Private keys are usually encrypted with a password.
$ openssl genrsa
openssl genrsa

With OpenSSL You can derive the public key from the private key.
$ openssl rsa -pubout -in foo.pem
will give you the public key corresponding to the private key.
You also have the ability to generate keys in such a way that one public
key will have multiple private keys and vice versa but those things are not
usually needed.
The other way to list private keys is with the GnuPG command.
$ gpg --list-secret-keys
