Method Detail

builder

public static SecurityConfig.Builder builder()

Creates a builder to customize the SecurityConfig configuration.

Returns:

the builder to customize.

create

public static SecurityConfig create()

Creates a SecurityConfig with the default configuration.

Returns:

the default security config.

enableTls

public static SecurityConfig.Builder enableTls(boolean tlsEnabled)

Enables TLS for all client/server communication (disabled by default).

Parameters:

tlsEnabled - true if enabled, false otherwise.

Returns:

this SecurityConfig.Builder for chaining purposes.

enableHostnameVerification

public static SecurityConfig.Builder enableHostnameVerification(boolean hostnameVerificationEnabled)

Allows to enable or disable hostname verification (enabled by default).

Note that disabling hostname verification will cause the TLS connection to not verify that the hostname/ip is actually part of the certificate and as a result not detect certain kinds of attacks. Only disable if you understand the impact and risks!

Parameters:

hostnameVerificationEnabled - set to true if it should be enabled, false for disabled.

Returns:

this SecurityConfig.Builder for chaining purposes.

enableNativeTls

public static SecurityConfig.Builder enableNativeTls(boolean nativeTlsEnabled)

Enables/disables native TLS (enabled by default).

Parameters:

nativeTlsEnabled - true if it should be enabled, false otherwise.

Returns:

this SecurityConfig.Builder for chaining purposes.

trustCertificates

public static SecurityConfig.Builder trustCertificates(List<X509Certificate> certificates)

Loads the given list of X.509 certificates into the trust store.

Parameters:

certificates - the list of certificates to load.

Returns:

this SecurityConfig.Builder for chaining purposes.

trustCertificate

public static SecurityConfig.Builder trustCertificate(Path certificatePath)

Loads a X.509 trust certificate from the given path and uses it.

Parameters:

certificatePath - the path to load the certificate from.

Returns:

this SecurityConfig.Builder for chaining purposes.

trustStore

public static SecurityConfig.Builder trustStore(KeyStore trustStore)

Initializes the TrustManagerFactory with the given trust store.

Parameters:

trustStore - the loaded trust store to use.

Returns:

this SecurityConfig.Builder for chaining purposes.

trustStore

public static SecurityConfig.Builder trustStore(Path trustStorePath,
                                                String trustStorePassword,
                                                Optional<String> trustStoreType)

Loads a trust store from a file path and password and initializes the TrustManagerFactory.

Parameters:

trustStorePath - the path to the truststore.

trustStorePassword - the password (can be null if not password protected).

trustStoreType - the type of the trust store. If empty, the KeyStore.getDefaultType() will be used.

Returns:

this SecurityConfig.Builder for chaining purposes.

trustManagerFactory

public static SecurityConfig.Builder trustManagerFactory(TrustManagerFactory trustManagerFactory)

Allows to provide a trust manager factory directly for maximum flexibility.

While providing the most flexibility, most users will find the other overloads more convenient, like passing in a trustStore(KeyStore) directly or via filepath trustStore(Path, String, Optional).

Parameters:

trustManagerFactory - the trust manager factory to use.

Returns:

this SecurityConfig.Builder for chaining purposes.

ciphers

public static SecurityConfig.Builder ciphers(List<String> ciphers)

Allows to customize the list of ciphers that is negotiated with the cluster.

Note that this method is considered advanced API, please only customize the cipher list if you know what you are doing (for example if you want to shrink the cipher list down to a very specific subset for security or compliance reasons).

If no custom ciphers are configured, the default set will be used.

Parameters:

ciphers - the custom list of ciphers to use.

Returns:

this SecurityConfig.Builder for chaining purposes.

tlsEnabled

public boolean tlsEnabled()

True if TLS is enabled, false otherwise.

Returns:

a boolean if tls/transport encryption is enabled.

hostnameVerificationEnabled

public boolean hostnameVerificationEnabled()

True if TLS hostname verification is enabled, false otherwise.

trustCertificates

public List<X509Certificate> trustCertificates()

The list of trust certificates that should be used, if present.

Returns:

the list of certificates.

trustManagerFactory

public TrustManagerFactory trustManagerFactory()

The currently configured trust manager factory, if present.

Returns:

the trust manager factory.

nativeTlsEnabled

public boolean nativeTlsEnabled()

Returns whether native TLS is enabled.

Returns:

true if enabled, false otherwise.

ciphers

public List<String> ciphers()

Returns the custom list of ciphers.

Returns:

the custom list of ciphers.

decodeCertificates

public static List<X509Certificate> decodeCertificates(List<String> certificates)

Helper method to decode string-encoded certificates into their x.509 format.

Parameters:

certificates - the string-encoded certificates.

Returns:

the decoded certs in x.509 format.

defaultCiphers

public static List<String> defaultCiphers(boolean nativeTlsEnabled)

Lists the default ciphers used for this platform.

Note that the list of ciphers can differ whether native TLS is enabled or not, so the parameter should reflect the actual security configuration used. Native TLS is enabled by default on the configuration, so if it is not overridden it should be set to true here as well.

Parameters:

nativeTlsEnabled - if native TLS is enabled on the security configuration (defaults to yes there).

Returns:

the list of default ciphers.
