Lets say you have a private/public key pair that you use to login to your server via SSH and you lose the public key, either it was deleted or corrupt and you don’t want to have to regenerate a new pair what options do you have? In this post I will demonstrate how to regenerate a public key from the corresponding private key that you still have.

Sep 18, 2019  Enables the SSH server for local and remote authentication on the Device and generates an RSA key pair. Generating an RSA key pair for the Device automatically enables SSH. Mar 30, 2020 Configure SSH on Cisco Router or Switch. To configure SSH on Cisco router, you need to do: Enable SSH on Cisco router. Set Password for SSH. Force remote access to use SSH. Enable Password Encryption. Add domain name Server (DNS). Add Username and Password.

Fortunately, modern cryptography gives us just the right tool for this: We can use RSA signature verification to sign the licensing data with a private key, then verify the signature with an associated public key. The signatures should be part of the license key. The product should validate the license keys with the corresponding public key. This way, even if someone has full access to your product's logic, they cannot generate license keys because they don't have the private key. Generate licence key using c. Dec 24, 2015  Generate a certificate. To use digital signature, first of all, we need a pair of RSA keys. Private key for system owner to sign the XML file. And the public key for end user's application to verify the signed XML license file. A easy way is to use 'makecert' command to generate the certificates which we need to sign and verify the XML license file.

Jun 28, 2007  There are four steps required to enable SSH support on a Cisco IOS router: Configure the hostname command. Configure the DNS domain. Generate the SSH key to be used. Enable SSH transport support for the virtual type terminal (vtys). Any IOS which is a crypto IOS(ssh feature) will have this automatically generated on the switch/router. This crypto is what we use for ssh login. You can also generate one using command 'crypto key generate rsa general-keys modulus 1024 '. You have now learned how to configure the SSH server on your Cisco IOS router or switch and how to use the SSH client. SSH is a secure method for remote access to your router or switch, unlike telnet. SSH requires a RSA public/private key pair. Aug 22, 2013. Jan 26, 2018 DETAILED STEPS Step 1. Enables privileged EXEC mode. Enter your password if prompted. Enters global configuration mode. Specifies the RSA key pair to be used for SSH. A Cisco device can have many RSA key pairs. Enables the SSH server for local and remote authentication on.

Generate public key and store into a file

It is a simple one liner command to generate a public key from a private key, so lets say our private key is named ‘user@myserver.key’ and we want to generate the public key and name it ‘authorized_keys’. Below is the command to do this.

2	user@server:~$chmod644/home/user/.ssh/authorized_keys

At this point we are all set to begin using our private key to login to our server again. If you have any questions about this post please leave a comment below and if this helped you at all please share it on social media!
