 * Private key: can open the box
 * Public key: can lock the box
 
-Caveats:
+The idea works on the principle that public keys are public so anyone can lock a message down but only the owner/creator of that public key can open those locked messages with their private key.
 
-Public keys contain a unique signature, which can be used to _sign_ a message. Even though everyone can open the message they also know who locked the box.
+## Public Keys
 
-Imagine then, lock the box with private key(secure) and sign it with the public key(authorized).
+Can be used to open something if it was locked with a private key.
 
+## Private Keys
 
+If used to lock something the public key can be used to then open the box.
+_The catch_: that message is also signed so we know exactly who the message is coming from.
+
+## Both together
+
+> Message => Lock(message, private key)
+
+_Sign_ the message
+
+> Signed Message => Lock(signed message, public key)
+
+Lock the message like normal
+
+Once the intended person has the package they:
+
+* Open it with their private key
+* Check the signature 
+* Find the public key for that signature
+* Open the remaining layer with the public key
+
+That last part only works because locking with a private key allows the public key to open the box afterwards.
