72.2. Enveloped Data

crypto-cms:encypt エンドポイントは、通常 1 つのルートで定義され、別のルートでは complimentary crypto-cms:decrypt で定義されます。ただし、これは他のエンドポイントの後に表示される例を簡単にするためです。

以下の例は、Enveloped Data メッセージを作成する方法と、Enveloped Data メッセージを復号化する方法を示しています。

Java DSL の基本例

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 の基本例

   <keyStoreParameters xmlns="http://camel.apache.org/schema/spring"

        password="some_password" type="JCEKS" />
    <bean id="recipient1"
