2. Each user places one of the two keys in a public register or other accessible file. This is the public key. The companion key is kept private.
3. If UserA wishes to send a confidential message to UserB, UserA encrypts the message using UserB's public key.
4. When UserB receives the message, she decrypts it using her private key.
