Yini umehluko phakathi kokusayina ngokobuchwepheshe nokokusayina kwe-electronically?

Ukusayina kwe-electronically yinoma iyiphi impawu yedijithiza ekhombisa imvume — ukusayina okukhanjiwe, igama nekheli elikanyiwe noma ukuchofoza ibhokisi lokulinga. Ukusayina ngokobuchwepheshe yinqubo yobuchwepheshe ethile esebenzisa i-cryptography ye-public key — i-satifiketi yedijithiza ne-private key — ukuxhumanisa ngokubuchwepheshe isici sabasayini nethizana elingashintshwanga.

Ingabe ukusayina ngokobuchwepheshe nge-dokk.ai kufanelekile ngokwezomthetho e-EU?

Yebo, ukusayina kwe-Advanced Electronic Signatures (AdES) okusayiniwe nge-satifiketi evumelekile evela kumhlinzeki wezinsizakalo ezikhonzekile ofakwe ehlelweni lokukhonzeka lezwe le-EU. Ukusayina kwe-Qualified Electronic Signatures (QES) kudinga i-satiifiketi efanelekile evela ku-QTSP — idokk.ai ihlinzeka inqubo yokusayina, kodwa ayikhuphuli izitifiketi.

Ngizothola kuphi i-satiifiketi yokusayina?

Izitifiketi zokusayina okufanelekile ngokwezomthetho zikhishwa Abahlinzeki Abafanelekile Bezinsizakalo Ezikhonzekile (QTSP). E-EU, izwe ngalinye elingunhlangothi lipapasha uhlu lokukhonzeka lwamazwe olwemukela abahlinzeki. Ekusetshenzisweni kwebhizinisi, xhumana ne-QTSP yesizwe. Izitifiketi zekilasi 1 ne-2 evela ku-CA yohwebo zifanelekile ukusetshenziswa okungasobala.

Ingabe i-private key yami iphephile lapho ngilayisha i-satiifiketi?

Ifayela le-satiifiketi yakho lilayishwa enkumbulweni ukusayina futhi lisalahlwa ngokushesha. Alibekwa noma kusiphi isikhali esiqinile, alibhalwa phansi futhi alidluliselwa ngaphandle kwenqubo yokusayina. Idokk.ai ayifinyeleli enqolobisweni ye-private key yakho ngaphandle kwesikhathi esikhulu senqubo yokusayina.

Yini izimpawu ezikhonzekile futhi zingathandazwa ngani?

Izimpawu ezikhonzekile ze-RFC 3161 zilandelela ngokubuchwepheshe usuku nesikhathi esicukile sokusayina, ezisayinwe igama lesithathu elingakhombi muntu. Lokhu kubonisa ukuthi ithizana lasayinwa ngaphambi kwesikhathi esithile — ngisho noma i-satiifiketi yomsayini kamuva yaphelela noma ikhishiwe.

Ingabe abantu abaningi bangasayina ithizana elifanayo?

Yebo. Isayini ngalinye ilayisha ithizana ne-satiifiketi yalo bese lisayina. Ukusayina okuningi kufakwa ku-PDF ngokulandelana. Iphethelo lokusayina ku-Acrobat Reader likhombisa bonke abafaka izimpawu nokulandelana kukusayina.

Kwenzekani uma ithizana lithintwa ngemuva kokusayina?

Ukusayina kuyaphelelwa. Noma yimuphi umfundi we-PDF ohlola ukusayina uzobonisa isixwayiso esibomvu 'ithizana lithintwe ngemuva kokusayina'. Le nkcindezetelo yokuchibiyela iyimpawu ebalulekile yokusayina ngokobuchwepheshe.

Yini i-LTV (ukuqinisekiswa kwesikhathi eside) futhi ingaselekiwa?

I-LTV ifaka ukuxhumana kwe-satiifiketi olwele, izimpendulo ze-OCSP kanye nedatha ye-CRL ngaphakathi kwe-PDF ngesikhathi sokusayina. Kusho ukuthi ukusayina kungaqinisekiswa ngesikhathi esizayo ngisho noma i-satiifiketi isiphelile ne-CA yayo isingekho. Idokk.ai isekela i-LTV ngokuzenzakalelayo.

Ngingasayina ifomu le-PDF eligcwalisiwe nge-Gcwalisa bese usayina?

Yebo. Inqubo elinconywa ukugcwalisa ifomu nge-Gcwalisa bese usayina, bese usebenzise ukusayina ngokobuchwepheshe okusekwe ku-satiifiketi nge-Sayina Ngokobuchwepheshe. Lokhu kuhlangamisa ukulula kokugcwalisa amafome nokwethenjwa kwezomthetho kokusayina okusekwe ku-satiifiketi.

