WebA public-key cryptosystem is one in which messages encrypted with one key can only be decrypted with a second key, and vice versa. A strong public-key system is one in which possession of both the algorithm and the one key gives no useful information about the other key and thus no clues as to how to decrypt the message. WebA cryptographic system is any computer system that involves cryptography. Such systems include for instance, a system for secure electronic mail which might include methods for digital signatures, cryptographic hash functions, key management techniques, and so on.
