Waxaan dhawaan iska diiwaan galiyay adeegga VPN ee isticmaalkayga gaarka ah si xidhiidhkayga internetka^(Internet) ee guriga uu gabi ahaanba u noqdo mid qarsoodi ah. Iyada oo dhan basaasiinta iyo muujinta jabsiga ayaa maalmahan socday, ma qabo in aan haysto wax yar oo ammaan dheeri ah oo dhinacayga ah haddii ay dhacdo. Markii aan ku rakibay software-ka kumbuyuutarka oo aan ku xiray VPN , waxay u muuqatay inay si fiican u shaqeyneyso inta aan sheegi karo.

Si kastaba ha ahaatee, anigoo ah qof farsamo yaqaan ah, ma aqbali karin oo kaliya in wax walba ay shaqeynayaan aniga oo aan si dhab ah u xaqiijin in qarsoodiga la kartiyeeyay. Markaa inkasta oo aanan ku ciyaarin baakidh wax quudiya iyo falanqeeyaha borotokoolka, haddana waan sii socday oo aan soo dejiyay utility network taasoo ii ogolaatay inaan dhab ahaantii arko xogta laga soo wareejinayo kombayutarkayga.

Waxaan hubiyay xiriirka markii aan lagu xirin VPN - ka waxaanan qabsaday baakado qaar ka dibna waxaan sameeyay wax la mid ah markii lagu xiray. Si fudud, waxaan awooday inaan arko in xogta la wareejinayo ay dhab ahaantii sir tahay markii loo dirayo VPN -ka . Maqaalkan, waxaan ku tusi doonaa sida aad u xaqiijin karto in sidoo kale la qarinayo xiriirkaaga.

Haddii aanad lahayn wax khibrad farsamo ah, runtii ha ka welwelin. Waxa kaliya ee aad u baahan tahay inaad sameyso waa inaad riixdo batoonka rikoodhka, dulmar liiska oo hubi qoraal. Waxaad iska indhatiri kartaa wax kasta oo kale maadaama ay inta badan noqon doonto mid xun ilaa aad wax ka taqaano kombayutarada iyo isku xidhka. Mac - ka waxaan ku isticmaali doonnaa CocoaPacketAnalyzer^{(CocoaPacketAnalyzer)} , kombuyutarkana waxaan ku isticmaali doonnaa Wireshark .

Ku xaqiiji sirta Mac

Marka hore, horay u soco oo soo dejiso CocoaPacketAnalyzer Mac gaaga oo socodsii. Waa inaad ku aragtaa shaashadda bilowga oo leh afar badhan oo waaweyn.

Qabashada waa waxa aad gujin doonto si aad u bilowdo qabashada taraafikada shabakada Haddii aad kaydiso fadhiga qabashada, waxa loo yaqaan faylka raadraaca oo aad furi kartaa kuwaas mar kale adigoo isticmaalaya badhanka labaad. Si kastaba ha ahaatee, ujeedooyinkayaga, waxaan kaliya rabnaa inaan aragno xogta oo sir ah oo runtii ma badbaadin doono mid ka mid ah qabashadaas.

Kahor intaanan samaynin qabashada, horay u soco oo guji Dookhyada^{(Preferences)} si aad u dejiso sida aan u qabsaneyno xogta. Guji ^(Click)Qabashada^(Capture) xagga sare iyo goobta kaliya ee aan u baahanahay inaan hubino halkan waa Qabashada Interface^{(Capture Interface)} .

Marka hore^(First) , hubi inaad riixdo badhanka Refresh yar oo ku yaal dhanka midig ee sanduuqa liiska. Markaad gujiso sanduuqa, waxaad arki doontaa dhawr doorasho, kuwaas oo dhamaantood u muuqda kuwo jahawareer leh. Kuwa kaliya ee aad u baahan doonto inaad ka doorato waa kuwa leh IPV4 oo ay ku taxan yihiin nambaro ka dib. Uma baahnid inaad doorato midka leh 127.0.0.1. Waxaad u baahan doontaa inaad doorato midka leh ciwaanka IP-ga ee xidhiidhka aad hadda isticmaalayso. Waxaad taas ku ogaan kartaa adiga oo aadaya Nidaamka Dookhyada^{(System Preferences)} ka dibna dhagsii Network .

