@Tags({"ssl","secure","certificate","keystore","truststore","jks","p12","pkcs12","pkcs","tls"})
@CapabilityDescription("Standard implementation of the SSLContextService. Provides the ability to configure keystore and/or truststore properties once and reuse that configuration throughout the application. This service can be used to communicate with both legacy and modern systems. If you only need to communicate with non-legacy systems, then the StandardRestrictedSSLContextService is recommended as it only allows a specific set of SSL protocols to be chosen.")

Method Details

onConfigured

@OnEnabled
public void onConfigured(ConfigurationContext context)
                  throws InitializationException

Throws:

InitializationException

onPropertyModified

public void onPropertyModified(PropertyDescriptor descriptor,
 String oldValue,
 String newValue)

Specified by:

onPropertyModified in interface ConfigurableComponent

Overrides:

onPropertyModified in class AbstractConfigurableComponent

getSupportedPropertyDescriptors

protected List<PropertyDescriptor> getSupportedPropertyDescriptors()

Overrides:

getSupportedPropertyDescriptors in class AbstractConfigurableComponent

customValidate

protected Collection<ValidationResult> customValidate(ValidationContext validationContext)

Overrides:

customValidate in class AbstractConfigurableComponent

evaluateProperties

private Map<PropertyDescriptor,String> evaluateProperties(PropertyContext context)

resetValidationCache

private void resetValidationCache()

getValidationCacheExpiration

protected int getValidationCacheExpiration()

createTlsConfiguration

public TlsConfiguration createTlsConfiguration()

Returns a TlsConfiguration configured with the current properties of the controller service. This is useful for transferring the TLS configuration values between services.

Specified by:

createTlsConfiguration in interface SSLContextService

Returns:

the populated TlsConfiguration

createContext

public SSLContext createContext()

Create and initialize SSLContext using configured properties. This method is preferred over deprecated methods due to not requiring a client authentication policy. Invokes createTlsConfiguration() to prepare properties for processing.

Specified by:

createContext in interface SSLContextService

Returns:

SSLContext initialized using configured properties

createTrustManager

public X509TrustManager createTrustManager()

Create X.509 Trust Manager using configured properties
