SshNet.PuttyKeyFile

SSH.NET Extension to read and use Authentication Keys in PuTTY-Format

Status

WIP

Supports PPK v2 and v3

.NET Frameworks

• .NET 4.0
• .NET 4.6.2
• netstandard 2.0

.NET 4.0 Note

PPK v3 encryption is not supported on .NET 4.0

Keys

• ssh-ed25519
• ecdsa-sha2-nistp256
• ecdsa-sha2-nistp384
• ecdsa-sha2-nistp521
• ssh-rsa with 2048, 3072, 4096 or 8192 KeyLength

Key Encryption

• None
• AES256-cbc

Usage Example

var key = new PuttyKeyFile("my-key.ppk");

using var client = new SshClient("ssh.foo.com", "root", key);
client.Connect();
Console.WriteLine(client.RunCommand("hostname").Result);

Automatically load the key based on file contents

using Renci.SshNet;
using SshNet.PuttyKeyFile;

var keyText = "<ssh key contents>";
IPrivateKeySource key = PuttyKeyFile.IsPuttyPrivateKey(keyText) ? new PuttyKeyFile(keyText) : new PrivateKeyFile(keyText);
// or with passPhrase
var passPhrase = "<ssh key password/passphrase>";
IPrivateKeySource key = PuttyKeyFile.IsPuttyPrivateKey(keyText) ? new PuttyKeyFile(keyText, passPhrase) : new PrivateKeyFile(keyText, passPhrase);

using var client = new SshClient("ssh.foo.com", "root", key);
client.Connect();
Console.WriteLine(client.RunCommand("hostname").Result);
