ssh/id_rsa and the public key is stored in ~/. ssh/id_rsa. pub . The private key should only be kept on your local system and should be encrypted using a passphrase that is at least as strong as any password you would normally use.

Security is easy as only the private key must be kept secret. Maintenance of the keys becomes easy being the keys (public key/private key) remain constant through out the communication depending on the connection. As the number of keys to be kept secret become less.
What is meant by key distribution?
