SEC0027: Visual Studio 2015 Build Error

RE: Hkim

We were evaluating Puma.Security.Rules 1.0.6 against our old project and we are experiencing weird behavior. When you build, it says “build has started…” and just stays there… I was able to reconstruct this behavior and have created a console app to demonstrate this. Below is the snippet of code where this occurs.

I was expecting to see SEC0027 and SEC0029 warning messages but instead, it hangs during build and never finishes. Do you have any suggestions?

class Program
  {
    enum enuHashMethod : int
    {
      MD5 = 0,
      SHA1 = 1,
      SHA256 = 2,
      SHA384 = 3,
      SHA512 = 4
    }

    static void Main(string[] args)
    {
    }

    private static HashAlgorithm Algorithm(enuHashMethod hashMethod)
    {
      HashAlgorithm hashAlg = null;

      switch (hashMethod)
      {
        case enuHashMethod.MD5:
          hashAlg = new MD5CryptoServiceProvider();  // Build hangs… commenting out builds fine…
          break;
        case enuHashMethod.SHA1:
          hashAlg = new SHA1Managed();  // Build hangs… commenting out builds fine…
          break;
        case enuHashMethod.SHA256:
          hashAlg = new SHA256Managed();
          break;
        case enuHashMethod.SHA384:
          hashAlg = new SHA384Managed();
          break;
        case enuHashMethod.SHA512:
          hashAlg = new SHA512Managed();
          break;
      }
      return (hashAlg);
    }
  }

Confirmed that this is re-producable in VS2017. Build also hangs. Testing on the new code base about to be released.

Issue identified in #40. Bug fixed in the next release.
