Ma^(Are) waxaad isku dayaysaa inaad ku furto qaar ka mid ah faylasha kombiyuutarkaaga kuwaas oo sir ah? Daaqadaha ayaa inta badan magacaabi doona faylal sir ah ama magacyo gal oo leh midabka cagaarka ah halkii ay ka ahaan lahaayeen qoraalka caadiga ah ee madow.

Note: If you are reading this post looking for information on decrypting files that were encrypted by CryptoLocker, this won’t help. You pretty much have to pay the ransom and hope they actually send you the encryption keys.

Marka la siraynayo faylasha iyo faylalka, Windows waxay isticmaali doontaa shahaado iskeed isu keentay oo ay ku jiraan furayaasha loo isticmaalo siraynta iyo siraynta xogta. Marka la furayo xogta sir ah marka la galiyo akoonka isticmaalaha ee soo saaray shahaadada, habka fur-furidku waa mid daah-furan oo faylasha si caadi ah ayaa loo furay.

Si kastaba ha ahaatee, haddii isticmaale kale ama nidaam isku dayo inuu galo isla faylashaas xogta ama haddii faylasha loo raro meel kale, markaa lama furi karo ilaa shahaadada asalka ah la rakibo.

Si kastaba ha ahaatee, hal shay oo ay tahay inaad xasuusato oo ku saabsan siraynta iyo furaha faylalka Windows^{(encrypting and decrypting files in Windows)} waa inaad had iyo jeer u baahan tahay shahaadooyinka/furayaasha sirta ah. Markaad sirayso fayl ama gal gudaha Windows , furayaasha sirta ah si toos ah ayaa loo abuuraa oo lala xidhiidhiyaa akoonkaaga isticmaale.

Gudaha Windows 7 iyo wixii ka sareeya, waxaad runtii heli doontaa degdeg ah oo ku weydiinaya inaad kaydiso furahaaga sirta ah ( shahaada EFS ).

Dhab ahaantii waa inaad tan isla markiiba sameyso. Hadii aanad haysan furayaashan sirta ah,ma awoodid inaad kala saarto xogta. Nasiib darro, ma jirto waddo arrintan ku wareegsan maadaama sirtu aad u xooggan tahay oo aan si fudud loo jabin karin.

Haddii aad weli geli karto kombuyuutarkii xogta markii hore lagu sidday, waxaad isku dayi kartaa inaad dhoofiso shahaadada ka dibna ku soo dejiso mishiin kale.

Kobcinta Shahaadooyinka EFS

Waxaa jira dhowr siyaabood oo lagu kaydiyo shahaadooyinka sirta faylka waxaanan ku sheegi doonaa hoos. Habka ugu horeeya waa in aad gujiso Start oo ku qor shahaadada^{(certificate)} .

Guji maamul shahaadooyinka isticmaalaha^{(Manage user certificates)} tani waxay u furi doontaa shahaadooyinka isticmaalaha hadda. Gudaha Windows 7 , waxaad sidoo kale ku qori kartaa certmgr.msc oo taabo Gelida^(Enter) si aad u furto khabiirka shahaadada.

Hadda balaadhi Personal ka dibna dhagsii Shahaadooyinka^{(Certificates)} . Waa inaad ku aragtaa dhammaan shahaadooyinka ku qoran shayga saxda ah. Waxaa laga yaabaa inay mid uun jirto, laakiin haddii aysan jirin, shahaadooyinka kaliya ee aad xiisaynayso waa kuwa haysta Nidaamka Faylka Sireeynta ee^{(Encrypting File System)} ku hoos qoran Ujeeddooyinka^{(Intended Purposes)} La damacsan yahay .

Midig ku dhufo^{(Right-click)} shahaadada, dooro Dhammaan Hawlaha^{(All Tasks)} ka dibna dhagsii Dhoofinta^(Export) .

Tani waxay furi doontaa Wizard Dhoofinta Shahaadada^{(Certificate Export Wizard)} , taas oo ah isla meesha aad gaari doonto haddii aad gujiso Back Up hadda (lagu talinayo)^{( Back up now (recommended))} marka ay ku dhaqaaqdo Windows.

Shaashada xigta, waxaad u baahan doontaa inaad doorato Haa, dhoofinta furaha gaarka ah^{(Yes, export the private key)} oo ay weheliso shahaadada. Haddii aadan haysan furaha gaarka ah, ma awoodi doontid inaad furto mid ka mid ah faylasha sir ah.

Shaashada xigta, waa inaad doorataa qaabka aad rabto inaad u dhoofiso shahaadada. Isweydaarsiga Macluumaadka Shakhsi ahaaneed^{(Personal Information Exchange)} waa in mar hore la doortaa oo waxaad kaga tagi kartaa kaliya sanduuqa ugu horreeya ee la saxo.

Maadaama shahaadadani ay ka kooban tahay fure gaar ah, waxaa lagaa rabaa inaad ku ilaaliso erayga sirta ah. Calaamadee sanduuqa sirta^(Password) ah oo ku qor erayga sirta ah ee adag.

