DotNet Core SSH KeyGen

Build status NuGet version (SshKeyGenerator)

After searching around for a solution to creating SSH keys using C# and dotnet core I came across the following stackoverflow posts which explain how to convert from RSACryptoServiceProvider to values suitable for use with ssh.

Supported Platforms

  • .NET 4.5 (Desktop / Server)
  • .NET Standard 2.0
  • .NET Standard 2.1
  • .NET 5.0
  • .NET 6.0

Installation

SshKeyGenerator is a library for .NET and is available on NuGet:

Install-Package SshKeyGenerator

or

dotnet add package SshKeyGenerator

Usage Example

var keygen = new SshKeyGenerator.SshKeyGenerator(2048);

var privateKey = keygen.ToPrivateKey();
Console.WriteLine(privateKey);

var publicSshKey = keygen.ToRfcPublicKey();
Console.WriteLine(publicSshKey);

var publicSshKeyWithComment = keygen.ToRfcPublicKey("user@domain.com");
Console.WriteLine(publicSshKeyWithComment);

Sample Output

keygen.ToPrivateKey()
-----BEGIN RSA PRIVATE KEY-----

Export Methods

There are three methods which can be used to export SSH key data for use by other libraries such as FxSsh:

  1. byte[] ToBlobs : Export as Blobs
  2. string ToB64Blob : Export blobs as base64 string
  3. string ToXml : Export as XML string

Export methods usage:

// Create a new instance 
var keygen = new SshKeyGenerator.SshKeyGenerator(4096);

// Get Base64 encoded keys with private key
var base64Keys = keygen.ToB64Blob(true);

// Use in a SSH server. e.g. FxSsh
var server = new SshServer();
server.AddHostKey("ssh-rsa", base64Keys);
