With the modernization of technology, cryptography got way more complex. There are three important tools in modern cryptography that form the basis for both TLS and DNSSEC: public key encryption, hashes, and signing. Before the modern era, cryptography focused on message confidentiality (i.e., encryption)conversion of messages from a comprehensible form into an incomprehensible one and back again at the other end, rendering it unreadable by interceptors or eavesdroppers without secret knowledge (namely the key needed for decryption of that message). .
