In a public-key cryptosystem,(71)encrypted with the public key can only be deciphered with the private key from the same(72). Conversely,(71)encrypted with the private key can be decrypted only with the public key. Users can make their public keys(73)available or place them at a key distribution center or others to access. However, the private key must be(74)safe. In public-key systems there's no(75)to find a safe channel for communicating a shared secret key.A.binarytextB.hypertextC.plaintextD.supertext
