COMPUTER FUNDAMENTALS

Detailed explanation-1: -Cryptography 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).

Detailed explanation-2: -There are five primary functions of cryptography: Privacy/confidentiality: Ensuring that no one can read the message except the intended receiver. Authentication: The process of proving one’s identity. Integrity: Assuring the receiver that the received message has not been altered in any way from the original.

Detailed explanation-3: -Public key encryption, also referred to as public key cryptography or asymmetric cryptography, is a process of encrypting and decrypting messages transferred over the network using two keys. This is the opposite of symmetric cryptography, where a single key is used for encryption and decryption.

Detailed explanation-4: -The “crypto” in the word “cryptocurrency” means “secret” in Greek – which gives you a clue as to what the field of cryptography is all about. Cryptography is the study and practice of sending secure, encrypted messages or data between two or more parties.
