Encoding passwords in files

The purpose of password encoding is to deter casual observation of passwords in server configuration and property files. Use the PropFilePasswordEncoder utility to encode passwords stored in properties files. WebSphere® Application Server does not provide a utility for decoding the passwords. Encoding is not sufficient to fully protect passwords. Native security is the primary mechanism for protecting passwords used in WebSphere Application Server configuration and property files.

About this task

WebSphere Application Server contains several encoded passwords in files that are not encrypted. WebSphere Application Server provides the PropFilePasswordEncoder utility, which you can use to encode passwords. The purpose of password encoding is to deter casual observation of passwords in server configuration and property files. The PropFilePasswordEncoder utility does not encode passwords that are contained within XML or XMI files.

Important: Because the PropFilePasswordEncoder only updates existing property files, if subsequent files are added, such as can occur after installing a new application, this procedure should be rerun for those new files.

Table 1. WebSphere Application Server automatically encodes the passwords in most XML and XMI files. XML and XMI files that contain encoded passwords include the following:

File name	Additional information	Navigation
profile_root/config/cells/cell_name /security.xml	The following fields contain encoded passwords: LTPA password JAAS authentication data User registry server password LDAP user registry bind password Keystore password Truststore password Cryptographic token device password	security > Global security > Apply.

profile_root/config/cells/cell_name/bindings/PolicyTyper/WSSecurity/bindings.xml	The following fields contain encoded passwords: Keystore passwords Key passwords Username token passwords	Services > Policy Sets > Default policy set bindings > Version 6.1 default policy set bindings > WS-Security > Custom properties > Apply.

Note: If you are not using a database, choose: none.
profile_root/config/cells/cell_name/applications/(appName/.../WSSecurity/bindings.xml	WSSecurity/bindings.xml is a JAX-WS WS-Security policy binding file. When it is located in the cell_name/applications path, it is part of an application specific binding. The following fields contain encoded passwords: Keystore passwords Key passwords Username token passwords	Services > service providers or > service clients > resourceName > bindingName > WS-Security > Custom properties > Apply.

Table 2. The PropFilePasswordEncoder utility - Partial File List . You use the PropFilePasswordEncoder utility to encode the passwords in properties files. These files include:

File name	Additional information
profile_root/properties/sas.client.props	Specifies the passwords for the following files: com.ibm.ssl.keyStorePassword com.ibm.ssl.trustStorePassword com.ibm.CORBA.loginPassword
profile_root/properties/sas.tools.properties	Specifies passwords for: com.ibm.ssl.keyStorePassword com.ibm.ssl.trustStorePassword com.ibm.CORBA.loginPassword
profile_root/properties/sas.stdclient.properties	Specifies passwords for: com.ibm.ssl.keyStorePassword com.ibm.ssl.trustStorePassword com.ibm.CORBA.loginPassword
profile_root/properties/wsserver.key
profile_root/profiles/AppSrvXX/properties/sib.client.ssl.properties	Specifies passwords for: com.ibm.ssl.keyStorePassword com.ibm.ssl.trustStorePassword
profile_root/UDDIReg/scripts/UDDIUtilityTools.properties	Specifies passwords for: trustStore.password
profile_root/config/cells/cell_name/sts/SAMLIssuerConfig.properties	The following fields contain encoded passwords: KeystorePassword KeyPasswords TrustStorePassword

To encode a password again in one of the previous files, complete the following steps:

1. Access the file using a text editor and type over the encoded password.
   The new password is shown is no longer encoded and must be re-encoded.
2. Use the PropFilePasswordEncode script in the profile_root/bin/ directory to encode the password again.

   If you are encoding files that are not SAS properties files, type PropFilePasswordEncoder "file_name" password_properties_list

   "file_name" is the name of the SAS properties file and password_properties_list is the name of the properties to encode within the file.

   Note: Only the password should be encoded in this file by using the PropFilePasswordEncoder tool.

   Use the PropFilePasswordEncoder tool to encode WebSphere Application Server password files only. The utility cannot encode passwords that are contained in XML files or other files that contain open and close tags. To change passwords in these files, use the administrative console or an assembly tool such as the Rational® Application Developer.
