Cryptography simple definition
WebIn cryptography, a key is a piece of information used for scrambling data so that it appears random; often it's a large number, or string of numbers and letters. When unencrypted data, also called plaintext, is put into a cryptographic algorithm using the key, the plaintext comes out the other side as random-looking data. WebPublic-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. [1] [2] Key pairs are generated with cryptographic algorithms based on mathematical problems termed one-way functions.
