Generate Ssh Public Key And Private Key Pem
I was recently in a meeting where a person needed to generate a private and public key for RSA encryption, but they were using a PC (Windows). This is something that is easily done via a terminal using ssh-keygen on Mac and Linux, however on Windows this tool is not easily accessible to the non-technical person.
To generate the missing public key again from the private key, the following command will generate the public key of the private key provided with the -f option. $ ssh-keygen -y -f /.ssh/idrsa /.ssh/idrsa.pub Enter passphrase: The -y option will read a private SSH key file and prints an SSH public key to stdout. In case you travel and can’t carry your laptop with you, just keep your private key on a USB stick and attach it to your physical keychain. Your server will be much safer this way. Generate Public/Private SSH Key Pair. Open Command Prompt from the Start Menu and type. If you're using Windows, you can generate the keys on your server. Just remember to copy your keys to your laptop and delete your private key from the server after you've generated it. To generate an SSH key pair, run the command ssh-keygen. It will look like this when you run it: laptop1: yourname$ ssh-keygen Generating public. Save the text file in the same folder where you saved the private key, using the.pub extension to indicate that the file contains a public key. If you or others are going to use an SSH client that requires the OpenSSH format for private keys (such as the ssh utility on Linux), export the private key: On the Conversions menu, choose Export.
One of the most common forms of cryptography today is public-key cryptography helps to communicate two system by encrypting information using the public key and information can be decrypted using private key. These keys are using mainly on login to server securely and also transferring data securely.
We can generate these private public keys by various ways.
1) By using openssl.
with password encryption
Generate public key:
2) By using ssh keygen
3) using putty-gen for windows.
Download puttyGen from http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html and run it.

You can select one of the key types, SSH-1, SSH-2, and SSH-2 DSA.
Online key generator for pc games. SSH-2 is probably better than others but you have to make sure if your system supports SSH-2, if your system ( server) doesnt support it then you better off with SSH-1.
Level of encryption can be set from “Number of bits in a generated key” . Security level can be enhance by using 2048 but again make sure where you are using it and thus follow the recommendation for this value. I prefer 2048 but even with 1024 is much more secure.
Convert Ssh Key To Pem
Click on generate to create keys. Move your mouse over the empty space to help puttygen to genereate random variables.
Once the key is generated you will see following window.
Generate Private And Public Key
If you want to login without password ( in case of ssh login) you can put your passphase empty. click on Save Public key and Save private key to save your keys.
When you save private key it will be saved in ppk format which you can use putty to login to your system.

If you want to use ssh to login with these generated key / pair then
copy public key ( mykey.pub) to .ssh/authorized_key.
