PuTTYgen is an key generator tool for creating SSH keys for PuTTY. It is analogous to the ssh-keygen tool used in some other SSH implementations. The basic function is to create public and private key pairs. PuTTY stores keys in its own format in.ppk files. Jun 22, 2012  Generating a key pair provides you with two long string of characters: a public and a private key. You can place the public key on any server, and then unlock it by connecting to it with a client that already has the private key. When the two match up, the system unlocks without the need for a password. To generate the public/private key pair, enter this in the Command Prompt: ssh-keygen At the first prompt, “Enter file in which to save the key,” press Enter to save it in the default location. Generating Your SSH Public Key. Many Git servers authenticate using SSH public keys. In order to provide a public key, each user in your system must generate one if they don’t already have one. This process is similar across all operating systems. First, you should check to make sure you don’t already have a key. Mar 28, 2014  SSH private / public key pair & self sign certificate. 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.

SSH allows for both password based authentication, as well as public key authentication. Public key authentication is generally regarded as being more secure, as it isn’t as prone to brute force login attempts (if you disable password based authentication). The private key can also have a passphrase associated with it, which makes public key authentication even more secure if needed.
Sometimes cloud servers will let you put a public key in as a authorized authentication key when the cloud server is created, preventing the need for password based authentication to be enabled by default.
Generate a new SSH public and private key pair:

Mar 31, 2018 Generate public key and store into a file It is a simple one liner command to generate a public key from a private key, so lets say our private key is named ‘user@myserver.key’ and we want to generate the public key and name it ‘authorizedkeys’. Below is the command to do this. To extract public key from the private key file into separate public key file you use your openssl rsa -in private.pem -pubout -out public.pem command. When you produce a public key this way, it is extracted from the private key file, not calculated.

“Identifying comment” can be any string that will assist in determining which key this is. “username@hostname” of the machine where you are connecting from would be a good example.
eg:

This will generate two files, “keypair” and “keypair.pub”. “keypair” being the private key that you need to keep secure, and “keypair.pub” being the public key, that can be put on servers that you want to be able to log into with the private key.
Change the filename to suit your needs. This example uses “keypair” for the examples.
The contents of the public key file “keypair.pub” can be inserted into the ~/.ssh/authorized_keys file on the machine that you want to be able to connect into remotely. This must be done for the specific user.
Insert public key into authorized keys
View the contents of the public key file:

eg:

Take note of the output, and copy it into the clipboard if possible, or use some other method to get this file/data onto the remote machine, as it will be used in the next step.
On the remote server you want to be able to log into:

If you have chosen to copy the public key file to the remote host instead, you can issue the following command instead:

Logging into remote ssh server using the private key file
To connect to the remote host using SSH you can use the following command: /windows-xp-pro-product-key-generator-sp2.html.

This will use the private key called “keypair” created earlier, and assuming the remote server has the public key added to the “user” users authorized_keys file, you should be able to log into the remote system.
