Minimum Required Role: Configurator (also provided by Cluster Administrator, Full Administrator)
  1. Go to the KMS service.
  2. Click Configuration.
  3. In the Search field, type TLS/SSL to show the KMS TLS/SSL properties (in the Key Management Server Default Group > Security category).
  4. Edit the following TLS/SSL properties according to your cluster configuration.
    Property Description
    Enable TLS/SSL for Key Management Server Encrypt communication between clients and Key Management Server using Transport Layer Security (TLS) (formerly known as Secure Socket Layer (TLS/SSL)).
    Key Management Server TLS/SSL Server JKS Keystore File Location The path to the TLS/SSL keystore file containing the server certificate and private key used for TLS/SSL. Used when Key Management Server is acting as a TLS/SSL server. The keystore must be in JKS format.
    Key Management Server TLS/SSL Server JKS Keystore File Password The password for the Key Management Server JKS keystore file.
    Key Management Server Proxy TLS/SSL Certificate Trust Store File The location on disk of the truststore, in .jks format, used to confirm the authenticity of TLS/SSL servers that Key Management Server Proxy might connect to. This is used when Key Management Server Proxy is the client in a TLS/SSL connection. This truststore must contain the certificates used to sign the services connected to. If this parameter is not provided, the default list of well-known certificate authorities is used instead.
    Key Management Server Proxy TLS/SSL Certificate Trust Store Password The password for the Key Management Server Proxy TLS/SSL Certificate Trust Store File. This password is not required to access the truststore; this field can be left blank. This password provides optional integrity checking of the file. The contents of truststores are certificates, and certificates are public information.