Ingabe ithuluzi lisebenza nezitifiketi ezizikhulumela?

Yebo, kobuchwepheshe. I-satiifiketi ezikhulumela ikhiqiza ukusayina okusebenzayo kwe-cryptographic, kodwa i-Acrobat Reader izokhombisa isixwayiso esiphuzi ngoba i-satiifiketi ayiveli ku-CA ekhonzekile. Ukusayina okufanelekile ngokwezomthetho kudinga i-satiifiketi evela ku-CA noma ku-QTSP eyamukelekile.

Indlela yokusetshenziswa

1Layisha ithizana le-PDF odinga ukulisayina.
2Layisha ifayela le-satifiketi ye-PKCS#12 (.p12 noma .pfx) ufake iphasiwedi ye-satifiketi. I-private key isetshenziswa kula kwinkumbulo ukusayina futhi ayibekwa noma kunini.
3Lungiselela i-metadata yokusayina: isisusa sokusayina, indawo nokuthi kufanele kusetshenziselwe ukubonakala kukusayina esikhalweni.
4Chofoza Sayina ithizana. Ithuluzi lenza i-cryptographic hash ye-PDF, lisayine ne-satifiketi yakho futhi lifake ukusayina nezimpawu ezikhonzekile.
5Landa i-PDF esayiniwe. Vula ku-Acrobat Reader ukuqinisekisa ukuthi iphethelo lokusayina likhombisa uphawu oluluhlaza olwaqinisekisa ukusebenza kukusayina nokuthi ithizana alikashintshwa.

Emazwini amaningi ansuku zonke, ukusayina kwamandla kwanele. Kodwa ezimbonini ezilawulwa, izivumelwano zasezweni ezikwamanye amazwe, izifaki zehulumeni nanoma iyiphi ithizana lapho kumele ubonise ukuthi umuntu othile wasayina okuqukethwa okuthile ngesikhathi esithile, udinga ukusayina ngokobuchwepheshe kwe-cryptographic okusekwe ku-satifiketi. Ithuluzi le-dokk.ai lokusayina ngokobuchwepheshe lisebenzisa ukusayina ngokobuchwepheshe kwe-PKCS#7/CMS (PAdES) okusekwe ku-satifiketi kumafayela e-PDF. Uyalayisha ifayela lakho le-satifiketi ye-PKCS#12 (.p12 noma .pfx), ufake iphasiwedi ye-satifiketi, ulungiselele i-metadata yokusayina bese uchofoza Sayina. Ithuluzi lenza i-cryptographic hash ye-PDF, lisayine nge-private key yakho futhi lifake ukusayina ngezimpawu ze-RFC 3161 ezikhonzekile. Ngokuzenzakalelayo kufakwa izimpawu ezikhonzekile ze-RFC 3161, ezilandelela ngokubuchwepheshe usuku nesikhathi esicukile sokusayina ngagama lesithathu esingakhombi muntu. Lokho kusho ukuthi ukusebenza kukusayina kungaqinisekiswa ngesikhathi esizayo ngisho noma i-satifiketi yaphelela. Ukuqinisekiswa kwesikhathi eside (LTV) ithuluzi lifaka ukuxhumana kwe-satifiketi olwele, izimpendulo ze-OCSP kanye nedatha ye-CRL ku-PDF ngesikhathi sokusayina. Lokhu kuvumela ukuqinisekiswa kukusayina ngesikhathi esizayo ngisho noma i-satifiketi isiphelile ne-CA yayo isingekho. Abantu abaningi bangasayina ithizana elinye ngokulandela — isayini ngalinye ilayisha ithizana ne-satifiketi yalo. Ukusayina okuningi kufakwa ku-PDF ngokulandelana, futhi iphethelo lokusayina ku-Acrobat Reader likhombisa bonke abafaka izimpawu. Inqolobane ye-private key evela ku-satifiketi ethunyiwe icutshungulwa kula kwinkumbulo nje kuphela ukusayina bese isalahlwa ngokushesha. Ayibekwa noma kusiphi isikhali esiqinile, ayibhalwa phansi futhi ayithunywa ngaphandle kwenqubo yokusayina.

Imibuzo ebuzwa njalo

Ukuphepha nobumfihlo

Izinqolobane ze-private key ezivela ku-satifiketi ethunyiwe zicutshungulwa kula kwinkumbulo nje futhi azibhalwa ku-disk noma zibhalwe phansi. Amafayela e-satifiketi asuswa ngokushesha ngemuva kokusayina. I-PDF esayiniwe itholakala ukulayisha ihora elilodwa bese isuswa ngokuzenzakalelayo. Idokk.ai yona ngeke ifinyelele enqolobisweni ye-private key ngaphandle kwenqubo yokusayina.
