You use encryption to ensure that information is hidden from anyone for whom it is not cipher image to its original plain image is called decryption. Figure 1.1 illustrates this.

It can be used to encrypt data‚ create digital signatures‚ and help authenticating using Secure Shell and to provide a framework for public key cryptography. It includes an advanced key management facility and is compliant with the OpenPGP and S/MIME standards. Gpg4win is GNU Privacy Guard for Windows and Kleopatra is the certificate

its architecture. In order to examine the WLAN security threats‚ this paper will look at Denial of Service‚ Spoofing‚ and Eavesdropping. The paper will then explain how Wired Equivalent Privacy (WEP) works‚ which is the IEEE 802.11b/WiFi standard encryption for wireless networking. The discussion of WEP continues by examining its weaknesses‚ which result in it being much less secured than what was originally intended. This situation leads to further research regarding practical solutions in implementing
