我正在使用Jasypt的CLI来测试加密和解密。加密对于所有算法都是成功的,但解密对于更强大的算法是失败的。这是 PBEWithMD5AndDES 的加密和解密:
加密:

encryptThis
现在,如果将算法更改为 PBEWITHHMACSHA1ANDAES_128 ,则结果如下:

我使用的 jasypt 版本是 2.0.0 ,我已经在java-8和java-11上都尝试过。在两台机器中,我都启用了 JCE的无限强度策略。
成功解密的算法列表为:
PBEWITHMD5ANDDES,
PBEWITHMD5ANDTRIPLEDES,
PBEWITHSHA1ANDDESEDE,
PBEWITHSHA1ANDRC2_128,
PBEWITHSHA1ANDRC2_40,
PBEWITHSHA1ANDRC4_128,
PBEWITHSHA1ANDRC4_40。
解密失败的算法是:
PBEWITHHMACSHA1ANDAES_128
PBEWITHHMACSHA1ANDAES_256
PBEWITHHMACSHA224ANDAES_128
PBEWITHHMACSHA224ANDAES_256
PBEWITHHMACSHA256ANDAES_128
PBEWITHHMACSHA256ANDAES_256
PBEWITHHMACSHA384ANDAES_128
PBEWITHHMACSHA384ANDAES_256
PBEWITHHMACSHA512ANDAES_128
PBEWITHHMACSHA512ANDAES_256。
我被这个问题困扰了三天。有人请帮帮我!
编辑:
在收到Maarten的建议后,我继续进行操作,并从 JasyptPBEStringDecryptionCLI 复制了代码,并创建了自己的类,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stacktrace:
Exception in thread "main" org.jasypt.exceptions.EncryptionOperationNotPossibleException
at org.jasypt.encryption.pbe.StandardPBEByteEncryptor.decrypt(StandardPBEByteEncryptor.java:1055)

at com.example.HelloWorldApiUbuntu.TestingJasyptStringDecryptionCLI.main(TestingJasyptStringDecryptionCLI.java:12)
我知道问题出在 jasypt 而不是我的Java,因为我在本地使用更强大的算法运行this code to test encryption-decryption,并且效果很好。
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。
最佳答案
它可以与Jasypt 1.9.3一起使用,并带有附加参数ivGeneratorClassName = org.jasypt.iv.RandomIvGenerator
