# Defining an SSL connection to other applications

To configure secured connection (SSL/TLS) to other applications in Talend Administration Center, you need to specify the keystore.path, keystore.password, truststore.path, truststore.password properties in the configuration.properties file.

If you used secured connection in previous versions and these properties were not specified before, then import correct certificate to keystore and truststore and specify the keystore.path, keystore.password, truststore.path, truststore.password properties in the configuration.properties file.

## Procedure

1. Stop your Tomcat server.
2. Open the following file:

   <ApplicationPath>/WEB-INF/classes/configuration.properties
3. Uncomment and edit the following lines to define your keystore path, keystore password, truststore path, and truststore password:
   ```
   #keystore.path=c://keystore
   #keystore.password=changekeystorepass
   #truststore.path=c://truststore
   #truststore.password=changetruststorepass
   ```
4. Save your changes and restart your Tomcat server.

   Once the passwords are read by Talend Administration Center, they will be replaced by encrypted ones.