Guji^(Click) xiriirka leh dhibicda cagaaran ee sanduuqa liiska ee bidix ka dibna calaamadee goobta ciwaanka IP-ga ee qaybta gacanta midig. Sida aad arki karto, waxay leedahay 192.168.1.x, si ay u dhigma en0 - IP4 - 192.168.1.68 ee liiska hoos u dhaca ee barnaamijka. Hadda horay u soco oo xidh daaqada Dookhyada Qabashada si aad ugu soo noqoto shaashadda weyn.

Horey u soco oo dhagsii Qabashada^(Capturing) oo hadda waxaad arki doontaa wada hadal cusub oo soo baxay halkaas oo aad ka dooran karto dhowr habayn ka dibna bilaabi karto qabashada.

Halkan uma baahnid inaad wax ka bedesho ujeedooyinkayaga, markaa si aad u bilowdo waxaad u baahan tahay oo kaliya inaad riixdo Start . Kahor intaadan samayn, si kastaba ha ahaatee, waxaa jira waxyaabo ay tahay in la xuso. Marka hore, waa inaad isku daydaa inaad xidho dhammaan barnaamijyada iyo barnaamijyada tabbarrada socda oo kaliya fur daaqadda biraawsarkaaga. Shabakadu^(Network) waxa ay qabataa tiro xog ah oo xataa dhawr ilbiriqsi waxay keeni doontaa in ka badan kumanaan saf oo xog ah. Markaa si ay u fududaato, xidh wax kasta oo dila inta ugu badan ee hababka asalka ah ee suurtogalka ah marka hore, ka dibna dhagsii Start .

Kadib markaad taas sameyso, isla markiiba ku shub hal ama laba goobood ka dibna dhagsii Jooji^(Stop) . Waxa kaliya oo aad doonaysaa in aad qabsato dhawr ilbiriqsi mana aha wax dheeraad ah. Xitaa waxaa laga yaabaa inay fikrad fiican tahay in cinwaannada shabakadda mar hore lagu qoray tab biraawsarkaaga ka dibna kaliya waxaad riixi kartaa Gelida^(Enter) si aad u shubto boggaga marka aad bilowdo qabashada.

Markaad taabo Jooji^(Stop) , waxaad arki doontaa daaqad sidan u eg:

Hadda tani waxay u ekaan kartaa gibberish buuxda, laakiin taasi way fiican tahay. Waxa kaliya ee aad u baahan tahay waa inaad dul marto liiska sare, kaas oo ah qaabka shaxda oo aad fiiriso xogta aad ku aragto sanduuqa midigta hoose, oo aan kor ku iftiimiyay. Hadda maadaama ay u badan tahay inay jiraan kumanaan saf, waxaad si degdeg ah u cadaadin kartaa fallaadha hoose oo aad fiirin kartaa isbeddelka xogta xagga hoose.

Haddii xiriirkaaga VPN uu dhab ahaantii qarsoodi yahay, sadar kasta oo aad dhex-gudbiso waa in ay muujisaa xogta u eg xogta sawirka kore. Maadaama ay tahay mid aan la akhrin karin oo ay tahay tiro xarfo ah oo random ah, waa la siray. Xidhiidh qarsoodi ah, waa in waxba loo akhriyi karin saf kasta dhammaan kumanaanka saf. Hadda aan ku tuso waxa aad ku arki doonto xidhiidhka aan qarsoodi ahayn, sida marka aanad ku xidhnayn VPN :

Sida aad kor ku arki karto, waxaan akhrin karaa waxyaabo badan oo badan hadda oo aysan jirin wax sir ah. Waxaan arkay inaan booqday aseemkishore.com anigoo isticmaalaya Mac iyo Safari iyo xog kale oo badan. Baakad kastaa ma noqon doonto mid tan lagu akhriyi karo xiriir aan qarsoodi ahayn, laakiin baakadaha badankood waxaad awoodi doontaa inaad aragto xogta dhabta ah, koodhka HTML , madaxa borotokoolka, iwm. Sidaan horay u soo sheegay, xiriir qarsoodi ah, xitaa xitaa hal baakidh. waxay noqon doontaa mid la fahmi karo.

