Digitally signing a message ensures that the message originated from the stated sender. Encrypting ensures that the message has not been read or altered during transmission. To encrypt messages, you can use the public-key cryptographic system.
In this system, each participant has two separate keys: a public encryption key and a private decryption key. When someone wants send you an encrypted message, he or she uses your public key to generate the encryption algorithm. When you receive the message, you must use your private key to decrypt it.

The random key can then be used to decrypt the encoded message. This would work for messages sent to a single recipient, but it would be too cumbersome for those sent to multiple people. The most efficient way to distribute a message to several people is to encrypt the message using the random key.
This is because no public or private keys have been involved at that point, making the encryption on the message person-agnostic. All of the encrypted keys are then sent with the message. Each recipient can decrypt the copy of the random key that was encrypted using their public key, and then use the random key to decrypt the message.
