Jasypt 和 Bouncy Castle 的 EncryptionOperationNotPossibleException
EncryptionOperationNotPossibleException by Jasypt with Bouncy Castle
我尝试使用 Jasypt with 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。但是我在尝试保存实体时总是得到这个 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

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;

Jasypt 旨在与 JCE providers 一起使用，该项目在其网站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，这句话的意思是有许多 JCE providers 默认提供程序，默认 java 安装和非默认提供程序，但是两者都完成 JCA/JCE specification 并且都可以与 Jasypt 一起工作.
正如我所说的BouncyCastle有一个JCE provider，从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 encrypt/decrypt 操作，您将受到与所有 JCE 提供者相同的限制，尊重可用算法和密钥长度。
要避免这种关于密钥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 Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files。
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 jars 覆盖现有的 local_policy.jar 和 US_export_policy.jar.
希望这对您有所帮助。
请检查 JRE 主目录 路径（右键单击 windows->首选项-> 单击位置 -> 检查 JRE 主目录路径是否指向jdk）如果它指向jre请将其更改为jdk.