Ugu dambeyntii, dhagsii Browse oo dooro goobta aad rabto inaad ku kaydiso faylka. Waxaa aad loogu talinayaa inaadan kaydin faylka kombayutarka laftiisa. Haddii ay wax ku dhacaan PC-ga, markaa waxaad luminaysaa furaha oo ay la socdaan.

Sidoo kale, sii faylkaaga magac adiga ku anfacaya, laakiin aan si fiican ugu muuqan dadka kale waxa uu yahay. Tusaale ahaan, ha magacaabin furaha EFS sidaan hoos ku sameeyay!

Guji soo socda ka dibna dhagsii dhame^(Finish) . Furahaaga sirta ah ee gaarka ah hadda waxa loo kaydiyay sidii fayl ahaan. Hadda waxaad qaadan kartaa faylkan oo aad ku soo dejisan kartaa mishiin kasta oo Windows ah. ^(Windows)Soo dejintu^(Importing) runtii way fududahay. Waxa kaliya oo ay tahay inaad sameyso waa laba-guji faylka oo wuxuu furi doonaa Wizard Import Shahaadada^{(Certificate Import Wizard)} .

Markaad soo dejiso shahaadada, waxaad awoodi doontaa inaad furto faylal kasta oo lagu sireeyay shahaadadaas. Sidii hore loo sheegay, haddii aad isku dayayso inaad furto faylal sir ah oo aadan haysan ama aadan heli karin shahaadada, markaa faylalkaas asal ahaan way baxeen.

Barnaamijyada qaarkood waxay sheegaan inay faylashaada ku dejin karaan qiimo aad u badan, laakiin weligood iimay shaqayn, waana sababta aanan midna halkan ugu soo qorin. Haddii aad wax su'aalo ah qabtid, xor ayaad u tahay inaad faallo ka bixiso. Ku raaxayso!

How to Decrypt Encrypted Windows Files

Are уou trying to open ѕome files on your computer that are encrypted? Windows will usually designate encrypted file or fоlder names with the color green instead of the normal black text.

Note: If you are reading this post looking for information on decrypting files that were encrypted by CryptoLocker, this won’t help. You pretty much have to pay the ransom and hope they actually send you the encryption keys.

When encrypting files and folders, Windows will use a self-generated certificate that contains keys used to encrypt and decrypt the data. When opening encrypted data when logged into the user account that generated the certificate, the decryption process is transparent and the files are opened normally.

However, if another user or system tries to access those same data files or if the files are moved to another location, then they cannot be opened unless the original certificate is installed.

In either case, one thing you have to remember about encrypting and decrypting files in Windows is that you always need the encryption certificates/keys. When you encrypt a file or folder in Windows, encryption keys are automatically created and associated with your user account.

In Windows 7 and higher, you’ll actually get a prompt asking you to backup your encryption key (EFS certificate).

You should definitely do this immediately. If you do not have these encryption keys, you will not be able to decrypt the data. Unfortunately, there is no way around this since the encryption is very strong and cannot be broken easily.

If you can still access the computer where the data was originally encrypted, you can try exporting the certificate and then importing it on a different machine.

Backing Up EFS Certificates

There are a couple of ways to backup file encryption certificates and I’ll mention them below. The first way is to click on Start and type in certificate.

Click on Manage user certificates and this will open up the certificates for the current user. In Windows 7, you can also type in certmgr.msc and press Enter to open the certificate manger.

Now expand Personal and then click on Certificates. You should see all the certificates listed in the right pane. There might only be one, but if not, the only certificates you are interested in are the ones that have Encrypting File System listed under Intended Purposes.

Right-click on the certificate, choose All Tasks and then click on Export.

This will open the Certificate Export Wizard, which is the same place you will reach if you click on Back up now (recommended) when prompted by Windows.

On the next screen, you will want to select Yes, export the private key along with the certificate. If you don’t have the private key, you won’t be able to decrypt any of the encrypted files.

On the next screen, you have to choose the format you want to use to export the certificate. Personal Information Exchange should already be selected and you can leave it with just the first box checked.

Since this certificate contains a private key, you are required to protect it using a password. Check the Password box and type in a strong password.

Finally, click Browse and choose a location where you want to save the file. It is highly recommended you do not save the file onto the computer itself. If something happens to the PC, then you lose the key along with it.

Also, give your file a name that is helpful for you, but not super obvious to others what it is. For example, don’t name it EFS key like I did below!

Click next and then click Finish. Your private encryption key is now saved as a file. You can now take this file and import it on any other Windows machine. Importing is really easy. All you have to do is double-click on the file and it will open up the Certificate Import Wizard.

Once you import the certificate, you will be able to decrypt any files that were encrypted with that certificate. As previously mentioned, if you are trying to open encrypted files and you don’t have or can’t find the certificate anymore, then those files are basically gone.

Some programs state they can decrypt your files for a hefty price, but they have never worked for me and that’s why I haven’t listed any of them here. If you have any questions, feel free to post a comment. Enjoy!
