The characteristics of this secret or key are determined by the system which uses it; some system designs require that such keys be in a particular format. It can be a Password like 'bret13i', a Passphrase like 'Idaho hung gear id gene', or a hexadecimal string like '65E4 E556 8622 EEE1'. The secret is used by all systems involved in the cryptographic processes used to secure the traffic between the systems (for example in WiFi encryption such as WEP or WPA ). Since one weakpoint of the Crypto System is the encryption algorithm's key, the Strength Of The Key is important, and since the strength of a key is in part dependent on its length, it is important to choose a key whose length is Cryptographically Secure (see Password Strength ). There are several tools available to help one choose a strong key. Diceware is one example. EXAMPLES
