RSACryptoServiceProvider poor performance in Unity compared with Visual Studio
Steps to reproduce:
1. Download and in Unity open project named "RSAPerformanceIssue".
2. Open scene named "test" and press Play button.
3. In console window should appear message: "Test starts...".
4. Wait for some time until you will see this message: "Test finished: 8570ms"
(numbers can be different)
5. Download project named "RSAPerformanceIssueVS" and in Visual Studio 2015 open script named "RSATest.cs".
6. In Visual Studio 2015 click Start button and notice message "Test starts..."
7. After some time message this appears: "Test finished: 197ms".
(numbers can be different)
Actual result:
Number is quite small in Visual Studio compared to the number in Unity's console window.
Expected result:
Unity in play mode should not by slowed down by "ExportCspBlob()" method of assymetric encryption algorithm (RSA) and work as fast as Visual Studio.
Reproduced on:
5.1.0f3, 5.2.4f1, 5.3.4f1, 5.4.0b11
The issue will be addressed as part of Mono Runtime upgrade effort.

Could not locate RSAPerformanceIssue open project to check details, but I am experiencing this issue using Unity 2020.3.3f1. However, I was able to partially overcome the delay by setting the static field RSACryptoServiceProvider.UseMachineKeyStore to true and setting the related CspParameters.KeyContainerName to a constant value. The first time the code loads, the delay exists, but no delay for subsequent loads using the same KeyContainerName.
