Generate Rsa Key Windows Cmd

18.04.2020 admin

If you don't have an existing SSH key that you wish to use, generate one as follows: Open a terminal on your local computer and enter the following: ssh-keygen -t rsa -C. Just press to accept the default location and file name. Enter, and re-enter, a passphrase when prompted.

You can generate a new SSH key for authentication using the following command in Git Bash − $ ssh-keygen -t rsa -C 'youremail@mail.com' If you already have a SSH key, then don't a generate new key, as they will be overwritten. You can use ssh-keygen command, only if you have installed Git with Git Bash. Add your SSH private key to the ssh-agent. If you created your key with a different name, or if you are adding an existing key that has a different name, replace idrsa in the command with the name of your private key file. $ ssh-add /.ssh/idrsa; Add the SSH key to your GitHub account.

This guide contains description of setting up public key authentication for use with WinSCP. You may want to learn more about public key authentication or SSH keys instead.

Configure Server to Accept Public Key

Advertisement

Before starting you should:

Have WinSCP installed;
Know how to connect to the server without public key authentication.

If you do not have a key pair yet, start with generating new key pair.

Connect to your SSH server using WinSCP with the SSH protocol, using other means of authentication than public key, e.g. typically using password authentication.

Once logged in, configure your server to accept your public key. That varies with SSH server software being used. The most common SSH server is OpenSSH.

You can use Session > Install Public Key into Server command on the main window, or Tools > Install Public Key into Server command on SSH > Authentication page page on Advanced Site Settings dialog. The functionality of the command is similar to that of OpenSSH ssh-copy-id command.

Or you can configure the key manually:

Navigate into a .ssh subdirectory of your account home directory. You may need to enable showing hidden files to see the directory. If the directory does not exists, you need to create it first.
Once there, open a file authorized_keys for editing. Again you may have to create this file, if this is your first key.
Switch to the PuTTYgen window, select all of the text in the Public key for pasting into OpenSSH authorized_keys file box, and copy it to the clipboard (Ctrl+C). Then, switch back to the editor and insert the data into the open file, making sure it ends up all on one line. Save the file. WinSCP can show you the public key too.
Ensure that your account home directory, your .ssh directory and file authorized_keys are not group-writable or world-writable. Recommended permissions for .ssh directory are 700. Recommended permissions for authorized_keys files are 600. Read more about changing permissions.

Save a public key file from PuTTYgen, and copy that into the .ssh2 subdirectory of your account home directory.
In the same subdirectory, edit (or create) a file called authorization. In this file you should put a line like Key mykey.pub, with mykey.pub replaced by the name of your key file.

For other SSH server software, you should refer to the manual for that server.

When configuring session, specify path to your private key on SSH > Authentication page of Advanced Site Settings dialog.

Alternatively, load the private key into Pageant.

Cloud providers have typically their own mechanism to setup a public key authentication to virtual servers running in the cloud.

For details see guides for connecting to:

Amazon EC2;
Google Compute Engine;
Microsoft Azure.

You will have to generate a private and a public encryption key in order to securely send the order information to FastSpring.

There are two ways on how to generate these keys. The easy way or the long way. The easy way is only possible, if your server is supporting openssl functionalities needed for encryption key generation. These openssl functionalities will be detected by the plugin and so, depending on your server, you will either see the “Generate private and public key” button in the plugin settings page or you wont. If you see the button, then you will be able to use the easy way, if you don’t then please look at the instructions for the long way.

Easy way

click on the “Generate private and public key” button in the plugins settings
if the key generation was successful, dismiss the alert message and download the public-key.pem file, by clicking on the “Download private and public key” link
save the plugin settings
login to your FastSpring dashboard and navigate to Integrations » Store Builder Library. Upload the public-key.pem file to the Public Certificate option.

That’s it! 🙂

Long way

The private and public keys will have to be generated on your computer, so let’s look at how to generate them.

Generate the private/public keys

The generation of these private/public keys differ, depending on which computer operating system you are using. Please follow the instructions for the OS your computer is using.

macOS and Linux

On macOS and on Linux, you should open the terminal program and execute the commands displayed below:

Create a 2048-bit RSA private key. Don’t share this key with anyone, use it only in the EDD FastSpring plugin settings. This key will be used to encrypt the orders. Use this command to generate the privatekey.pem file which will contain your private key. The file will be created in the position, that the terminal is currently located in (usually your home directory).

openssl genrsa -out privatekey.pem 2048

Create a 2048-bit RSA public key. Only share this key with FastSpring. FastSpring will use your public key PEM file publiccert.pem to decrypt the orders. The file will be created in the position, that the terminal is currently located in (usually your home directory). After you run this command a few short questions will be presented to you, which you can skip, by hitting “enter” key for each of them.

openssl req -new -key privatekey.pem -x509 -days 3650 -out publiccert.pem

Now that you have generated these keys, you have to configure the EDD FastSpring plugin and the FastSpring Dashboard, so look at these instructions in the sections below.

Windows

For generation of these private/public keys your computer needs OpenSSL. Windows does not have that installed by default, so we will have to do that ourselves.

Go to this website: https://slproweb.com/products/Win32OpenSSL.html
In the “Download Win32 OpenSSL” section download the latest appropriate “Light” version of the OpenSSL installer. By “appropriate” I mean the version of Windows you are using (32bit or 64bit). I’m using the 64-bit Windows, so at the time of writing this, the latest version to download is “Win64 OpenSSL v1.1.0f Light”.
Install the downloaded installer file as you would any other windows application (leave the default installation path, because it will be needed later on). In the last step, you can uncheck the donation option and click on “Finish”.

So, the OpenSSL is now installed on your Windows computer and we can generate the private and public keys.

Click on your Windows start button and search for “Command Prompt” (cmd), right click on the “Command Prompt” and choose to “Run as administrator”. Click on “yes”, when the window for the administration conformation pops up.

Copy and paste this command into the cmd and hit enter (this will position the cmd location to your desktop, where we will generate the private/public keys):

cd %userprofile%Desktop

Depending on which version of Windows you have and therefore which version of OpenSSL you installed, you will have to use a specific path to the OpenSSL executable.

By default the paths are:

If you installed the win32 version, the path will be:
C:OpenSSL-Win32binopenssl.exe
If you installed the win64 version, the path will be:
C:OpenSSL-Win64binopenssl.exe

I’m using the win64 version, so I’ll use that path in the example, if you are using the win32, then just change the “64” in the path to “32”.

C:OpenSSL-Win64binopenssl.exe genrsa -out privatekey.pem 2048

Create a 2048-bit RSA public key. Only share this key with FastSpring. FastSpring will use your public key PEM file publiccert.pem to decrypt the orders. After you run this command a few short questions will be presented to you, which you can skip, by hitting “enter” key for each of them.

The smart key allows the driver to keep the key fob in a pocket or purse when unlocking, locking and starting the vehicle. The key is identified via one of several antennae in the car’s bodywork and a radio pulse generator in the key housing. Vehicles with a smart key system also have a mechanical key back-up, usually in the form of a spare key blade supplied with the vehicle. Generally, the key hole is hidden. The key is identified via one of several antennas in the car's bodywork and a radio pulse generator in the key housing. Depending on the system, the vehicle is automatically unlocked when the door handle, trunk release, or an exterior button is pressed. Vehicles with a smart key system fitted are required to have a mechanical backup, usually in.
