Saxeexinta iyo sirintu waxay ku dhawaad ​​noqdeen hawl maalmeedka isticmaalayaasha qaarkood. Iyadoo sirtu ay ka dhigayso faylkaaga mid aan loo akhriyin isticmaalayaasha aan la ogalayn, saxiixa ayaa kaa caawinaysa sheegashada iyo xaqiijinta daacadnimada faylka. Qalab badan ayaa diyaar ah oo ku habboon hawshan. Laakin waa maxay hababka iyo dhaqamada ugu wanagsan ee la raaco marka la saxeexayo ama la siraynayo faylkaaga? Waa maxay heerka ugu wanaagsan warshadaha la aqbalay? Maqaalkan, waxaan ku soo daboolnay qalab la yiraahdo Kleopatra kaas oo kuu ogolaanaya inaad sirayso ama saxiixdo faylashaada adigoo isticmaalaya heerarka OpenPGP .

Waa maxay OpenPGP

OpenPGP waa hab-maamuus markii hore loogu talagalay in lagu sireeyo isgaarsiinta sida iimaylka. Hab-maamuuska/Heerkan ayaa qeexaya farsamooyinka, hababka, iyo qaababka xogta iyo shahaadooyinka sir ah. GnuPG waa hirgalinta il furan ee heerarka OpenPGP , waxayna kuu ogolaataa inaad saxiixdo oo aad sirayso faylashaada. Asal ahaan waa aaladda khadka taliska oo ay yara adag tahay in la isla qabsado. Qalabka aan maanta ka hadli doono, Kleopatra waa fulinta GUI ee GnuPG.

Qalabku waa maamulaha shahaado iyo GUI ee GnuPG . Waxay kuu ogolaanaysaa inaad abuurto shahaadooyin, saxiix oo aad sirayso faylashaada adigoo dhawr dhagsi ah. Marka la eego awooddeeda, qalabku aad buu u fudud yahay in la isticmaalo oo la fahmo. Waxay qarisaa dhammaan caqabadaha ku lug leh hawlgallada sida saxiixa iyo sirta.

Kahor intaadan samayn wax saxiix ah iyo sireed, waxaad u baahan tahay inaad abuurto shahaadadaada ama lamaanaha muhiimka ah. Waxaad si fudud u garaaci kartaa Ctrl+N si aad u abuurto lamaane fure cusub, ama waxaad soo dejisan kartaa faylalka shahaadooyinka jira haddii ay jiraan. Barnaamijku wuxuu taageeraa ku dhawaad ​​dhammaan qaababka shahaado.

Haddii aad abuurayso lamaane cusub oo fure ah, Kleopatra ayaa ka dhigi doonta mid aad u fudud oo toos ah Wizardkeeda Hal-abuurka Lammaanaha Furaha ah. ^{(Key Pair Creation Wizard. )}Tallaabada ugu horreysa, waxaad dooran kartaa inaad rabto inaad abuurto furaha OpenPGP^(OpenPGP) ama furaha X.509. Markaa waxaad si ikhtiyaari ah geli kartaa magacaaga iyo iimaylkaaga tallaabada xigta. Iyadoo inta badan isticmaalayaasha laga yaabo inay ka gudbaan tallaabada xigta halkan laakiin qalabku wuxuu sidoo kale ku siinayaa qaar ka mid ah goobaha horumarsan.

Waxaad go'aansan kartaa algorithm-ka sireed oo aad qeexi kartaa xaaladaha shahaadadan loo isticmaali doono. Ugu dambayntii, waxa kale oo aad samayn kartaa shahaado shaqaynaysa oo kaliya ilaa muddo cayiman. Tallaabada ugu dambeysa, waxaad geli kartaa eraygaaga sirta ah, hubi inaad tan xasuusato maadaama aan laguu oggolaan doonin inaad sameyso wax hawlgallo ah oo ku saabsan shahaadadan la'aanteed sirta.

Saxeexa iyo sirta

Markaa taasi waxay ku saabsanayd soo saarista lamaanahaaga muhiimka ah ama shahaadadaada. Hadda waa waqtigii aad saxeexi lahayd ama aad sidi lahayd faylashaada. Kleopatra ayaa ka dhigaysa mid aad u fudud in taas la sameeyo isaga oo soo bandhigaya liiska macnaha guud ee midig-guji. Markaa, waxaad xaq u guji kartaa fayl kasta oo dooro ' Saxiix oo sir^{(Sign and encrypt)} ' Ama haddii aad rabto inaad saxiixdo oo aad ka gudubto sirta, waxaad riixi kartaa Xulasho badan oo GpgEX^{(More GpgEX Options)} ah oo dooro ikhtiyaar ku habboon.

