java - Jasypt:加密成功，但解密失败，因为算法更强

Question

我正在使用 Jasypt 的 CLI 来测试加密和解密。所有算法的加密都成功，但更强的算法解密失败。以下是PBEWithMD5AndDES的加密和解密:

现在，如果我将算法更改为 PBEWITHHMACSHA1ANDAES_128，结果如下:

Operation not possible (Bad input or parameters)

我使用的jasypt版本是2.0.0，我已经在java-8和java-11上尝试过这个版本。在两台机器中，我都启用了JCE 的无限强度策略。

解密成功的算法列表为:PBEWITHMD5ANDDES，PBEMD5 和三倍，PBEWITHSHA1和DESEDE，PBEWITHSHA1ANDRC2_128，PBEWITHSHA1ANDRC2_40，PBEWITHSHA1ANDRC4_128，PBEWITHSHA1ANDRC4_40。解密失败的算法有:PBEWITHHMACSHA1ANDAES_128
PBEWITHHMACSHA1ANDAES_256
PBEWITHHMACSHA224ANDAES_128PBEWITHHMACSHA224ANDAES_256PBEWITHHMACSHA256ANDAES_128PBEWITHHMACSHA256ANDAES_256PBEWITHHMACSHA384ANDAES_128PBEWITHHMACSHA384ANDAES_256PBEWITHHMACSHA512ANDAES_128PBEWITHHMACSHA512ANDAES_256。

我已经被这个问题困扰三天了。有人请帮帮我!

编辑:根据 Maarten 的建议，我继续从 JasyptPBEStringDecryptionCLI 复制代码并制作了自己的类，希望通过代码重现错误并获取堆栈跟踪。这是我写的代码:

package com.example.HelloWorldApiUbuntu;
import java.util.Properties;
import org.jasypt.intf.service.JasyptStatelessService;

public class TestingJasyptStringDecryptionCLI {
    public static void main(final String[] args) throws Exception{

        final JasyptStatelessService service = new JasyptStatelessService();
        String input = "P/25Hp3CKdFj7pz85eJyHETugwX5ZxWEF7PpzJ/fBGI=";

        final String result =
            service.decrypt(
                    input, 
                    "secret",
                    null,
                    null,
                    "PBEWITHHMACSHA512ANDAES_128",
                    null,
                    null,
                    "1000",
                    null,
                    null,
                    "org.jasypt.salt.RandomSaltGenerator",
                    null,
                    null,
                    "SunJCE",
                    null,
                    null,
                    /*argumentValues.getProperty(ArgumentNaming.ARG_PROVIDER_CLASS_NAME)*/null,
                    null,
                    null,
                    /*argumentValues.getProperty(ArgumentNaming.ARG_STRING_OUTPUT_TYPE)*/null,
                    null,
                    null);

        System.out.println(result);
    }
}

此类产生与 JasyptPBEStringDecryptionCLI 相同的行为，并且适用于上面列出的相同算法，但在更强的算法上失败。这是小错误堆栈跟踪:

Exception in thread "main" org.jasypt.exceptions.EncryptionOperationNotPossibleException
    at org.jasypt.encryption.pbe.StandardPBEByteEncryptor.decrypt(StandardPBEByteEncryptor.java:1055)
    at org.jasypt.encryption.pbe.StandardPBEStringEncryptor.decrypt(StandardPBEStringEncryptor.java:725)
    at org.jasypt.intf.service.JasyptStatelessService.decrypt(JasyptStatelessService.java:595)
    at com.example.HelloWorldApiUbuntu.TestingJasyptStringDecryptionCLI.main(TestingJasyptStringDecryptionCLI.java:12)

我知道问题出在 jasypt 而不是我的 java，因为我运行了 this code to test encryption-decryption在我的本地上，具有更强大的算法，并且效果完美。

编辑2:我也尝试了 https://github.com/melloware/jasypt 给出的解决方案，它给了我相同的结果。

Answer 1

它与 Jasypt 1.9.3 一起使用，带有附加参数 ivGeneratorClassName=org.jasypt.iv.RandomIvGenerator
