Encryption in Cryptography:


Algorithms are the basis of cryptography. Encryption, a type of cryptography, refers to the mechanism of scrambling information so it cannot be deciphered or read by an unauthorized observer. An algorithm is a procedure for taking the original message, called plaintext, and using instructions combined with a message key to create a scrambled message, referred to as ciphertext. A cryptographic key is a piece of data used to encrypt plaintext to ciphertext, or ciphertext to plaintext, or both. Crypto is of Greek origin of the word kruptos, which means hidden. The end goal of cryptography is to conceal information so that only the intended recipients can “unhide” it. This concealing of information is called encryption, and when the information is unhidden, it is called decryption. There are two different subclasses of algorithms: block ciphers and stream ciphers. Block ciphers process “blocks” or chunks of text in a series.

Encryption: Encryption is a form of cryptography that “scrambles” plain text into unintelligible ciphertext.
