A needs to send/give B the ciphertext somehow, email, snail mail,

same secret key, can use said ciphertext to decrypt it. So, if you
notice the online program has a ciphertext only, without a link prefix.
Say this example: I am encrypting the message on my local host using the
default key:

 Basically, that is outside of the scope of my symmetric cipher. Secure key exchange is something else, another beast so to speak. However, once a key is exchanged, securely, then it can be used for my cipher or any other symmetric cipher? Fair enough?

Actually, I think that is a rather normal way to do things? Gain the key, then use the symmetric cipher with said key?
