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.
So, it seems a developer on our team deleted the public key for our App-Production.pem key in our.ssh/authorizedkeys, so the default AWS Key Pair no longer works, breaking our deployment pipeline. Where can I find the public key to add back to authorizedkeys?Is it possible to do this without having to boot a fresh instance? To use a single SSH key pair for all your AWS Regions, first generate a public SSH key from a private SSH key. Then, import the key into each of your AWS Regions. If you don't have one already, begin by creating an SSH key pair. Use ssh-keys for authentication with MobaXterm. This post is older than a year. Consider some information might not be accurate anymore. First step is to generate the ssh key, therefore open a local terminal and generate a key (rsa) with this command. The second step is to export the public key to the servers, with respective logins.
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:
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).Key file generator rom mame. 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.
