A keystore file contains the keys and certificates required if you enable secure communication and use the HTTPS protocol for the Analyst Service.
You can create the keystore file when you install the Informatica services or you can create a keystore file with keytool. keytool is a utility that generates and stores private or public key pairs and associated certificates in a file called a “keystore.” When you generate a public or private key pair, keytool wraps the public key into a self-signed certificate. You can use the self-signed certificate or use a certificate signed by a certificate authority.
You must use a certified keystore file. If you do not use a certified keystore file, security warnings and error messages for the browser appear when you access the Analyst tool.
