Cannot find DotNetUtilities in BouncyCastle.NetCore

[Korporal]

I'm struggling to leverage numerous published code sample in a .Net Core Web App.

For example creating a RSQCryptoServiceProvider form a raw PEM string.

The reason is that I cannot find (like this person also posted about) any hint of the DotNetUtilities class.

Can anyone suggest anything?

Is there actually a solution? How to do:
rsaParams = DotNetUtilities.ToRSAParameters(privateRsaParams);

It's not clear what version of the library you are using. It should be in Org.BouncyCastle.Security namespace. Possibly DotNetUtilities is missing because it has been compiled with one of the flags that disables it:
#if !(NETCF_1_0 || SILVERLIGHT || PORTABLE)

I suggest copying the method(s) you need from the source code:
https://github.com/bcgit/bc-csharp/blob/master/crypto/src/security/DotNetUtilities.cs

Of course, you may find some of the methods won't compile/work (which would explain why it's missing in your platform/version), in which case you may need to find an alternative way to convert b/w BC and .NET types.

After installing BouncyCastle.NetCore v1.8.2 from NuGet I'm getting this:

The library is referenced correctly:

[EDIT]
I was looking in the wrong folder.
NetStandard2.0 version does NOT have DotNetUtilities class

To anyone else who lands here like I did -- the issue is that BouncyCastle.NetCore is packaged by someone else. Don't use it. The package you want is Portable.BouncyCastle

[RussKie]

It would be great if the repo owners chimed on this issue. 😕

[johnhargrove]

Yeah, that would help. Because now that I'm using Portable.BouncyCastle, the class is present, but it's not actually working on non-Windows platforms, as it's relying on the RsaCryptoServiceProvider constructor that accepts a CspParameters object, which results in a crash on Linux:

System.PlatformNotSupportedException: 'CspParameters' requires Windows Cryptographic API (CAPI), which is not available on this platform.

After I collect more information (and verify that I'm not crazy), I will open a separate issue for this.

@johnhargrove Thank you very much for this! Sad that 17 days have passed, but your new issue isn't addressed.

Sorry, but we're snowed under with TLS 1.3.
