运行ASP.NET WebForms应用程序时从类库的代码中读取安全的.pem文件

Question

I have an ASP.NET Solution with a Webforms app and a class library. In the class library there is text that needs to read from a .pem file using

File.ReadAllText('PATH GOES HERE')

Currently the .pem file is sitting in the root directory of the class library. Is there any possible way to tell the code to access it from here? It seems like it keeps looking for it at:

C:\\Program Files (x86)\\IIS Express\\private_key.pem

Should I store this file somewhere else?

I need a secure place to store it where only the File.ReadAllText can access it and not anyone through the website.

Answer 1

In WinForm App, use

string fileName = "~/relative/path/to/privacy_key.pem";
string absolutePath = Server.MapPath(fileName);

Then in your Class Library, you can easily read the file using the absolute path.

You can also store the .pem path in Web.config , so that it's easy to configure in the future.
