tag::ssl-key-pem[]
Path to a PEM encoded file containing the private key.
//TBD: You cannot use this setting and `ssl.keystore.path` at the same time.
end::ssl-key-pem[]
tag::ssl-key-passphrase[]
The passphrase that is used to decrypt the private key. Since the key might not
be encrypted, this value is optional.
//TBD: You cannot use this setting and `ssl.secure_key_passphrase` at the same time.
end::ssl-key-passphrase[]
tag::ssl-keystore-key-password[]
The password for the key in the keystore. The default is the keystore password.
//TBD: You cannot use this setting and `ssl.keystore.secure_key_password` at the same time.
end::ssl-keystore-key-password[]
tag::ssl-keystore-password[]
The password for the keystore.
//TBD: You cannot use this setting and `ssl.keystore.secure_password` at the same time.
end::ssl-keystore-password[]
tag::ssl-keystore-path[]
The path for the keystore file that contains a private key and certificate.
//TBD: It must be either a Java keystore (jks) or a PKCS#12 file.
//TBD: You cannot use this setting and `ssl.key` at the same time.
end::ssl-keystore-path[]
tag::ssl-keystore-secure-key-password[]
The password for the key in the keystore. The default is the keystore password.

end::ssl-keystore-secure-password[]
tag::ssl-keystore-type-pkcs12[]
The format of the keystore file. It must be either `jks` or `PKCS12`. If the
keystore path ends in ".p12", ".pfx", or ".pkcs12", this setting defaults
to `PKCS12`. Otherwise, it defaults to `jks`.
end::ssl-keystore-type-pkcs12[]
tag::ssl-secure-key-passphrase[]
The passphrase that is used to decrypt the private key. Since the key might not
be encrypted, this value is optional.
//TBD: You cannot use this setting and `ssl.key_passphrase` at the same time.

tag::ssl-supported-protocols[]
Supported protocols with versions. Valid protocols: `SSLv2Hello`,
`SSLv3`, `TLSv1`, `TLSv1.1`, `TLSv1.2`, `TLSv1.3`. If the JVM's SSL provider supports TLSv1.3,
the default is `TLSv1.3,TLSv1.2,TLSv1.1`. Otherwise, the default is
`TLSv1.2,TLSv1.1`.

NOTE: If `xpack.security.fips_mode.enabled` is `true`, you cannot use `SSLv2Hello`
or `SSLv3`. See <<fips-140-compliance>>.

tag::ssl-truststore-password[]
The password for the truststore.
//TBD: You cannot use this setting and `ssl.truststore.secure_password` at the same time.
end::ssl-truststore-password[]
tag::ssl-truststore-path[]
The path for the keystore that contains the certificates to trust. It must be
either a Java keystore (jks) or a PKCS#12 file.
//TBD: You cannot use this setting and `ssl.certificate_authorities` at the same time.

Password for the truststore.
//TBD: You cannot use this setting and `ssl.truststore.password` at the same time.
end::ssl-truststore-secure-password[]
tag::ssl-truststore-type[]
The format of the truststore file. It must be either `jks` or `PKCS12`. If the
file name ends in ".p12", ".pfx" or "pkcs12", the default is `PKCS12`.
Otherwise, it defaults to `jks`.
end::ssl-truststore-type[]
tag::ssl-truststore-type-pkcs11[]
The format of the truststore file. For the Java keystore format, use `jks`. For
PKCS#12 files, use `PKCS12`. For a PKCS#11 token, use `PKCS11`. The default is
`jks`.
end::ssl-truststore-type-pkcs11[]
tag::ssl-verification-mode-values[]
Valid values are:
- `full`, which verifies that the provided certificate is signed by a trusted
authority (CA) and also verifies that the server's hostname (or IP address)
matches the names identified within the certificate.
- `certificate`, which verifies that the provided certificate is signed by a
trusted authority (CA), but does not perform any hostname verification.
- `none`, which performs _no verification_ of the server's certificate. This
mode disables many of the security benefits of SSL/TLS and should only be used
after very careful consideration. It is primarily intended as a temporary
diagnostic mechanism when attempting to resolve TLS errors; its use on
production clusters is strongly discouraged.

The default value is `full`.
