JSSE Utility

The JSSE Utility, available as of 2.8, allows you to easily configure aspects of the Java Secure Socket Extension (JSSE) API in order to greatly simplify the use of custom transport layer security (TLS) settings on Camel components.

Supported Components

The following Camel components directly support the use of this configuration utility:

HTTP4
Jetty

The following Camel components indirectly support the use of this configuration utility:

CXF
HTTP

Configuration

The key component in configuring TLS through the JSSE API is the SSLContext. The SSLContext provides socket factories for both client-side and server-side sockets as well as another component called an SSLEngine that is used by non-blocking IO to support TLS. The JSSE configuration utility provides an easy to use builder for configuring these JSSE components, among others, in a manner that allows you to provide all configuration options up front during the initialization of your application such that you don't have to customize library code or dig though the inner workings of a third-party library in order to inject hooks for the configuration of each component in the JSSE API. The central builder in the JSSE configuration utility is the SSLContextParameters. This class serves as the entry point for most configuration in the JSSE utility.

All non-native classes are in the org.apache.camel.util.jsse package. All non-W3C schema defined types are in the http://camel.apache.org/schema/spring or http://camel.apache.org/schema/blueprint namespaces for Spring and Blueprint based configuration, respectively.

SSLContextParameters

Java Field Name and Class	XML Attribute/Element and Type	Description
cipherSuites - CipherSuitesParameters	sslContextParameters/ciphersuites - CipherSuitesParameters	This optional property represents a collection of explicitly named cipher suites to enable on both the client and server side as well as in the SSLEngine. These values take precedence over filters supplied in cipherSuitesFilter. The utility attempts to enable the listed cipher suites regardless of whether or not the JSSE provider actually supports them or not. This behavior guarantees that listed cipher suites are always enabled when listed. For a more lenient option, use cipherSuitesFilter.
cipherSuitesFilter - FilterParameters	sslContextParameters/cipherSuitesFilter - FilterParameters	This optional property represents a collection of include and exclude patterns for cipher suites to enable on both the client and server side as well as in the SSLEngine. The patterns are applied over only the available cipher suites. The exclude patterns have precedence over the include patterns. If no cipherSuites and no cipherSuitesFilter are present, the default patterns applied are: Includes .* Excludes .*NULL.* .*anon.*
secureSocketProtocols - SecureSocketProtocolsParameters	sslContextParameters/secureSocketProtocols - SecureSocketProtocolsParameters	This optional property represents a collection of explicitly named secure socket protocols, such as SSLv3/TLS/etc., to enable on both the client and server side as well as in the SSLEngine. These values take precedence over filters supplied in secureSocketProtocolsFilter. The utility attempts to enable the listed protocols regardless of whether or not the JSSE provider actually supports them or not. This behavior guarantees that listed protocols aree always enabled when listed. For a more lenient option, use secureSocketProtocolsFilter.
secureSocketProtocolsFilter - FilterParameters	sslContextParameters/secureSocketProtocolsFilter - FilterParameters	This optional property represents a collection of include and exclude patterns for secure socket protocols to enable on both the client and server side as well as in the SSLEngine. The patterns are applied over only the available protocols. The exclude patterns have precedence over the include patterns.

If omitted, no source of key material is provided and the SSLContext is suitable only for client-side usage when mutual authentication is not in use. You typically configure this property with a key store containing a client or server private key.
trustManagers - TrustManagersParameters	sslContextParameters/trustManagers - TrustManagersParameters	This optional property configures the source of material for verifying trust of key material used in the handshake process. If omitted, the default trust manager is automatically used. See the JSSE documentation for more information on how the default trust manager is configured. You typically configure this property with a key store containing trusted CA certificates.
secureRandom - SecureRandomParameters	sslContextParameters/secureRandom - SecureRandomParameters	This optional property configures the secure random number generator used by the client and server side as well as in the SSLEngine. If omitted, the default secure random number generator is used.
clientParameters - SSLContextClientParameters	sslContextParameters/clientParameters - SSLContextClientParameters	This optional property configures additional settings that apply only to the client side aspects of the SSLContext. If present, these settings override the settings specified at the SSLContextParameters level.
serverParameters - SSLContextServerParameters	sslContextParameters/serverParameters - SSLContextServerParameters	This optional property configures additional settings that apply only to the server side aspects of the SSLContext. If present, these settings override the settings specified at the SSLContextParameters level.

Examples

Programmatic Usage

Setting Client Authentication On the Server Side

This configuration sets the server side aspects of the TLS configuration to require client authentication during the handshake process. This configuration uses the default trust store and a custom key store to provide key material for both the server and client sides of the SSLContext.

KeyStoreParameters ksp = new KeyStoreParameters();
ksp.setResource("/users/home/server/keystore.jks");
ksp.setPassword("keystorePassword");


KeyManagersParameters kmp = new KeyManagersParameters();
kmp.setKeyStore(ksp);
kmp.setKeyPassword("keyPassword");

SSLContextServerParameters scsp = new SSLContextServerParameters();
scsp.setClientAuthentication(ClientAuthentication.REQUIRE);
SSLContextParameters scp = new SSLContextParameters();
scp.setServerParameters(scsp);
scp.setKeyManagers(kmp);

SSLContext context = scp.createSSLContext();
SSLEngine engine = scp.createSSLEngine();

Configuring Different Options on the Client and Server Side

KeyStoreParameters ksp = new KeyStoreParameters();
ksp.setResource("/users/home/server/keystore.jks");
ksp.setPassword("keystorePassword");

KeyManagersParameters kmp = new KeyManagersParameters();
kmp.setKeyStore(ksp);
kmp.setKeyPassword("keyPassword");

FilterParameters filter = new FilterParameters();
filter.getInclude().add(".*");

SSLContextClientParameters sccp = new SSLContextClientParameters();
sccp.setCipherSuitesFilter(filter);

SSLContextParameters scp = new SSLContextParameters();
scp.setClientParameters(sccp);
scp.setKeyManagers(kmp);

SSLContext context = scp.createSSLContext();
SSLEngine engine = scp.createSSLEngine();

Using Camel Property Placeholders

This configuration utility fully supports the use of property placeholders (see Using PropertyPlaceholder) in all configuration fields. In order to support this feature, the configuration utility objects must be configured with a reference to a Camel context. All of the utility classes except for CipherSuitesParameters and SecureSocketProtocolsParameters provide a setter method for providing the context reference. Do not confuse the lack of a setter on CipherSuitesParameters and SecureSocketProtocolsParameters as an indication that you cannot use property placeholders when configuring these classes. The lack of a setter is an internal implementation detail and full placeholder support is available for both of the configuration classes.

In this example, both the client and server sides share the same custom key store; however, the client side allows any supported cipher suite while the server side will use the default cipher suite filter and exclude any cipher suites that match the patterns .*NULL.* and .*anon.*.KeyStoreParameters ksp = new KeyStoreParameters();
ksp.setResource("/users/home/server/keystore.jks");
ksp.setPassword("keystorePassword");

KeyManagersParameters kmp = new KeyManagersParameters();
kmp.setKeyStore(ksp);
kmp.setKeyPassword("keyPassword");

FilterParameters filter = new FilterParameters();
filter.getInclude().add(".*");

SSLContextClientParameters sccp = new SSLContextClientParameters();
sccp.setCipherSuitesFilter(filter);

SSLContextParameters scp = new SSLContextParameters();
scp.setClientParameters(sccp);
scp.setKeyManagers(kmp);

SSLContext context = scp.createSSLContext();
SSLEngine engine = scp.createSSLEngine();
