@unaizorrilla @adamsitnik Could you do a review? This issue is important because the previous version did not support modern .NET add all. The lack of RSA-SHA256 is also a huge problem. For example, the default Azure settings make it impossible to use the AspNetCore.HealthChecks.Network library. Users must enable deprecated algorithms in the SSH configuration on the server.