Ka xaqiiji sirta kombayutarka

Habka lagu hubinayo PC-ga waa mid la mid ah sida aan kor ku muujiyey, marka laga reebo inaad isticmaalayso barnaamij kale oo la yiraahdo Wireshark . Markaad soo dejiso, billow oo shaashadda guriga waa inay u ekaataa sidan:

Sida Mac -ka, waxa ugu horreeya ee aad u baahan doonto inaad samayso waa inaad doorato interface-ka (interface network) oo aad rabto inaad xogta ku qabato. Guji^(Click) Liiska Interface-^{(Interface List)} ka oo waxaad arki doontaa liiska isku-xidhka shabakadaha. Waxaan jeclahay Wireshark in yar oo ka sii fiican taas oo aad si dhab ah u arki karto inta xogta lagu wareejinayo interface kasta, taas oo sahlaysa in la arko mid ka mid ah isku xirka aasaasiga ah.

Horey u soco oo calaamadee sanduuqa ku xiga interface interface ka dibna dhagsii xir^(Close) . Hadda waxa kaliya oo ay tahay inaad sameyso waa guji badhanka Start (hoos badhanka Liiska Interface^{(Interface List)} ) oo aad fiicnaan doontaa inaad tagto. Uma baahnid inaad doorato ama wax kale u badasho ujeedooyinkayaga. Markaad dhamaystirto qabashada, waa inaad aragto shaashad sidan oo kale ah:

Waxaa laga yaabaa inaad balaadhiso daaqadda shaashadda oo dhan ka dibna isku hagaajiso muraayadaha hoose iyo kuwa sare si waafaqsan, laakiin sida aad arki karto xogta ayaa ku jirta qaabka saxda ah ee CocoaPacketAnalyzer ee Mac . Guji^(Scroll) liiska ugu sarreeya oo hubi in qaybta xogta ay dhammaystiran tahay gibberish, taas oo macnaheedu yahay in xidhiidhkaagu yahay mid qarsoodi ah. Haddii aad awoodo inaad akhrido ereyo ama qoraal, waxay la macno tahay in xogta aan la sirin. Hubi in aad si degdeg ah uga dhex baadhayso ugu yaraan dhawr boqol oo saf addoo isticmaalaya furayaasha falaarta.

Waxaan rajeyneynaa in boostadani ay maskaxdaada dejin doonto markaad ogaato xiriirkaaga VPN inuu dhab ahaantii si ammaan ah u qarsoon yahay! Waan ogahay inay i dareensiisay fiicnaan badan. Haddii aad hayso wax su'aalo ah oo ku saabsan barnaamijyada ama aad dhib kala kulanto tarjumaada natiijooyinka, faallo ku dheji waxaan isku dayi doonaa inaan ku caawiyo. Ku raaxayso!

How to Check if Your VPN Connection is Actually Encrypted

І recently subscribed to a VPN service for my personal use so that my Internet сonnection from home is cоmpletely encrypted. With all the spying and hacking revelаtions going on thеѕe days, I don’t mind haνing a little bit of extra security on my side just in case. Once I had installed the software on computer and connected to the VPN, it ѕeemed to be working fine as fаr as I cоuld tell.

However, being a techie person myself, I couldn’t just accept that everything was working without actually verifying that the encryption was enabled. So even though I hadn’t played around with a packet sniffer and protocol analyzer, I went ahead and downloaded a network utility that let me actually see the data being transferred back and forth from my computer.

I checked the connection when not connected to the VPN and captured some packets and then did the same thing when connected. Easily, I was able to see that the data being transferred was actually encrypted when being sent to the VPN. In this article, I’ll show you how you can verify if your connection is encrypted also.

If you don’t have any technical expertise, don’t really worry. All you need to do is press a record button, scroll through a list and check some text. You can ignore everything else as it’ll mostly be gibberish unless you know something about computers and networking. On the Mac we’re going to use CocoaPacketAnalyzer and on the PC we’re going to use Wireshark.

