and install the downloaded software just like a normal software
2.Open PuTTYgen
Just search for the PuTTYgen program and open the program
3.Selecting the parameters
Select the Type of key to generate as RSA
Basically we use RSA because it is used both for encryption and digital signatures and supports 2048 bit
4.Generating
After selecting the parameters click the Generate button
and move your mouse cursor randomly in the empty area until the progress bar fills up to generate your key
5.Saving
After completion of progress bar you can see the following screen just like below
Marked red area is the public key
