SSH Key
What is SSH Key?
• A technique called Secure Shell (SSH) is used to provide secure 
communication between two devices across an unprotected 
network. An SSH key is a digital identity that the SSH protocol 
uses for authentication. It consists of two cryptographic keys—a 
public key and a private key. Although the private key is 
maintained secretly on your computer, the public key is 
distributed to the servers you wish to access.
• A challenge is sent to your computer by a server that employs SSH 
key authentication when you attempt to access it. With your 
private key, your computer creates a response to the challenge 
and transmits it back to the server. The server then uses the public 
key it has stored to verify the answer. The server allows access to 
your PC if the answer is legitimate.
Creating an SSH Key
• Launch a terminal window.
• Hit enter after typing "ssh-keygen."
• A filename for the key must be entered when requested. 
To accept the default name or to input a different name, 
press enter.
• A passphrase entry prompt will appear. While it's optional, 
this step gives your key an added measure of protection. 
Make sure your passphrase is strong if you decide to use 
one.
• Your computer will produce and store both your public and 
private keys.
Conclusion
In conclusion, the SSH key is a crucial technology that offers a safe method 
of logging onto distant servers. It is significantly safer than having a 
password and makes it simple to log in since you don't need to remember 
one. It is particularly helpful for automation since you can use programs to 
automatically log into distant servers. I urge you, if you haven't already, to 
create an SSH key for your devices and begin using this technology to 
increase the security of your remote logins.
 
Understanding the fundamentals of public key cryptography and how the 
key pair works is crucial for using SSH keys. The security of your remote 
logins may be substantially enhanced, and you can take charge of your 
online security by creating an SSH key and utilizing it to enter distant 
servers.
