SSH Keys Generation

SSH Keys Generation

SSH permits the webserver to access the (CLI) command-line interface. It provides you with a perfect remote connection and security for the webserver. SSH program has two setups such as SSH key pairs and SSH keys to get connected using a password. You can even say it is a challenge in cryptographic history that gives an SSH connection for perfect integration.

Does your operating system have SSH key pair? Here we are giving you a list of the process to create SSH key pair:
  • PowerShell Windows
  • PuTTY Windows
  • macOS Terminal and Unix
How to use PowerShell in Windows for generating SSH Keys?

You can access using PowerShell or command prompt which gives OpenSSH in Windows.

Step 1: Tap on the “Start Menu” and then enter as PowerShell. Choose the PowerShell as per your requirement and tap on the option “run as administrator”.

Step 2: Now, do SSH key pair generation

Step 3: You will get a prompt that says “Enter file in which to save the key”. So, now you need to tap on the button “Enter” on your keyboard.

Step 4: It shows a prompt again for entering a passphrase so, tap on the “Enter” button.

Step 5: Again for confirmation of the passphrase the prompt will be displayed in front of you. To confirm the passphrase by typing it again + give a click on Enter button.

Step 6: You will get a result like:

Enter file in which to save the key (C:\Users\/.ssh/id_rsa): Enter passphrase (empty for no passphrase):
Enter the same passphrase again:
Your identification has been saved in C:\Users\/.ssh/id_rsa. Your public key has been saved in C:\Users\/.ssh/
Step 7: Make sure whether the permission you gave is right or not

cd .ssh
icacls /inheritance:r
icacls /grant:r username:"(R)"
You have now created SSH key pair with PowerShell in Windows.

PuTTY Windows SSH key generation:

We recommend using one of the best SSH access called PuTTY to generate an SSH key.

Follow the below steps please:

Step 1:
Now, try to open the application “PuTTYgen”. It will ask you to select the type of key generation so choose the one called “RSA”.

Step 2: You will get a list that shows key generation in bits of number chooses the one “4096”.

Step 3: Tap on the option “Generate”. Make a full round on the key section to bring a full progress bar.

Step 4: Go to the section “Key Comment” for identifying the SSH key pair.

Step 5: In the field key passphrase just type the passphrase for security purpose also it asks to enter the passphrase again for confirmation.

Step 6: Tap on the button “Save private key” and “Save public key”. You save the private and public key in the directory “user’s.ssh”.

That’s it! You have completed the generation of the SSH key pair using PuTTY Windows.

macOS Terminal or Unix SSH Key Generation:

Step 1:
Go to your list of applications and choose “Terminal”. Type below command in your terminal:

ssh-keygen -t rsa -b 4096
Step 2: You will get a prompt saying “Enter file which to save the key”. Enter the passphrase which is required for your security purpose and the enter button “Enter”.

Step 3: It will ask you to confirm the passphrase again. Once confirmed you will receive a command type of SSH key generation like below:

userna5@localhost ~ $ ssh-keygen -t rsa -b 4096
Generating public/private rsa key pair.

Enter file in which to save the key (/home/userna5/.ssh/id_rsa): Enter passphrase (empty for no passphrase):

Enter the same passphrase again:

Your identification has been saved in /home/userna5/.ssh/id_rsa.
Your public key has been saved in /home/userna5/.ssh/
Step 4: Make sure the given SSH permission is correct or not by using the below command:

chmod 0700 ~/.ssh
Step 5: Go to SSH folder for correcting the permissions if not:

chmod 0600 ~/.ssh/*
Overall, we have given you three configuration to generate SSH key pair. I Hope, it will be very useful for you.
