According to https://docs.microsoft.com/de-de/dotnet/api/system.security.cryptography.cngkey .NET Core should be also possible. But in my setup it keeps complaining it cannot find System.Security.Cryptography. Any hints? |

I think they moved it for core in to Nuget package
https://www.nuget.org/packages/System.Security.Cryptography.Algorithms/

This is great that some additional private key support is being added. For what its worth, I'm currently working on adding ed25519 support though I'm a ways off as I don't a lot of time to work on it (currently have working code to parse openssh v1 key and decrypt it if protected with a passphrase but that's it so far). |
Cool! I'm also on it. Can you share your result so far? |
@darinkes sure, please give me a little time to clean up my code and I'll be happy to share it (It is pretty messy at the moment, I was in trial and error mode expecting to clean it up when I had it basically working). I saw your PR for ed25519, I'm going to add a comment there too |

Also known as:
- ecdsa-sha2-nistp256
- ecdsa-sha2-nistp384
- ecdsa-sha2-nistp521
Works for .NET 3.5 and 4.0 but needs some more testing and tests.
Basically it translate between SSH-Data and Microsoft Crypto API.
Tested with ECDSA-{256,384,521} Hostkeys and ECDSA-{256,384,521}-Pub/Private-Keys
against OpenSSH_7.2p2 Ubuntu-4ubuntu2.4, OpenSSL 1.0.2g 1 Mar 2016.
Keys generated with:
