WebFeb 15, 2024 · As an essential aspect of modern data security, using cryptography allows the secure storage and transmission of data between willing parties. Here are a few terminologies which will help you understand what cryptography is, with better clarity. There are two primary aspects of cryptography, they are: 1. Encryption. WebCryptography is the study of securing communications from outside observers. Encryption algorithms take the original message, or plaintext, and converts it into ciphertext, which is not understandable. The key allows the user to decrypt the message, thus ensuring on they can read the message. flower soft polar white

WebCiphertext is encrypted text transformed from plaintext using an encryption algorithm. Ciphertext can't be read until it has been converted into plaintext (decrypted) with a key. The decryption cipher is an algorithm that transforms the ciphertext back into plaintext. WebElectronic Code Book (ECB) is a simple mode of operation with a block cipher that's mostly used with symmetric key encryption. It is a straightforward way of processing a series of sequentially listed message blocks. The input plaintext is broken into numerous blocks.
