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. 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.

WebConfusion in a symmetric cipher is obscuring the local correlation between the input ( plaintext) and output ( ciphertext) by varying the application of the key to the data, while diffusion is hiding the plaintext statistics by spreading it over a larger area of ciphertext.

WebJun 11, 2024 · Each stream requires a key and a nonce. The key forms the shared secret and should only be known to trusted parties. The nonce is not secret and is stored or sent along with the ciphertext. The purpose of the nonce is to make a random stream unique to protect gainst re-use attacks.
