The basic function is to create public and private key pairs. PuTTY stores keys in its own format in.ppk files. However, the tool can also convert keys to and from other formats. PuTTYgen.exe on Windows is a graphical tool. A command-line version is available for Linux. Just download and install openSSH for windows. It is open source, and it makes your cmd ssh ready. A quick google search will give you a tutorial on how to install it, should you need it. After it is installed you can just go ahead and generate your public key if you want to put in on a server. 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. Sep 26, 2019 To generate an SSH key with PuTTYgen, follow these steps: Open the PuTTYgen program. For Type of key to generate, select SSH-2 RSA. Click the Generate button. Move your mouse in the area below the progress bar. When the progress bar is full, PuTTYgen generates your key pair. Type a passphrase in. Windows will now generate your RSA public/private key pair. The public key will be stored as “idrsa.pub” in the directory you specified. Upload this key to any machines you need to SSH into.
-->To sign an assembly with a strong name, you must have a public/private key pair. This public and private cryptographic key pair is used during compilation to create a strong-named assembly. You can create a key pair using the Strong Name tool (Sn.exe). Key pair files usually have an .snk extension.
Note
In Visual Studio, the C# and Visual Basic project property pages include a Signing tab that enables you to select existing key files or to generate new key files without using Sn.exe. In Visual C++, you can specify the location of an existing key file in the Advanced property page in the Linker section of the Configuration Properties section of the Property Pages window. The use of the AssemblyKeyFileAttribute attribute to identify key file pairs was made obsolete beginning with Visual Studio 2005.
Create a key pair
To create a key pair, at a command prompt, type the following command:
sn –k <file name>
In this command, file name is the name of the output file containing the key pair.
The following example creates a key pair called sgKey.snk.
If you intend to delay sign an assembly and you control the whole key pair (which is unlikely outside test scenarios), you can use the following commands to generate a key pair and then extract the public key from it into a separate file. First, create the key pair:
Next, extract the public key from the key pair and copy it to a separate file:
Once you create the key pair, you must put the file where the strong name signing tools can find it.

When signing an assembly with a strong name, the Assembly Linker (Al.exe) looks for the key file relative to the current directory and to the output directory. When using command-line compilers, you can simply copy the key to the current directory containing your code modules.
If you are using an earlier version of Visual Studio that does not have a Signing tab in the project properties, the recommended key file location is the project directory with the file attribute specified as follows:

In Windows:
1. Open the Command Prompt (Start > Programs > Accessories > Command Prompt).
2. Navigate to the following folder:
C:Program FilesListManagertclwebbincerts
3. Type the following:
openssl genrsa -out rsa.private 1024
4. Press ENTER. The private key is generated and saved in a file named 'rsa.private' located in the same folder.
NOTE The number '1024' in the above command indicates the size of the private key. You can choose one of five sizes: 512, 758, 1024, 1536 or 2048 (these numbers represent bits). The larger sizes offer greater security, but this is offset by a penalty in CPU performance. We recommend the best practice size of 1024.
Generating the Public Key -- Windows
1. At the command prompt, type the following:
openssl rsa -in rsa.private -out rsa.public -pubout -outform PEM
2. Press ENTER. The public key is saved in a file named rsa.public located in the same folder.
Generating the Private Key -- Linux
1. Open the Terminal.
2. Navigate to the folder with the ListManager directory.
3. Type the following:
openssl genrsa -out rsa.private 1024
4. Press ENTER. The private key is generated and saved in a file named 'rsa.private' located in the same folder.
Generating the Public Key -- Linux
1. Open the Terminal.
2. Type the following:
