75.3. Enveloped 数据

请注意，crypto-cms:encypt 端点通常在一个路由中定义，而在另一个路由中包括 complimentary crypto-cms:decrypt，但在另一个路由中简单来说是简单的。

以下示例演示了如何创建 Enveloped Data 消息以及如何解密 Enveloped Data 消息。

Java DSL 中的基本示例

import org.apache.camel.util.jsse.KeyStoreParameters;
import org.apache.camel.component.crypto.cms.crypt.DefaultKeyTransRecipientInfo;
...
KeyStoreParameters keystore  = new KeyStoreParameters();
keystore.setType("JCEKS");
keystore.setResource("keystore/keystore.jceks);
keystore.setPassword("some_password"); // this password will also be used for accessing the private key if not specified in the crypto-cms:decrypt endpoint

DefaultKeyTransRecipientInfo recipient1 = new DefaultKeyTransRecipientInfo();
recipient1.setCertificateAlias("rsa"); // alias of the public key used for the encryption
recipient1.setKeyStoreParameters(keystore);

simpleReg.put("keyStoreParameters", keystore); // register keystore in the registry
simpleReg.put("recipient1", recipient1); // register recipient info in the registry

from("direct:start")
    .to("crypto-cms:encrypt://testencrpyt?toBase64=true&recipient=#recipient1&contentEncryptionAlgorithm=DESede/CBC/PKCS5Padding&secretKeyLength=128")
    .to("crypto-cms:decrypt://testdecrypt?fromBase64=true&keyStoreParameters=#keyStoreParameters")
    .to("mock:result");

Spring XML 中的基本示例

   <keyStoreParameters xmlns="http://camel.apache.org/schema/spring"
        id="keyStoreParameters1" resource="./keystore/keystore.jceks"
        password="some_password" type="JCEKS" />
    <bean id="recipient1"
        class="org.apache.camel.component.crypto.cms.crypt.DefaultKeyTransRecipientInfo">
        <property name="keyStoreParameters" ref="keyStoreParameters1" />
        <property name="certificateAlias" value="rsa" />
    </bean>
...
    <route>
        <from uri="direct:start" />
        <to uri="crypto-cms:encrypt://testencrpyt?toBase64=true&amp;recipient=#recipient1&amp;contentEncryptionAlgorithm=DESede/CBC/PKCS5Padding&amp;secretKeyLength=128" />
        <to uri="crypto-cms:decrypt://testdecrypt?fromBase64=true&amp;keyStoreParameters=#keyStoreParameters1" />
         <to uri="mock:result" />
    </route>
