cryptographic algorithm uses a Secret Word to encrypt messages. You invent the Secret Word and deliver it to the recipient using a phone, text message, instant message, smoke signals, homing pigeon, or as a last resort... another email. When the encrypted message is received, it is destroyed from Lockbin's database, and decrypted in the recipient's browser, provided that they entered the Secret Word correctly.
