Cryptography is dependent on both of these methods. Data encryption is the method of undoing the work done by encrypting data so that it can be read again. Crypto means hidden and graph means writing.Įncryption is a fundamental component of cryptography, as it jumbles up data using various algorithms. It is used to safeguard company secrets, secure classified information, and sensitive information from fraudulent activity, among other things. With the advancement of modern data security, we can now change our data such that only the intended recipient can understand it.Ĭryptography allows for the secure transmission of digital data between willing parties. The ciphertext should be known by both the sender and the recipient. Cryptography is the study of encrypting and decrypting data to prevent unauthorized access. ![]()
