The public key is calculated from the private key using elliptic curve multiplication, which is irreversible: K = k * G, where k is the private key, G is a constant point called the generator point, and K is the resulting public key.

In this article, we've looked at how we can generate the public key from a given private key using different command-line tools. We've started by demonstrating the ssh-keygen command, which allows us to also convert the public key into different formats in addition to generating it.

Generate RSA Keys Open a shell using Putty or another utility. Use commands to generate an RSA key file. Type the following command to generate RSA keys: ssh-keygen -t rsa. ... Navigate to the. rsakey. folder that you created in step 2b. ... Locate the public key beginning with. ssh. and copy the key.