Waxaad sidoo kale ka qarin kartaa ama ka saxeexi kartaa faylashaada codsiga ugu muhiimsan. Waxaad saxiixi kartaa fayl adigoo isticmaalaya mid ka mid ah shahaadooyinkii aad hore u abuurtay ama soo dejisay. Ka dib marka saxiixu dhammeeyo, faylka .sig ayaa lagu abuuri doonaa isla hagaha. Waxaana faylkan loo isticmaali karaa in lagu ansixiyo daacadnimada faylka aad saxiixday. Haddii faylka wax laga beddelay ka dib markaad saxiixday, faylka .sig wuxuu ku tusi doonaa saxeex aan sax ahayn.

Kleopatra waa qalab aad u fiican oo lagu maareeyo saxiixa faylka iyo sirta Waxay faa'iido u leedahay kiisas badan oo tijaabo ah waxayna kaa caawin kartaa inaad sugto faylashaada iyo macluumaadkaaga. Waxay adeegsataa qaar ka mid ah heerarka ugu fiican ee hoos yimaada, GUI -guna wuxuu ka dhigayaa mid aad u fudud in wax laga qabto hawlgalladan adag.

Sign and Encrypt files using OpenPGP certificates with Kleopatra.

Signing and encryption havе almost become a dаy to day tаsk of some users. While encryption makes your file unreadable to unаuthorіzed users, signing helps yоυ in claiming and verifуing the integrity of a file. A plethora of tоols are available that are suited to this task. But what іs the best ways and best practices to follow while signing or enсrypting уour file? What is the best industry accepted standards? In this post, we’ve covered a tool callеd Kleopatra that lets you encrypt or sign your files using the OpenPGP standards.

What is OpenPGP

OpenPGP is a protocol which was originally meant for encrypting communications such as emails. This protocol/standard defines techniques, methods, and formats of encrypted data and certificates. GnuPG is an open source implementation of OpenPGP standards, and it allows you to sign and encrypt your files. It is basically a command line tool and a little difficult to get along. The tool that we are going to talk about today, Kleopatra is a GUI implementation of GnuPG.

Sign & Encrypt files using  Kleopatra

The tool is a certificate manager and a GUI for GnuPG. It allows you to create certificates, sign and encrypt your files with just a few clicks. Given its capabilities, the tool is quite simple to use and understand. It hides all the complexities involved in operations such as signing and encryption.

Before performing any signing and encryption, you need to create your own certificate or key pair. You can simply hit Ctrl+N to create a new key pair, or you may import existing certificate files if any available. The program supports almost all certificate formats.

If you are creating a new key pair, Kleopatra will make it very simple and straightforward with its Key Pair Creation Wizard. In the first step, you can choose whether you want to create an OpenPGP or an X.509 key. Then you can optionally enter your name and email in the next step. While most of the users might go the next step from here but the tool also provides you with some advanced settings.

You can decide the encryption algorithm and specify in what cases will this certificate be used. Lastly, you can also create a certificate that is only valid until a certain period. In the last step, you can enter your passphrase, make sure you remember this as you will not be allowed to carry out any operations on this certificate without the passphrase.

Signing and Encryption

So that was about generating your key pair or your certificate. Now it is time to sign or encrypt your files. Kleopatra makes it very simple to do that by introducing a right-click context menu. So, you can right-click any file and select ‘Sign and encrypt’. Or if you just want to sign and skip encryption, you can click on More GpgEX Options and select a relevant option.

You can also encrypt or sign your files from the main application. You can sign a file using any of the certificates that you previously created or imported. After signing is complete, a .sig file will be created in the same directory. And this file can be used to validate the integrity of the file you signed. If the file were modified after you’ve signed it, the .sig file would show you an invalid signature.

Kleopatra is a great tool to manage file signing and encryption. It is useful in many test cases and can help you secure your files and information. It uses some of the best standards underneath, and the GUI makes it quite simple to deal with such complex operations. Click here to download Kleopatra.
