WebFeb 6, 2024 · Cryptography involves creating written or generated codes that allow information to be kept secret. Cryptography converts data into a format that is unreadable for an unauthorized user, allowing it to be transmitted without unauthorized entities decoding it back into a readable format, thus compromising the data. Advertisements 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. green forest flower shopWebRSA is a type of asymmetric encryption, which uses two different but linked keys.
