I saved them to My Documents\sshkeys and named the public key “puttykey.pub”. Click “Generate”.Ĭlick “Save private key” and “Save public key” to save each. Generate SSH Key pair using PuTTY’s puttygen.exe (Windows)Ĭlick “Start | Run” and launch “C:\Program Files (x86)\PuTTY\puttygen.exe”Įnsure that key type is “SSH-2 (RSA)” and key length is “2048”. Leave Passphrase blank for true passwordless authenticationĬlick “Next” after the RSA key is generatedĬhoose where to save your key pair, I created a folder in My Documents named “sshkeys”. You have been warned.īefore you start, choose “Options | Global Options | SSH2” from the menu to see if you have already generated and configured a SSH key pair.Ĭhoose between DSA and RSA key generation, RSA for this tutorial. Important If you have already created a private/public key in the past using SecureCRT make sure you backup your keys or just use the existing key pair. Generate an RSA key pair using SecureCRT (Windows) Next, skip down to Install the public key Warning: Permanently added '192.168.1.99' (RSA) to the list of known password: Step 2: Copy the public key to the MikroTik router scp ~/.ssh/id_rsa.pub authenticity of host '192.168.1.99 (192.168.1.99)' can't be established. Your identification has been saved in /home/osboxes/.ssh/id_rsa. Generate an RSA key pair on ubuntu linux Step 1: Run ssh-keygen ssh-keygen -t rsaĮnter file in which to save the key (/home/osboxes/.ssh/id_rsa):Įnter passphrase (empty for no passphrase): SSH from a Linux host, Putty on Windows, or SecureCRT on Windows. This tutorial is really three articles in one, pick the one that fits your environment.
This MikroTik tutorial will guide you through the process of configuring authentication with RSA keys. SSH Public Key Authentication on RouterOS using DSA keys has been supported for a long while.
In RouterOS 6.31, MikroTik introduced support for RSA keys for authentication so I decided to give it a test. A Step-by-Step guide to configure SSH Public Key Authentication on a MikroTik router using an RSA keys
