SSH operates by authenticating based on a key pair, with a private key being on a remote server and the connected public key on a local machine.
When the keys compare, access is granted to the remote user. The word SSH stands for Secure Shell is a method utilized to establish a secure connection between two computers.
There are various methods to generate SSH keys inside Windows 10. You can use different tools but the most famous and the most convenient is PuTTYGen.
In this article, you will learn how to generate an SSH key in Windows 10 using PuTTYGen. So stick this article upto the end you will find the best way.
What Is an SSH Key?
An SSH key (it has a public and private part) is used to attach a client to a server. It is interesting since it avoids having to enter a password every time we want to access a specific server.
The method, once configured, is automatic. An essential point is that we do not have to send the password over the network.
These kinds of keys also reduce the risk of brute force attacks and thus prevent a potential attacker from assuming the credentials accurately.
Safety is an extremely important factor and must always be kept in mind. There are some ways to allow or generate SSH in Windows 10.
In the following section, we will describe how to generate SSH key Windows using PuTTY. But before beginning, let us have some checks to see whether SSH Key exists in Windows or not.
Checking For Existing SSH Keys in Windows 10
Before generating an SSH key, you have to know better to check for existing SSH keys. For checking this you have to follow the below steps -
1. Click windows R and type cmd and click ok then open windows command line
2. In the command prompt environment, kind ssh-keygen.
3. If you do not have any SSH-keygen, you will see this message -
[ssh-keygen’ is not remembered as an internal or external command, operable program, or batch file]
4. The default directory for your SSH keys should be something like this
[ http://c/Users/YourUserName/%20.ssh/id_rsa.pub ]
If you do not have the SSH key then you have to generate the SSH key. So for generating an SSH key you have to follow the below section.
You can generate an SSH key by using PuTTY in an easy way.
What Does PuTTY Mean?
PuTTY is an open-source application creating the use of network protocols like Telnet and rlogin in Windows and UNIX platforms in conjunction with an xterm terminal emulator.
Over a network, PuTTY makes use of all the overhead protocols to allow a remote session on a computer.
It is a famous tool for text-based communication and is also a popular utility for connecting Linux servers from Microsoft operating system-based computers.
If you want to generate an SSH key using PuTTY then go through the next section.
