diffie-hellman group exchange sha256 support (wodSSH / wodSSH.NET)

David,

one more thing, I just noticed. This thread is about changes in wodSSH.NET, not wodSFTP.NET. wodSFTP.NET is not yet updated, but will be in next 2-3 days.

Jasmine.

Hi David.

I believe we have updated wodSFTP.NET as well to support your server. Can you request update and try it out?

Hi Jasmine,
we have applied the 2.6.4.160 version of SSH.NET in our software. Unfortunately, we have met an issue with loading this library: WeOnlyDo.Security.Cryptography.KeyManager.dll. The older version of this library (from 2.5.0.130) is working fine. We are able the new version of the library by adding useLegacyV2RuntimeActivationPolicy="true" to App.config, but we would like to avoid it.

Our program is compiled against .NET Framework 4.5.
Code to reproduce:
[code]using System;
using WeOnlyDo.Security.Cryptography;

namespace WeOnlyDoKeyManagmentTest
{
class Program
{
// Program does not work,
// it can be fixed by adding useLegacyV2RuntimeActivationPolicy="true" to App.config (ref. http://stackoverflow.com/questions/1604663/what-does-uselegacyv2runtimeactivationpolicy...
// ex: System.IO.FileLoadException
// message: Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.
static void Main()
{
const string key = @"-----BEGIN RSA PRIVATE KEY-----
...
-----END RSA PRIVATE KEY-----
";
var decrypted = DecryptCertificateFile(key, String.Empty, "RSA");

Console.WriteLine(decrypted);
}

public static string DecryptCertificateFile(string content, string password, string keyType)
{
SSHKeyTypes sshKeyType;
switch (keyType.ToLowerInvariant())
{
case "rsa":
sshKeyType = SSHKeyTypes.RSAKey;
break;
case "dsa":
sshKeyType = SSHKeyTypes.DSAKey;
break;
default:
throw new ArgumentOutOfRangeException(nameof(keyType));
}

try
{
var manager = new KeyManager();
manager.Load(content, password);
return Convert.ToBase64String(manager.PrivateKey(sshKeyType));
}
catch (Exception exception)
{
throw new Exception("Can't load private key.", exception);
}
}

}
}
[/code]

Could you please provide working version? The best option is to compile you library against .net 4.5 (please remember for FIPS version).

Regards,
Piotr
