 Simplest, but if you send the key in plaintext then you might as well
send the data in plaintext - either could be intercepted!

 Better is for them to send you a public key, you encrypt the data
with that and send it to them, then they decrypt it with their private
half of the key. The data is always sent encrypted, and the decryption
key never travels.
