java - Jasypt 使用 Bouncy CaSTLe 的 EncryptionOperationNotPossibleException

Question

我尝试使用 Jasypt与 Bouncy Castle crypro 在 Spring 应用程序中提供(128 位 AES)来解密实体属性，同时使用 Hibernate 保存它们。但是当尝试保存实体时，我总是得到这个 org.jasypt.exceptions.EncryptionOperationNotPossibleException。

org.jasypt.exceptions.EncryptionOperationNotPossibleException
  Encryption raised an exception. A possible cause is you are using strong encryption
  algorithms and you have not installed the Java Cryptography Extension (JCE) Unlimited
  Strength Jurisdiction Policy Files in this Java Virtual Machine

(下面的完整堆栈跟踪)

我不使用 Java 加密扩展 (JCE)，这就是我尝试使用 Bouncy Castle 的原因

我认为 spring 配置有问题，有人发现问题了吗？

我的 Spring 配置是:

<bean id="bouncyCastleProvider" class="org.bouncycastle.jce.provider.BouncyCastleProvider"/>
<bean class="org.jasypt.hibernate4.encryptor.HibernatePBEStringEncryptor" depends-on="bouncyCastleProvider">

    <property name="provider" ref="bouncyCastleProvider"/>  
    <property name="providerName" value="BC"/>

    <property name="saltGenerator">
        <bean class="org.jasypt.salt.RandomSaltGenerator"/>
    </property>

    <property name="registeredName" value="STRING_ENCRYPTOR"/>      
    <property name="algorithm" value="PBEWITHSHA256AND128BITAES-CBC-BC"/>
    <property name="password" value="sEcRET1234"/>
</bean>

用法:

@Entity
@TypeDef(name = "encryptedString", typeClass = EncryptedStringType.class, parameters = { @Parameter(name = "encryptorRegisteredName", value = "STRING_ENCRYPTOR") })
public class SubscriptionProcess {
  ...      
   @Type(type = "encryptedString")
   private String debitAccountIban;
  ...
}

Answer 1

Jasypt旨在与 JCE 提供者 一起使用，该项目在其 Web 上使用的术语可能会使您感到困惑，因为有以下句子:

Open API for use with any JCE provider, and not only the default Java VM one. Jasypt can be easily used with well-known providers like Bouncy Castle

从这句话中，您可能了解到 Jasypt 可以与 JCE 或 BouncyCaSTLe 一起使用，就像两者的工作方式不同或类似的东西一样；然而，这句话的意思是有很多JCE providers，默认的java安装和非默认的提供者，但是都完成了JCA/JCE specification。两者都可以与 Jasypt 一起工作。

正如我所说，BouncyCaSTLe 有一个 JCE 提供者，来自 bouncycastle你可以看到:

A provider for the Java Cryptography Extension and the Java Cryptography Architecture.

因此，如果您尝试使用 org.bouncycaSTLe.jce.provider.BouncyCaSTLeProvider 作为提供者进行加密/解密操作，您将受到与所有 JCE 供应商有，尊重可用的算法和 key 长度。

要避免这种关于 key 长度和算法的限制并传递您遇到的错误，您必须为您的 jvm 版本安装 Java 加密扩展 (JCE) 无限强度管辖策略文件。

例如，对于 java 1.7，您可以从 here 下载文件.然后复制 $JAVA_HOME\jre\lib\security 中的 jar 覆盖现有的 local_policy.jar 和 US_export_policy.jar。

希望这对您有所帮助。
