Apr 14, 2020 We will use an ssh public key to authenticate your identity. In this method of authentication you generate a public key and a private key. The private key stays on your computer (in this case your AWS instance) and the public key is given to 3rd parties who will want to verify your identity (in this case GitHub). Create the SSH tunnel with Pageant (Windows) Pageant is an SSH authentication agent for PuTTY, PSCP, PSFTP, and Plink. Pageant stores your private key, and as long as it is running, it provides the unlocked private key to PuTTY or other tools like PhpStorm. You can find the Pageant icon in the Windows taskbar.
Y This option will read a private OpenSSH format file and print an OpenSSH public key to stdout. Specify the private key with the -f option, yours might be dsa instead of rsa. The name of your private key probably contains which you used. The newly generated public key should be the same as the one you generated before. To install the public key, Log into the server, edit the authorizedkeys file with your favorite editor, and cut-and-paste the public key output by the above command to the authorizedkeys file. Save the file. Configure PuTTY to use your private key file (here keyfile.ppk). Then test if login works. See configuring public key authentication for.
One effective way of securing SSH access to your cloud server is to usea public-private key pair. This means that a public key is placed onthe server and a private key is placed on your local workstation.Using a key pair makes it impossible for someone to log in by using justa password, as long as you set up SSH to deny password-basedauthentication.
This article provides steps for generating RSA keys by using PuTTYgen onWindows for secure SSH authentication with OpenSSH.
In Windows, use PuTTYgen to generate your public and private keys.
You can use the RSA key pair in the following ways.
When you create a cloud server, you can assign a public key from the list of keys.If your key is not already in the list, you may add it, and then assign it.
Add a new public key to the list
Assign a public key
To make use of your newly generated RSA key pair, you must tell PuTTY touse it when connecting to your cloud server.
To edit the file (or create it), run the following command on the cloud server:
Paste the text onto its own line in the file.
You must have the key available in your clipboard to paste it. The key and itsassociated text (the ssh-rsa identified at the start and the comment at the end)must be on one line in the file. If the text is word-wrapped onto multiple linesan error might occur when connecting.
If you created the authorized_keys file, change its permissionsafter you’re done editing it by running the following command:
Open PuTTY, and go to the SSH > Auth section.
Browse to the location of the key file, and load the private key.
Go to the Session page, and save the session. This saves the configurationso that PuTTY uses the key every time that you connect to your cloudserver.
After you save your session, your key is loaded automatically when youconnect to your server.

The PuTTYgen program is part of PuTTY, an open source networking client for the Windows platform.
To download PuTTY or PuTTYgen, go to http://www.putty.org/ and click the You can download PuTTY here link.
As the key is being generated, move the mouse around the blank area as directed.
Note:
While a passphrase is not required, you should specify one as a security measure to protect the private key from unauthorized use. When you specify a passphrase, a user must enter the passphrase every time the private key is used.
.ppk
(PuTTY private key).Note:
The.ppk
file extension indicates that the private key is in PuTTY's proprietary format. You must use a key of this format when using PuTTY as your SSH client. It cannot be used with other SSH client tools. Refer to the PuTTY documentation to convert a private key in this format to a different format. Make sure you select all the characters, not just the ones you can see in the narrow window. If a scroll bar is next to the characters, you aren't seeing all the characters.
.pub
extension to indicate that the file contains a public key.ssh
utility on Linux), export the private key:.ppk
format, using an extension such as .openssh
to indicate the file's content.
