Classification of Cryptographic Keys - Cryptomathic

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 … In cryptography, a key is a string of characters used within an encryptionalgorithm for altering data so that it appears random. Like a physical key, it locks (encrypts) data so that only someone with the right key can unlock (decrypt) it. The original data is known as the plaintext, and the data after the key encrypts it is … See more Before the advent of computers, ciphertext was often created by simply replacing one letter with another letter in the plaintext, a method known as a "substitution cipher." For instance, suppose that someone sends a message … See more Although the above examples of early cryptography illustrate how using a random string of information to turn plaintext into … See more There are two kinds of encryption: symmetric encryption and asymmetric encryption, also known as public key encryption.
