PlatformNotSupportedException: 'CspParameters' issues when running tests on Linux

[SidShetye]

Failure: Basic CLI commands like dotnet test or dotnet build don't seem to work.

Expectation:

• dotnet build should build the project(s) based on the platform it's invoked on and folder it's invoked in
• dotnet test should run the test project (nunit 3.x tests should be automatically discovered and executed via Microsoft.NET.Test.Sdk - this seems to be already in place).

Related cleanup suggestions

• two obsolete formatted csproj files (crypto\crypto.csproj and crypto-test\crypto-test.csproj) that throw off the modern dotnet CLI
• also appears to be a crypto\test\crypto.test.csproj and a crypto-test\crypto.test.csproj project adding to confusion.

Hi,

For today, dotnet cannot be used to build this project. There are a few blockers as you've seen. In addition, we still support the legacy PCL profile to ensure this is 100% drop-in compatible with the non-portable version's targets:
https://github.com/onovotny/bc-csharp/blob/netstandard/crypto/src/crypto.csproj#L3

For now, you need to use msbuild to build with msbuild /restore /t:build …

As to the legacy projects, I want to keep them for now until this PR is fully merged since it minimizes conflicts when updating from the source branch.

[SidShetye]

Thanks for the background, can appreciate those pain points.

Till then, how do we test this on linux? dotnet test is the typical go-to ...

[clairernovotny]

For now, the build and test needs to be on Windows, but the resulting library will work anywhere.

[SidShetye]

I needed to verify that assumption. Turns out there indeed are test issues on *nix but thankfully nothing too bad. I got dotnet build and dotnet test working by getting rid of legacy targets (they can just use older builds) in my repo clone. Changes are actually simple if you can look past the "diff" on deleted file. (diff here)

Here is the console log - since the tests have parameterized input, the exact failures aren't clear without diving a bit deeper

On Windows 784 of 788 test pass, on macOS 783 (1 failure) of 788. No idea about the 4 in between (ignored?)

FYI, tried this on Ubuntu 16.04 too. Test failure as follows - assumptions about CAPI being broken x-platform. You can try using Ubuntu on Windows 10 (via WSL)

Haven't had a chance to look at the interop issues, but dotnet build can build this directly now.

[jeremyVignelles]

Hi,
Just happened to me when calling DotNetUtilities.ToRSA(keyParameters) on a Linux on .net core 3.1 .

Do you know of any workaround I can use to create a RSA instance from my RSAParameters instance on linux?

[jeremyVignelles]

I found a workaround:

Instead of calling

var rsa = DotNetUtilities.ToRSA(keyParameters);

I'm using

var rsa = RSA.Create(DotNetUtilities.ToRSAParameters(keyParameters));

and it works.

I'd like to replace this method:

bc-csharp/crypto/src/security/DotNetUtilities.cs

Lines 242 to 249 in 163f40d

	private static RSA CreateRSAProvider(RSAParameters rp)
	{
	CspParameters csp = new CspParameters();
	csp.KeyContainerName = string.Format("BouncyCastle-{0}", Guid.NewGuid());
	RSACryptoServiceProvider rsaCsp = new RSACryptoServiceProvider(csp);
	rsaCsp.ImportParameters(rp);
	return rsaCsp;
	}

with

private static RSA CreateRSAProvider(RSAParameters rp) => RSA.Create(rp);

However, I don't know the implications of doing so and if that can break something else on some platform.

[clairernovotny]

This repo is mirror of the main repo with the only changes being to enable the portable build. For a functional change like you're proposing, I recommend creating an issue here: https://github.com/bcgit/bc-csharp/issues

[clairernovotny]

Closing due to age.
