The instructions on this page explain how plain text passwords in configuration files can be encrypted using the secure vault implementation that is built into WSO2 products. Note that you can customize the default secure vault configurations in the product by implementing a new secret repository, call back handler etc. Read more about the Secure Vault implementation in WSO2 products.

1. Download and install a WSO2 product.
2. Open a command prompt and navigate to the <PRODUCT_HOME>/bin folder.

3. You must first enable the Cipher tool for the product by executing the following command:

   Code Block
   sh ciphertool.sh -Dconfigure

   Note
   If you are using the cipher tool for the first time, this command will first initialize the tool for your product. The tool will then encrypt any plain text passwords that are specified in the cipher-text.properties file for automatic encryption.

4. Now, you can start encrypting the admin password manually. Execute the Cipher tool using the following command:

   Code Block
   sh ciphertool.sh

5. You will be asked to enter the primary key password, which is by default 'wso2carbon'. Enter the password and proceed.

6. You will now be asked to enter the plain text password that you want to encrypt. Enter the following element as the password and proceed:

   Code Block
   Enter Plain Text Value :admin

   Info
   Note that in certain configuration files, the password that requires encryption may not be specified as a single value as it is in the log4j.properties file. For example, the jndi.properties file used in WSO2 ESB contains the password in the connection URL. In such cases, you need to encrypt the entire connection URL as explained here.

7. You will receive the encrypted value as shown below. For example:

   Code Block
   Encrypted value is: gaMpTzAccMScaHllsZLXspm1i4HLI0M/srL5pB8jyknRKQ2zT7NuCvt1+qEkElRLgwlrohz3lkuE0KFuapXrCSs5pxfGMOLn4/k7dNs2SlwbsG8C++/ ZfUuft1Sl6cqvDRM55fQwzCPfybl713HvKu3oDaJ9VKgSbvHlQj6zqzg=

8. Open the cipher-text.properties file, stored in the <PRODUCT_HOME>/repository/conf/security folder.

9. Add the encrypted password against the secret alias as shown below.

   Code Block
   log4j.appender.LOGEVENT.password=cpw74SGeBNgAVpryqj5/xshSyW5BDW9d1UW0xMZ DxVeoa6RjyA1JRHutZ4SfzfSgSzy2GQJ/2jQIw70IeT5EQEAR8XLGaqlsE5IlNoe9dhyLiPXEPRGq4k/BgUQD YiBg0nU7wRsR8YXrvf+ak8ulX2yGv0Sf8=

10. Now, open the log4j.properties file, stored in the <PRODUCT_HOME>/repository/conf folder and replace the plain text element with the alias of the encrypted value as shown below.

    Code Block
    # LOGEVENT is set to be a LogEventAppender using a PatternLayout to send logs to LOGEVENT .... log4j.appender.LOGEVENT.password=secretAlias:log4j.appender.LOGEVENT.password ....

...

Changing encrypted passwords

To change any password which we have encrypted already, follow the below steps:

1. Be sure to shut down the server.

2. Open a command prompt and go to the <PRODUCT_HOME>/bin directory, where we have stored the ciphertool.sh script.

3. Execute the following command:

   Code Block
   ./ciphertool.sh -Dchange

4. It will prompt for the primary keystore password. Enter the keystore password (which is "wso2carbon" for the default keystore).

5. The alias values of all the passwords that you encrypted will now be shown in a numbered list. 

6. The system will then prompt you to select the alias of the password which you want to change. Enter the list number of the password alias.

7. The system will then prompt you (twice) to enter the new password. Enter your new password.

8. The password should now be changed and encrypted.
