The default communication between execution servers and the application server uses a default security certificate. You can set up your own security configuration for the communication between execution servers and the application server by replacing the default keystores with your own. The keystores contain the security certificates and keys to enable secure SSL communication between execution servers and the application server. For security reasons, both the keystore and the key passwords must be encrypted. The SSL Password Encrypter tool enables you to encrypt a custom password. The Performance Manager application server and execution servers need to use this encrypted password so that the communication with the custom keystore can be enabled.
