WebFeb 1, 2024 · Encryption vs cryptography: Cryptography is the science of concealing messages with a secret code. Encryption is the way to encrypt and decrypt data. The first is about studying methods to keep a message secret between two parties (like symmetric and asymmetric keys), and the second is about the process itself.

WebWhy Cryptography is necessary in a Distributed System Supporting the facilities of a distributed system, such as resource distribution, requires the use of an underlying message passing system. Such systems are, in turn, reliant on the use of a physical transmission network, upon which the messages may physically be communicated between hosts. WebRSA algorithm (Rivest-Shamir-Adleman): RSA is a cryptosystem for public-key encryption , and is widely used for securing sensitive data, particularly when being sent over an insecure network such as the Internet .

"WebCryptography provides for secure communication in the presence of malicious third-parties—known as adversaries. Encryption uses an algorithm and a key to transform an input (i.e., plaintext) into an encrypted output (i.e., ciphertext). A given algorithm will always transform the same plaintext into the same ciphertext if the same key is used. " - Cryptography vs cryptosystem
