<P> Public - key cryptography , or asymmetric cryptography , is any cryptographic system that uses pairs of keys : public keys which may be disseminated widely , and private keys which are known only to the owner . This accomplishes two functions : authentication , where the public key verifies that a holder of the paired private key sent the message , and encryption , where only the paired private key holder can decrypt the message encrypted with the public key . </P>
