toolkit tso tawm (GNU Privacy Guard), tau tshaj OpenPGP cov qauv () thiab S/MIME, thiab muab cov khoom siv hluav taws xob rau cov ntaub ntawv encryption, ua haujlwm nrog hluav taws xob kos npe, kev tswj hwm qhov tseem ceeb thiab kev nkag mus rau cov khw muag khoom tseem ceeb rau pej xeem. Nco qab tias GnuPG 2.2 ceg tau muab tso rau hauv kev txhim kho kev tso tawm uas cov yam ntxwv tshiab txuas ntxiv ntxiv; tsuas yog kev kho kom raug tso cai hauv 2.1 ceg.
Qhov teeb meem tshiab tawm tswv yim ntsuas los tawm tsam , ua rau GnuPG dai thiab tsis tuaj yeem ua haujlwm txuas ntxiv mus txog thaum daim ntawv pov thawj teeb meem raug tshem tawm ntawm lub khw hauv zos lossis lub khw muag ntawv pov thawj rov tsim dua raws li cov yuam sij pej xeem tau lees paub. Qhov kev tiv thaiv ntxiv yog raws li tsis quav ntsej tag nrho los ntawm lub neej ntawd tag nrho cov neeg thib peb cov npe digital ntawm daim ntawv pov thawj tau txais los ntawm cov chaw khaws cia tseem ceeb. Cia peb nco qab tias txhua tus neeg siv tuaj yeem ntxiv nws tus kheej kos npe digital rau daim ntawv pov thawj arbitrary rau lub chaw khaws cia tseem ceeb, uas yog siv los ntawm cov neeg tawm tsam los tsim ntau tus lej kos npe (ntau tshaj li ib puas txhiab) rau tus neeg raug tsim txom daim ntawv pov thawj, cov txheej txheem uas cuam ββtshuam kev ua haujlwm ib txwm ntawm GnuPG.
Tsis quav ntsej lwm tus neeg kos npe digital yog tswj hwm los ntawm "tus kheej-sigs-tsuas yog" kev xaiv, uas tsuas yog tso cai rau tus tsim tus kheej kos npe los thauj cov yuam sij. Txhawm rau rov ua tus cwj pwm qub, koj tuaj yeem ntxiv "keyserver-xaiv tsis muaj tus kheej-sigs-tsuas yog, tsis muaj-ntshuam-huv" teeb tsa rau gpg.conf. Tsis tas li ntawd, yog tias thaum lub sijhawm ua haujlwm kev ntshuam ntawm ntau cov blocks raug kuaj pom, uas yuav ua rau cov dej ntws ntawm cov chaw cia hauv zos (pubring.kbx), es tsis txhob tso saib qhov yuam kev, GnuPG cia li tig rau hom tsis quav ntsej cov kos npe digital (βtus kheej-sigs -tsuas yog, import-huv").
Txhawm rau hloov cov yuam sij siv lub tshuab (WKD) Ntxiv qhov "--locate-external-key" kev xaiv uas tuaj yeem siv los tsim cov ntawv pov thawj hauv khw raws li cov yuam sij pej xeem tau lees paub. Thaum ua haujlwm "--auto-key-retrieve", WKD mechanism yog tam sim no nyiam tshaj cov servers tseem ceeb. Lub ntsiab lus ntawm WKD yog muab cov yuam sij rau pej xeem hauv lub vev xaib nrog qhov txuas mus rau lub npe sau npe hauv qhov chaw xa ntawv. Piv txwv li, rau qhov chaw nyob "[email tiv thaiv]"Tus yuam sij tuaj yeem rub tawm ntawm qhov txuas "https://example.com/.well-known/openpgpkey/hu/183d7d5ab73cfceece9a5594e6039d5a".
