通过

动态和静态地注册BC提供程序后，通过错误日志获取上述异常

Security.addProvider(new BouncyCastleProvider());

但是，

Cipher.getInstance("AES/CTS/NoPadding", "BC")

我收到以下错误

 Failure to decrypt: bad encryption: 
 java.lang.SecurityException: JCE cannot authenticate the provider BC

Answer 1

我相信任何JCE提供程序JAR必须先签名才能被Java运行时信任。看来你所拥有的jar中有无内容的内容。

如果这是您添加到jar或您制作的jar中的内容，请查看此答案，告诉您如何签名：How to sign a custom JCE security provider
