SecretKeyFactory.getInstance（）引发单元测试中所有算法的异常 [英] SecretKeyFactory.getInstance() throws exception for all algorithms in unit tests

问题描述

由于某种原因，无论指定哪种算法，在调用SecretKeyFactory.getInstance（）时我总是在单元测试中遇到异常。例如：

  SecretKeyFactory.getInstance（ PBEWITHMD5ANDDES）
 
 com.mhe.connect.util .EncryptionException：java.security.NoSuchAlgorithmException：PBEWITHMD5ANDDES SecretKeyFactory不可用
  

同时，我看到Security.getProviders（）返回我所需的算法：

  SECRETKEYFACTORY.DESEDE SunJCE 
 SECRETKEYFACTORY.PBEWITHMD5ANDDES SunJCE 
 SECRETKEYFACTORY.DES SUNJCE 
 SECRETKEYFACTORY.PBEWITHMD5和三位一体的SunJCE 
 SECRETKEYFACTORY.PBKDF2WITHHMACSHA1 SunJCE 
 SECRETKEYFACTORY.PBEWITHSHA1ANDDESEDE SunJCE 
 $ PB $ b SEC_KEY1 p $ p> 
 
 
这仅在单元测试（来自Maven或IDE）中发生，并且如果代码在Jetty下运行（从同一Maven / JDK运行），效果很好。
 
 
 
这种行为的原因可能是什么？ 
解决方案
今天遇到同样的问题。通过在类中添加 @PowerMockIgnore（ javax.crypto。*）来解决。
 
 
 
有人知道吗是否可以全局忽略此软件包？我不想将其添加到执行该程序包中的代码的每个类中。
 
By some reason I always get exception in unit test when calling SecretKeyFactory.getInstance() no matter what algorithm is specified. For example:
SecretKeyFactory.getInstance("PBEWITHMD5ANDDES")

com.mhe.connect.util.EncryptionException: java.security.NoSuchAlgorithmException: PBEWITHMD5ANDDES SecretKeyFactory not available
At the same time, I see that Security.getProviders() returns me needed algorithms:
SECRETKEYFACTORY.DESEDE SunJCE
SECRETKEYFACTORY.PBEWITHMD5ANDDES SunJCE
SECRETKEYFACTORY.DES SunJCE
SECRETKEYFACTORY.PBEWITHMD5ANDTRIPLEDES SunJCE
SECRETKEYFACTORY.PBKDF2WITHHMACSHA1 SunJCE
SECRETKEYFACTORY.PBEWITHSHA1ANDDESEDE SunJCE
SECRETKEYFACTORY.PBEWITHSHA1ANDRC2_40 SunJCE
This happens only in unit tests (from Maven, or IDE) and works fine if code is running under Jetty (that is run from same Maven/JDK).

What could be the reason for such behavior? 
解决方案
Ran into the same issue today. Solved it by adding @PowerMockIgnore ("javax.crypto.*") to the class.

Does anyone know if I can globally ignore this package? I don't want to add it to every class that executes code from that package.
