How to generate ssh key using putty-tools

How to generate ssh key using putty-tools?

Simple, just follow the tutorial bellow.

Why it’s better to have a ssh key and just use it?

Better security and safer files transfer.  

Let’s start:

First we need to install putty-tools, on ubuntu you do this by using apt-get command:

sudo apt-get install putty-tools

After you’ve successfully installed putty-tools, we have to generate our private key, it’s better to suffix your private key with ppk as follows:

puttygen -t rsa -b 2048 -C "user@host" -o keyfile.ppk

Then we need to generate the .pem file which will be used to transfer files remotely, so you can skip this step if you don’t need it.

puttygen keyfile.ppk -O private-openssh -o keyfile.pem

After we’ve successfully done all the steps above we have to generate our .pub file and copy it to the remote server, otherwise the remote server won’t recognize us.

puttygen -L keyfile.ppk > keyfile.pub

Finally, when we need to connect to the remote server we have to add the .ppk file to the ssh command and the server will recognize us.
