The out-of-the-box Sync Service provides keystore (sync.jks) and truststore (sync.truststore). The password for the keystore and truststore for the default installation is specified in the applicationConnectors section of the config.yml file:
server:
applicationConnectors:
keyStorePassword:
The keystore contains a private key and a self-signed certificate for the Sync Service. The truststore contains the self-signed certificate exported from the keystore to create a trust relationship between the Sync Service and itself. In production systems, the truststore usually contains only certificates that are trusted and signed by certificate authorities (CA).
Note: For production systems, it’s strongly advised that you use
your own SSL key and a certificate that’s signed by a certificate authority.
