In cryptography, encryption is the process of encoding information. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Ideally, only authorized parties can ... WebMar 16, 2024 · In cryptography, the objective of a cryptographic analysis isn’t always to decipher an encrypted text: sometimes, it’s more valuable, given some communication, to determine the secret key used to encrypt it. When this objective is achieved by leveraging the prior knowledge of some plaintext and perhaps of the ciphertext that derives from its … green county ky weather
