c# - 将 SSL dll 导入项目

Question

我有一个从旧系统导入的项目。 这段代码成为最有问题的

PacketGroup = new ArrayList();
Crypto = new GameCrypto(ASCIIEncoding.ASCII.GetBytes(STRING_CRYPTO));
KeyExchance = new OpenSSL.Crypto.DH();
KeyExchance.G = RANDOM_INT;
KeyExchance.P = OpenSSL.Core.BigNumber.FromHexString("KEY__KEY_KEY\0");
KeyExchance.GenerateKeys();
NewServerIV = GenerateIV();
NewClientIV = GenerateIV();

起初我收到错误:

System.TypeInitializationException: The type initializer for 'OpenSSL.Native' th rew an exception. ---> System.Exception: Invalid version of libeay32.dll, expect ing 0.9.8a Development, got: 1.0.0 Release

我在项目中导入了最新的SSL库，出现了这个错误(在Crypto = new GameCrypto()这一行)

System.DllNotFoundException: Unable to load DLL 'libeay32.dll': The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail. (Exception from HRESULT: 0x800736B1)

我能够解决这个问题，但我被困在这个问题上(在 new OpenSSL.Crypto.DH() 线上)

System.TypeInitializationException: The type initializer for 'OpenSSL.Core.Native' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'ssleay32': The operating system cannot run . (Exception from HRESULT: 0x800700B6)

Answer 1

您的应用程序目录中需要一份 libeay32.dll、libssl32.dll 和 ssleay32.dll

1. 将非托管 dll 作为文件或链接文件添加到您的项目中。 (右键单击项目 -> 添加 -> 现有文件，然后添加或添加为链接)。

2. 在解决方案资源管理器中选择文件。在属性窗口中将构建操作设置为始终复制。

Don't forget that the unmanaged DLL could itself require other unmanaged DLL's. If you forget to add those as well, you could get the exact same error. You can use dependency walker to help you if you are not sure what the dependencies are.
