tls
TLS configuration for securing leaf node connections.
Properties
| Name | Description | Type | Default | Reloadable |
|---|---|---|---|---|
allow_insecure_cipher_suites | Permit cipher suites Go considers insecure to be named in cipher_suites. Without it those names are rejected. | boolean | false | Yes |
cert_store | Load the certificate from an OS certificate store rather than a file. Windows only. | string | - | Yes |
certs | Multiple certificate/key pairs to serve, so one listener can present different certificates to different clients. Use this instead of cert_file and key_file. | object | - | Yes |
handshake_first | Force the leafnode connection to use a TLS-first handshake prior to the remote sending the INFO protocol message. Note, this option must be set to true on both the remote server accepting the leafnode connections as well as the leafnode itself. | boolean | false | Yes* |
min_version | Lowest TLS version the server will negotiate. | string | - | Yes |
ocsp_peer | Verify the peer's certificate against its OCSP responder and reject revoked certificates. Set an object to tune the checks. | (multiple) | false | Yes |
cert_file | TLS certificate file. | string | - | Yes* |
key_file | TLS certificate key file. | string | - | Yes* |
ca_file | TLS certificate authority file. Defaults to system trust store. | string | - | Yes* |
cipher_suites | When set, only the specified TLS cipher suites will be allowed. Values must match the golang version used to build the server. | string | - | Yes* |
curve_preferences | List of TLS cipher curves to use in order. | string | - | Yes* |
insecure | Skip certificate verification. This only applies to outgoing connections, NOT incoming client connections. not recommended. | boolean | - | Yes* |
timeout | TLS handshake timeout. | duration | 500ms | No |
verify | If true, require and verify client certificates. Does not apply to monitoring. | boolean | false | Yes* |
verify_and_map | If true, require and verify client certificates and map certificate values for authentication. Does not apply to monitoring. | boolean | false | No |
connection_rate_limit | integer | - | Ignored* | |
pinned_certs | List of hex-encoded SHA256 of DER-encoded public key fingerprints. When present, during the TLS handshake, the provided certificate's fingerprint is required to be present in the list, otherwise the connection will be closed. | string | - | No |
