Several tools exist to generate SSH public/private key pairs. The following sections show how to generate an SSH key pair on UNIX, UNIX-like and Windows platforms.
Generating an SSH Key Pair on Windows Using the PuTTYgen Program The PuTTYgen program is part of PuTTY, an open source networking client for the Windows platform. To generate an SSH key pair on Windows using the PuTTYgen program: Download and install PuTTY or PuTTYgen. 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.
UNIX and UNIX-like platforms (including Solaris and Linux) include the ssh-keygen utility to generate SSH key pairs.
filename
your choice of file name for the private key:The ssh-keygen utility prompts you for a passphrase for the private key.
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.
The ssh-keygen utility prompts you to enter the passphrase again.
filename
and the public key has been saved as filename
.pub
. It also displays information about the key fingerprint and randomart image.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:
Web push generate keys terminal 3. You can add SSH key to Git using the following commands −.Step 1 − Open Git Bash and get the ssh-agent using the following command.$ eval 'ssh-agent'.Step 2 − Next, add the SSH key to the ssh-agent using the following command$ ssh-add /.ssh/idrsa.Step 3 − Now, run the ssh using the following command, which matches the SSH fingerprint used when logging for the first time.$ ssh -p 29418 @gerrit.wikimedia.orgIn the above screenshot, you can see that xyz123 is a instance shell account name, which is used while creating Gerrit account and Abc123 is a user name of your Gerrit account.
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.