Verify Encryption on a Mac

Firstly, go ahead and download CocoaPacketAnalyzer on your Mac and run it. You should see the startup screen with four large buttons.

Capturing is what you’ll click on to start a capture of network traffic. If you save a capture session, it’s called a trace file and you can open those again later on using the second button. However, for our purposes, we just want to see the data is encrypted and won’t really be saving any of these captures.

Before we perform a capture, go ahead and click on Preferences to set up how we are going to capture the data. Click on Capture at the top and the only setting we need to check here is Capture Interface.

First, be sure to press the little Refresh button that is located to the right of the list box. When you click on the box, you’ll see a couple of options, all of which look confusing as heck. The only ones you’ll need to choose from are the ones that have IPv4 listed with some numbers after it. You don’t need to pick the one that has 127.0.0.1. You’ll want to pick the one that has the IP address for the connection you’re currently using. You can figure this out by going to System Preferences and then clicking on Network.

Click on the connection that has the green dot in the list box on the left and then check the IP address field on the right-hand section. As you can see, it says 192.168.1.x, so that matches the en0 – IP4 – 192.168.1.68 option in the dropdown list in the program. Now go ahead and close the Capture Preferences window to get back to the main screen.

Go ahead and click on Capturing and you’ll now see a new dialog pop up where you can pick a few settings and then start the capture.

Here you don’t need to change anything for our purposes, so to get start you just need to press Start. Before you do, however, there are some things to note. Firstly, you should try to close all program and taskbar programs running and only keep your browser window open. Network captures record tons of data and even a few seconds will result in more than a thousands rows of data. So to keep it simple, close everything and kill as many background processes as possible first, then click Start.

After doing that, immediately load one or two sites and then click Stop. You only want to capture for a few seconds and nothing more. It might even be a good idea to have the web addresses already typed into tabs in your browser and then you can just press Enter to load the pages once you start the capture.

Once you press Stop, you will see a window that looks like this:

Now this may look like absolute gibberish, but that’s fine. All you need to do is scroll through the list at the top, which is in table format and look at the data you see in the box in the lower right, which I highlighted above. Now since there are probably thousands of rows, you can just keep pressing the down arrow key fast and looking at the data change at the bottom.

If your VPN connection is actually encrypted, every line you scroll through should show data that looks like the data in the above image. Since it’s unreadable and just a bunch of random characters, it’s encrypted. With an encrypted connection, nothing should be readable for any row in all those thousands of rows. Now let me show you what you’ll see on an unencrypted connection, such as when you’re not connected to a VPN:

As you can see above, I can read a whole lot more stuff now that there is no encryption. I see I visited aseemkishore.com using a Mac and Safari and lots of other data. Not every packet will be this readable on an unencrypted connection, but for most packets you’ll be able to see the actual data, HTML code, protocol headers, etc. As I mentioned before, on an encrypted connection, not even a single packet will be understandable.

Verify Encryption on a PC

The process for checking on a PC is pretty much the same as I have shown above, except that you are using a different program called Wireshark. Once you download it, start it up and the home screen should look like this:

Like on the Mac, the first thing you’ll need to do is pick the interface (network interface) that you want to capture the data for. Click on Interface List and you’ll see the list of network interfaces. I like Wireshark a little better in that you can actually see how much data is being transferred on each interface, which makes it easy to see which one is the primary connection.

Go ahead and check the box next to the appropriate interface and then click Close. Now all you have to do is click on the Start button (below the Interface List button) and you’ll be good to go. You don’t have to change any other options or anything else for our purposes. Once you complete a capture, you should see an screen like this:

You may have to expand the window full-screen and then adjust the bottom and top panes accordingly, but as you can see the data is in the exact same format as CocoaPacketAnalyzer on the Mac. Scroll through the list at the top and make sure that data section is complete gibberish, which means your connection is encrypted. If you’re able to read any words or text, it means the data is not being encrypted. Make sure you browse through at least a couple of hundred rows quickly using the arrow keys.

Hopefully this post will put your mind at ease once you know your VPN connection is actually securely encrypted! I know it made me feel a lot better. If you have any questions about the programs or are having trouble interpreting the results, post a comment and I’ll try to help. Enjoy!
