How to Recover SSH Public Key from Private Key
To recover the SSH public key from a private key, you can use the ssh-keygen command in terminal.
1. Open a terminal window and navigate to the directory where your private key is located.
2. Type the following command and press Enter:
ssh-keygen -y -f [private key file name]
3. The command will output the corresponding public key in the format "ssh-rsa [public key] [username]". This is the public key that corresponds to the private key you provided.
4. You can also use the ssh-keygen command to convert the private key to a different format, such as OpenSSH or PuTTY, by using the -m option. For example, to convert a private key to the OpenSSH format, you can use the following command:
ssh-keygen -y -f [private key file name] -m pem
5. In this case, the command will output the public key in the OpenSSH format, which can be used with other SSH clients that support this format.
Note: If the private key is password protected, you will be prompted to enter the password before the command can generate the public key.
