Libsodium-net - 无法加载 DLL 'libsodium.dll

Question

我通过 NuGet 安装了 Libsodium-net 并且能够在我的类中包含 Sodium，但是当我尝试运行它时，我得到

'System.DllNotFoundException' 类型的异常发生在 Sodium.dll 中，但未在用户代码中处理

附加信息：无法加载 DLL 'libsodium.dll'：找不到指定的模块。（HRESULT 异常：0x8007007E）

我只是想运行 gitbooks 文档中的示例代码 https://bitbeans.gitbooks.io/libsodium-net/content/password_hashing/index.html

const string PASSWORD = "Correct Horse Battery Staple";
const string SALT = "qa~t](84z<1t<1oz:ik.@IRNyhG=8q(o";
const long OUTPUT_LENGTH = 512;

//this will produce a 512 byte hash
var hash = PasswordHash.ScryptHashBinary(PASSWORD, SALT,      PasswordHash.Strength.Medium, OUTPUT_LENGTH);

Answer 1

我遇到了同样的问题并使用解决了它。

It turns out that ASP.NET doesn't make shadow copies of unmanaged DLLs such as libsodium.dll and libsodium-64.dll.

Sodium.dll (the managed code) tries to load the DLLs from either the same directory as the shadow copy of Sodium.dll (which is not going to work) - or some where in the PATH environment variable's directories.

My solution was to add the AppDomain \Bin directory to the path before calling any Sodium code:
string path = Environment.GetEnvironmentVariable("PATH");
string binDir = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Bin");
Environment.SetEnvironmentVariable("PATH", path + ";" + binDir);

正如鲁本对答案的评论；我在 Global.asax.

的 Application_Start 方法中添加了上面的代码

我也收到了这个。解决方案的第一部分是像@NiklasEkman 那样做，将目录添加到 PATH 变量。

但是，当部署到我们的 QA 环境时，我遇到了完全相同的错误。在花了几个小时弄乱权限后，试图弄清楚 dll 是否在正确的目录中，类似的我运行进入这个 post： https://mspcontrol.org/forums/topic/add-user-error-unable-to-load-dll-libsodium-64-dll/#post-4765

You have to install Visual C++ Redistributable for Visual Studio 2015 (13 Mb) https://www.microsoft.com/en-us/download/details.aspx?id=48145

最终为我解决了这个问题。
