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.
