我正在尝试使用jasypt加密和解密密码。我将代码编写为：

// Constructor
public Encrypt() {

    super();

    pooledPBEStringEncryptor = new PooledPBEStringEncryptor();

    pooledPBEStringEncryptor.setPassword(encryptionKey);
    pooledPBEStringEncryptor.setAlgorithm("PBEWITHHMACSHA512AND256BITAES");
    pooledPBEStringEncryptor.setPoolSize(4);
    pooledPBEStringEncryptor.setSaltGenerator(new RandomSaltGenerator());
}
``` `encryptionKey` 是静态字符串。要加密的代码是：

public static String encryptIt(String value) {

String encrypted = null;

// Encrypt & Encode
try {

    encrypted = pooledPBEStringEncryptor.encrypt(value);            

} catch (Exception e) {
    throw new RuntimeException("Security Error in doEncrypt: " + e);
}

return encrypted;

}

现在当我运行代码时。我得到一个错误：

一开始我得到的是 `EncryptionNotPossible` 例外。但我在google上搜索了一下，发现我需要把jcejars（本地和美国策略）放到jre的安全文件夹中。在这样做之后，我得到了这个错误。你能告诉我我做错了什么吗？如果jdk1.8有用的话，我正在使用它。
