#.Net Core SSH keys generator Solution for creation SSH keys (RSA, ECDsa) using .NET.

Supported Platforms

• .NET Standard 2.1
• .NET 5.0
• .NET 6.0

Installation

SshKeysGenerator is a library for .NET and .NET core. It will be available at nuget.

RSA Usage Example

string privateKey;
string publicKey;
string publicPuTTYKey;

using (var key = new RSAGenerator(4096))
{
    privateKey = key.ToPrivateKey();
    publicKey = key.ToPublicKey();
    publicPuTTYKey = key.ToPuTTYPublicKey();
}

Console.WriteLine(privateKey);
Console.WriteLine(publicKey);
Console.WriteLine(publicPuTTYKey);

Output

key.ToPrivateKey()

-----BEGIN RSA PRIVATE KEY-----

ECDsa Usage Example

string privateKey;
string publicKey;
string publicPuTTYKey;

using (var key = new ECDsaGenerator("nistP521"))
{
    privateKey = key.ToPrivateKey();
    publicKey = key.ToPublicKey();
    publicPuTTYKey = key.ToPuTTYPublicKey();
}

Console.WriteLine(privateKey);
Console.WriteLine(publicKey);
Console.WriteLine(publicPuTTYKey);
