WebDec 16, 2024 · In public key cryptography, it’s much the same way: there are two keys — one that can encrypt the data and the other that can decrypt it. These keys are separate yet mathematically related to each other. That’s because they’re generated using an asymmetric algorithm that binds the public key to the private one. WebPublic key cryptography revolves around a couple of key concepts. The sections below explain these briefly. Asymmetric Cryptography - Algorithms. As with any encryption scheme, public key authentication is based on an algorithm. There are several well-researched, secure, and trustworthy algorithms out there - the most common being the …
