WebMost other key types are designed to last for long crypto-periods from about one to two years. When a shorter crypto-period is designed different key types may be used, such as Data Encryption keys, Symmetric Authentication keys, Private Key-Transport keys, Key-Wrapping keys, Authorization keys or RNG keys. WebCryptography is just a field where we are talking about coding, decoding of messages. It is basically communicating with your team mates without letting a detective know (or somebody from the other team). It talks about how you can make your messages more and more strong i.e., more secret. ( 1 vote) dailymotion rainforest talent show
