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
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. All you have to do is just add this option to context menu. Since decrypting or encrypting files could consume your more time, creating the shortcuts to this feature allows you instant access.
To enable decrypt or encrypt feature in Context Menu you have to follow given simple steps accurately. It is a process of registry hack.
- Launch Notebook
- Copy the below string and paste into notepad
- · [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
- 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.
- Finally, you are done.
Once you finished this process, you will be shown option to encrypt or decrypt files by clicking on any folder or files.
Secrets Help You Send Emails Securely
If you are accessing mails or sending emails using Wi-Fi in a public place, then you might be risking your privacy if your mails are not coded or encrypted. Whenever the user sends emails over a wireless or Wi-Fi network, it gives the hacker an opportunity to hack into your personal information or data. Public places provide convenience and not security.
Secrets provide you with the solution to the above mentioned problem. It is an online service which is absolutely free and allows the users to send mails in encrypted form. The only necessity or formality for using this service is to register with a valid Gmail account. After logging in to your account, click on the Compose button to compose a new email. After typing in the data or attaching files, the recipient field is to be filled, after its completion click on the “Encrypt and Send” command.
After successfully sending the email in encrypted form a pop rises up and asks for a decryption password. It is essential for the user to memorize this password as it will help you decrypt the email you have sent. It needs to be memorized because this password is not stored in the systems database.
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.
