2. 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.

3. 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.

4. 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.
