djava.security.manager=org.wso2.carbon.bootstrap.CarbonSecurityManager \ -Djava.security.policy=$CARBON_HOME/repository/conf/sec.policy \ -Drestricted.packages=sun.,com.sun.xml.internal.ws.,com.sun.xml.internal.bind.,com.sun.imageio.,org.wso2.carbon. \ -Ddenied.system.properties=javax.net.ssl.trustStore,javax.net.ssl.trustStorePassword,denied.system.properties \

8. Create a sec.policy file with the required security policies in the <PRODUCT_HOME>/repository/conf folder and start the server. Starting the server makes the Java permissions defined in the sec.policy file take effect. The following is a sample of how this file would look.

   Code Block
   language java
