ssh: Retrieve public key from secret key.
$ ssh-keygen -y -f ${~--ssh-OpenSSH_private_key}
try on your machine
The command ssh-keygen -y -f ${~--ssh-OpenSSH_private_key}
is used to generate the public key from a specified private key file.
Let's break down the command:
ssh-keygen
is the command-line utility used for generating and managing SSH keys.-y
is an option that tellsssh-keygen
to output the public key corresponding to the private key file specified.-f
is another option that specifies the input private key file from which the public key should be derived.${~--ssh-OpenSSH_private_key}
is a placeholder for the actual path and filename of the private key file.
In summary, the command takes a private key file as input and produces the corresponding public key as output. The resulting public key can be used for things like SSH authentication or adding it to a server's authorized keys list.
