=== SSL certificate API
|
|
++++
|
|
<titleabbrev>SSL certificate</titleabbrev>
|
|
++++
|
|
|
|
The `certificates` API enables you to retrieve information about the X.509
|
|
certificates that are used to encrypt communications in your {es} cluster.
|
|
|
|
==== Request
|
|
|
|
`GET /_ssl/certificates`
|
|
|
|
|
|
==== Description
|
|
|
|
For more information about how certificates are configured in conjunction with
|
|
Transport Layer Security (TLS), see
|
|
{stack-ov}/ssl-tls.html[Setting up SSL/TLS on a cluster].
|
|
|
|
The API returns a list that includes certificates from all TLS contexts
|
|
including:
|
|
|
|
* Settings for transport and HTTP interfaces
|
|
* TLS settings that are used within authentication realms
|
|
* TLS settings for remote monitoring exporters
|
|
|
|
The list includes certificates that are used for configuring trust, such as
|
|
those configured in the `xpack.security.transport.ssl.truststore` and
|
|
`xpack.security.transport.ssl.certificate_authorities` settings. It also
|
|
includes certificates that are used for configuring server identity, such as
|
|
`xpack.security.http.ssl.keystore` and
|
|
`xpack.security.http.ssl.certificate` settings.
|
|
|
|
The list does not include certificates that are sourced from the default SSL
|
|
context of the Java Runtime Environment (JRE), even if those certificates are in
|
|
use within {es}.
|
|
|
|
NOTE: When a PKCS#11 token is configured as the truststore of the JRE, the API
|
|
will return all the certificates that are included in the PKCS#11 token
|
|
irrespectively to whether these are used in the {es} TLS configuration or not.
|
|
|
|
If {es} is configured to use a keystore or truststore, the API output
|
|
includes all certificates in that store, even though some of the certificates
|
|
might not be in active use within the cluster.
|
|
|
|
|
|
==== Results
|
|
|
|
The response is an array of objects, with each object representing a
|
|
single certificate. The fields in each object are:
|
|
|
|
`path`:: (string) The path to the certificate, as configured in the
|
|
`elasticsearch.yml` file.
|
|
`format`:: (string) The format of the file. One of: `jks`, `PKCS12`, `PEM`.
|
|
`alias`:: (string) If the path refers to a container file (a jks keystore, or a
|
|
PKCS#12 file), the alias of the certificate. Otherwise, null.
|
|
`subject_dn`:: (string) The Distinguished Name of the certificate's subject.
|
|
`serial_number`:: (string) The hexadecimal representation of the certificate's
|
|
serial number.
|
|
`has_private_key`:: (boolean) If {es} has access to the private key for this
|
|
certificate, this field has a value of `true`.
|
|
`expiry`:: (string) The ISO formatted date of the certificate's expiry
|
|
(not-after) date.
|
|
|
|
==== Authorization
|
|
|
|
If the {security-features} are enabled, you must have `monitor` cluster
|
|
privileges to use this API. For more information, see
|
|
{stack-ov}/security-privileges.html[Security Privileges].
|
|
|
|
|
|
==== Examples
|
|
|
|
The following example provides information about the certificates on a single
|
|
node of {es}:
