Sep 11, 2018  Certificate signing requests (CSR) are generated with a pair of keys – a public and private key. Only the public key is sent to a Certificate Authority and included in the SSL certificate, and it works together with your private key to encrypt the connection. Anyone can have access to your public key, and it verifies that the SSL certificate is authentic. The private key for an SSL Certificate is something that is generated when you create a CSR. During the CSR creation process, the server will usually save the private key in one of its directories.

A lost SSH public-key or a web service generates an SSH key but does not provide the public-key part to you. What to do now? There is a solution for this situation.

When you have an SSH key you need the public key to setup SSH passwordless login with SSH-key. But if you have lost the public key part but still have the private key, there is a way to regenerate the key.

With the public key missing, the following command will show you that there is no public key for this SSH key.

Symmetric Key

The -l option instructs to show the fingerprint in the public key while the -f option specifies the file of the key to list the fingerprint for.

To generate the missing public key again from the private key, the following command will generate the public key of the private key provided with the -f option.

The public key part is redirected to the file with the same name as the private key but with the .pub file extension. If the key has a password set, the password will be required to generate the public key.

To check the details of the generated public key execute the following command as shown above.

The output of this command shows the key size as the first column, the fingerprint as the second column and after the file name, the type is shown in brackets. In the example above, a 4096 bit RSA key.
