Question: WEP Key - What Are WEP Keys?
stands for Wired Equivalent Privacy, a standard for WiFi
wireless network security. But what exactly are WEP keys?
A WEP key
is a security code used on some Wi-Fi networks. WEP keys allow a group of devices on a local network (such as a home network) to exchange encoded messages with each other while hiding the contents of the messages from easy viewing by outsiders.
A WEP key is a sequence of hexadecimal digits. These digits include the numbers 0-9 and the letters A-F. Some examples of WEP keys are:
WEP keys are chosen by a network administrator. WEP keys are set on Wi-Fi routers, adapters and other wireless network devices. Matching WEP keys must be set on each device for them to communicate with each other.
The length of a WEP key depends on the type of WEP security (called "encryption") utilized:
- 40- / 64-bit WEP: 10 digit key
- 104- / 128-bit WEP: 26 digit key
- 256-bit WEP: 58 digit key
To assist with the process of creating correct WEP keys, some brands of wireless network equipment automatically generates WEP keys from ordinary text called a passphrase
. Some Web sites also offer automatic WEP key generators.
