elasticsearch-syskeygen

elasticsearch-syskeygen [options]

elasticsearch-syskeygen creates a system_key file in the Elasticsearch configuration directory. This key is used to symmetrically encrypt sensitive data, such as preventing Watcher from returning and storing information that contains clear text credentials.

This tool is part of X-Pack. The generated system key must be the same across all nodes in a cluster. Use elasticsearch-keystore for managing secure settings in newer versions.
