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 process of converting between readable text, called plaintext, and an unreadable form, called ciphertext. This occurs as follows: The sender converts the plaintext message to ciphertext. part of the process is called encryption(sometimes encipherment). The ciphertext is transmitted to the receiver.
