Why would you use something like PGP if you have to send your encryption key unencrypted to the party you are sending to? And if you leave this key out on something like Twitter for example, couldn’t law enforcement or a third party if they gained access to the other persons email still read the contents of the encrypted email by using this key? Doesn’t this defeate the purpose of using encryption?

The public key is kind of like if you sent someone a box with a lock. You have the key, and they can lock the box, but it can’t be unlocked until you get the box back and use your key.
