Digital signatures use symmetric key cryptography. With asymmetric key cryptography, there are two mathematically related keys. If a message is encrypted with one key, only the other key can decrypt it. For Sheila to receive a secret message from Albert, she needs a pair of keys. A computer program can generate these keys for her. Sheila can send Albert one key and keep the other key herself. Alternatively, she can put a key in a public place for him to retrieve on his own. It does not matter if someone else gets a copy of the public key. Albert uses the public key to encrypt his message, sending the ciphertext to Sheila. Only Sheila can decrypt the message because only she has the matching private key.
