What Is Putty?

There are many ways to establish a secure SSH connection via Putty to a Linux-based server. The majority and the most basic method out there is using the username and password authentication.

 However, this is prone to dictionary attack via brute force, that’s why sites like AWS (Amazon Web services) and some others uses Public and Private key exchange.

 If you need to connect to a server that only accepts public keys for SSH connection this is a step-by-step tutorial on how to use PuTTY to establish a secure connection via Public keys. 

The idea is to let the server store a public key, and your computer (PuTTY) client will provide a private key to the server for authentication.


assuming you already created a pair of public and private keys. You’ve already added the public keys to authorized_keys on a Linux server

you have an RSA private key as a result of the public and private key self-generated key pair

This tutorial will not convert on how to generate a pair of public and private keys. Because PuTTY doesn’t understand the id_rsa private key we need to convert the private key to a putty client format in .ppk
