hello shubham this side

So Guys today i have very good Topic as we are going to discuss about ssh in LINUX

What is SSH Key and how we can create ssh key over LINUX terminal

So Guys First point , What is SSH ?

SSH full form (Secure Socket Shell)

This is simply known as Secure Socket shell it is crop graphic protocol, it is the

primary one, it is used

to enable Seeker Access, remote server and device can also access all the internet, supose date, you have two laptops, you have

If you wanna connect securely both laptops, so where you can use ssh key to get remote server access

for this purpose, we use SSH key,

I Would like to tell you that SSH key is too Secure form

in which password information share in encrypted form

You can not easily read this information

Even all banks Save , Share user password related infrormation in encrypted form

so guys this is example of SSH, and SSH key used for this purpose

These are few reasons because of these we use ssh key

Secure Access to remote systems

Secure execution of commands on remote systems

Secure remote delivery of software updates

Secure Interactive and automated file transfers

As you can share your all information between to servers or two laptops after get the remote access by the ssh key

and information will be in encrypted form, and nobody can read and access,

and it is difficult to read as compare to password

Auto-login to Servers

IF you server connected through ssh key, so you can easily auto login

basically Two keys comes under SSH key

first is our private key and second is our Public Key

How we can create ssh key over Linux Terminal

We will use this command "ssh-keygen" to create ssh key

How we can create over Linux terminal ,I will show you

If you are working in IT Industry and you need any application access,

so IT team might say share your private key,

so remember you always need to share public key,not private key

because the private key is there, it is a secret information, regarding your system,

does not have to be shared. you have to share the public key only

How you can identify public key or private key

Your Public key will be this " id_rsa1.pub"

Your Private key will be this " id_rsa1

key By the way you can identify

so guys now we do practical on Linux Terminal

so Guys I have Opened my Linux terminal

Simply i have created Linux Ec2 instance on AWS Cloud

I will just press "ssh-keygen" without any Space, then enter

now asking about path where i wanna save ssh key

For Default Save just need to press enter

. that you have already created do you want to overact that

Yes I will just press enter , Again will press enter

Now you can see my SSH Key has created successfully and it is encrypted form

and I am unable to read

Now I Just wanna see ,Public key AND " Private"

Both Key successfully created or not, and on which location both are available .

what is file name

I will just press ls -lrt, no information is coming

We have to use ls -a because this is hide file

Now all hide file are visible after use "ls -a "

Now you can see one folder is create which name is .ssh

I will Open folder

Now I will do listing " ls -lrt" to see the file and folder

I have two files in .ssh folder

First file is "Id_rsa" (Public key), I will Open this

You can copy and share with Anyone individually

This is Public key

Now we talk about Private key, Dont share

We use cat for Open any txt file, will open this file by cat command

can share the public key of your system and ask for the private key, but you do not have to share the private key,

How you can create i have already told you
