Different Types of Network Security Key

In this part, we will show you the different types of network security key. In general, there are three different types of network security keys which are WEP, WPA and WP2. In this section, we will introduce them one by one.


A WEP key is a security password for WiFi-enabled devices. WEP key lets devices on the Internet exchange encrypted messages with each other while preventing that from being easily encoded and read by outsides.

WEP is composed of numbers from 0 to 9 and the letters from A to F. According to the run WEP version, the required length of a WEP key could be 10, 26 or 58 characters long. The WEP network security key can be automatically generated for ease of use. If not, some websites will provide you the random network security key WEP which will be hard to guess.


WPA and WPA2 are more secure than WEP. The network security key – WPA comes with a password/passphrase that you can get from the network’s owner. If there is a router at home, you may see the WPA password on the side of it.

In general, with this kind of network, the owner can reset the WPA key as whatever the password or passphrase they want.


WPA2 is more secure than the WPA because it takes advantage of the AES algorithm, which is newer, faster and more advanced than previous.

WP2 is the recommended version for businesses, which tend to heightened security measures. But you need to keep in mind that using WPA2 needs hardware with higher processing power.
