Certificates - Create a Public and Private set of Certificates

For an RSA key:

ssh-keygen -t rsa

or for a DSA (Digital Signing Algorithm) key:

ssh-keygen -t dsa

NOTE: When asked for a pass phrase leave blank unless absolutely required,

This will create two files: id_dsa and id_dsa.pub. The pub file is the public key and will be placed on the remote server.
