Below is the complete guidance about how to generate RSA key in Windows operating system: Once you install the PuTTY on your machine, you can easily run PuTTYgen. For the same, go to Windows - Start Menu - All Programs - PuTTY - PuTTYgen. Here's how you can generate SSH public/private keys on Windows. You probably used PuTTY or at least heard about it. It’s an excellent utility and has been a favorite SSH client for years. In the “/.ssh/authorizedkeys” file (or rather, pasted/added to this file). To open this key, to copy, and then paste, wherever necessary. Create an SSH public key on Windows. In this section, you use PuTTY Key Generator to create a public SSH key and private key pair to use when you create a secure connection to Linux machines in your Azure Stack Hub instance. PuTTY is a free terminal emulator that can.
PuTTYgen is a tool used for generating public and private SSH keys which are its fundamental function. Though it collects keys in its own file format i.e. .ppk files, keys can also be transformed to any other file format quickly. It is available for the various operating system, i.e. Windows, Linux, Mac, etc. PuTTYgen.exe is the graphical tool on Windows OS. While on the other side, Linux OS has the only command-line version.

Various Ways to Use RSA Key Pair
RSA key pair generated through PuTTYgen is used in two various ways defined as below:
- To assign while creating a new cloud server
You can choose the public key from the given list of keys at the time of creating cloud server. If you don’t find your key in that list, then first add and then assign it. - Assign to an existing cloud server
At the time of connecting to the cloud server, first of all, you need to tell PuTTY to use it for utilizing your newly created RSA key pair.

Various Command Line Options of PuTTY in Linux
Below is the list of important command line options for PuTTY in Linux operating system.
PuTTYgen [-t keytype [-b bits] [-q] keyfile]
[-C new-comment] [-P]
[-O output-type -p -l -L]
[-o output-file]
Options: Microsoft office 2013 standard key generator download.
- Keyfile – It is the name of the existing key file to read at the time of changing the current key.
- -t keytype – This command specifies the type of the key to creating. Its acceptable values are RSA and dsa.rsa1.
- -b bits – This command specifies a total number of bit in a particular key. 1024 is the perfect size for DSA key, while 2048 or 4096 are the perfect size for RSA keys.
- -q – This command suppresses the message about progress at the time of key generation.
- -C new-comment – This command is used to specify the comment to describe the key. It can be used for new and/or existing key. Key operation is not affected by comment. However, it is used to recognize the key owner, it’s not reliable completely as any value can be applied to it.
- –P – This command is used to update the passphrase of a key. Passphrase helps to encrypt the private key. As passphrase can’t be add or update on command line, it prompts a new passphrase tool to alter it.
- –old-passphrase-file – The old password of the key remains in this file. This is used when the key is protected by a passphrase.
- –new-passphrase file – This file entails the new passphrase of the key. This command comes in the action either at the time of generating new key or while applying –P command to change the passphrase.
- -O output-type – This command defines what to give in output. By default, the private key is the output.
Thus, above are the prominent commands of PuTTYgen in Linux operating system. There are many other commands also available to perform a various task from the command prompt in Linux at flank speed.
SSH keys are a means of authenticating a user to an SSH server without using a password. Each “key” is actually a key pair consisting of a public key and a private key.
Keys are more secure than passwords because they are significantly more complex. While a password of eight characters is 72 bits long, SSH keys are often 2048 bits or longer. This longer string has many more possible permutations and therefore takes much more time to crack with a brute force attack.
If you require SSH access for multiple users, the use of SSH keys instead of individual logins can bypass many of the headaches involved in user management without violating PCI DSS. For details, see What are the advantages of using SSH keys to control access for multiple users?
Method

The process involves generating a pair of SSH key files containing a private key and a public key. The private key is known only to the user’s computer; the public key will be known to the server. Each key is useless without the other; therefore, only individuals with both the private and the public key can gain access to the server, and the private key is never revealed to the server.
Take special care to not lose the private key. A lost private key cannot be replicated; therefore, users cannot access the server until an administrator generates a new key pair. If you lose access to your server due to a lost key, contact our Support Team for assistance.
Though there are varying methods of generating SSH keys on machines using Windows, this one uses PuTTY Key Generator.
