Consider a keyring that contains a variety of keys. These keys might be various shapes and sizes, but one thing is certain, each will generally serve a separate purpose. One key might be used to start an automobile, while another might be used to open a safety deposit box. The automobile key will not work to open the safety deposit box and vice versa. This analogy provides some insight on how cryptographic key types work. These keys are categorized in respect to how they … WebJan 18, 2024 · Cryptographic keys are symmetric or asymmetric.
