How to extract the public key from a .pem certificate for use with openssh

Navigation
-1

I have a rsa private key formatted as PEM issued by the Amazon Key Generation Service (AWS). I need to extract the public key, from the private key to use in the ~/.ssh/authorized_keys file in other instances.

How do I extract the public key having the private key?

To extract the public key, use the command ssh-keygen as below: 

ssh-keygen -f chave_privada.pem -y > chave_publica.pub
