Protecting The Wi-Fi Network From WPA Hack

Protecting The Wi-Fi Network From WPA Hack

The WEP encryption standard has been broken by the researcher Erik Tews after a year. He had recommended a switch to the WPA which is extra safe Protection for the Wi-Fi Network. He and his colleague Martin Back have discovered the method for cracking the WPA encryption standard in parts which is nothing but the Temporary Key Integrity Protocol (TKIP). The TKIP is mainly used to save the data safely on lots of wireless networks.

They are able to carry out their activities it within a time period of just 12 to 15 minutes.  Nevertheless, they have failed to learn about how to obtain access to the information that transmits in between the router and computer. Thus the WPA at present is quite safe to utilize as the typical Wi-Fi security.

However, it has been strongly recommended you to care for your router to protect it from WPA hack. You can keep it away from WPA hack in many different ways. One of the ways is to log in to router and then turn off the TKIP as an encryption type, and next only select to utilize Advanced Encryption System (AES), or the much tougher WPA2.

You can cut down the timing of the Temporary Key Integrity Protocol within the routers, with the intention that keys get refreshed in every two minutes or less. The quick revive creates it harder, although not completely unattainable for hackers to gain access.

Add Encrypt Or Decrypt Option In Context Menu

Add Encrypt Or Decrypt Option In Context Menu

Have you ever thought how could you encrypt or decrypt files and folders easily without following the tedious process? Yes, you can encrypt or decrypt files instantly by simply right clicking on the files and choosing the options of decrypts or encrypts files from the context menu.

    “EncryptionContextMenu”=dword:00000001
  • While copying and pasting this string, do take care of contents. Usually copied contents contains two quotes “” that will not be verified in registry file check so you need to delete and retype it manually.
  • Now save the file namely, “Encrypt.reg” and Save AS “All Files”. It means Save file one time  then Click on Save as option and enter name “All Files”
  • By double clicking on registry file you will be directly prompt to proceed with UAC prompt so you just click on OK to confirm that you wish to proceed further.

On receiving the email, the recipient needs to provide the decryption password to view the received message. The decryption password is to be sent by the sender itself. Secrets operate using the DES algorithm for encryption. The keys of this algorithm are by default set at 64bits. Other than the DES algorithm it also provides algorithms like Triple DES, AES Rijndael, Blowfish and ArcFour. The default keys of these algorithms are set at 128bits, 256bits, 448bits and 2048bits respectively.

The user has the liberty to choose any of these algorithms and ensure safe and secure message sending.
