Ukuvuselelwa kwezitifiketi ze-OpenVPN: letha isitifiketi, hhayi isibali sikhathi

Amadizayini amabili okuvuselela abukeka efanayo ekubuyekezweni kwedizayini futhi aziphatha ngendlela ehluke ngokuphelele ngoJanuwari. Owokuqala ugijimisa isibali sikhathi, ukhipha izitifiketi kabusha futhi uwisa amafayela kufolda eyabiwe. Owesibili uthatha ukuvuselela njengenkinga yokuletha: ubani ocela, yini eqinisekisa ukufaneleka, ingena kanjani into kudivayisi futhi yini eyenza iklayenti iyisebenzise. Owesibili kuphela ophila ngaphansi kwekhompyutha ephathekayo engena-inthanethi, impahla eseyekisiwe kanye nokulethwa okwehluleka buthule.

Qhathanisa amadizayini amabili lapho ehluka khona ngempela

Idizayini yesibali sikhathi ithuthukisa uhlangothi lweseva. Umsebenzi ohleliwe ubiza i-CA, kuvela isitifiketi esisha futhi umqhubi ubona umsebenzi usuqediwe. Konke okwenzeka ngemva kokukhishwa kuyinkinga yomunye umuntu, kuze kube yilapho idivayisi ihluleka ukuxhuma futhi usuku lokuphelelwa sichaza ukuthi kungani.

Idizayini yokugeleza komsebenzi ithuthukisa imayela lokugcina. Ithatha ukuthi ukukhishwa kuyisixhumanisi esisodwa ochungechungeni nokuthi isinyathelo ngasinye esilandelayo singehluleka ngokuzimela. Lokhu kubiza kakhulu ukwakha futhi kushibhe kakhulu ukuphatha, ngoba ukwehluleka kuvela njengezimo ezilandelwayo hhayi njengamaklayenti aphelelwe yisikhathi.

Indlela ewusizo yokugcina umehluko emehlweni ukulandelana okumele idizayini ngayinye ikubize ngokusobala.

detect window -> authenticate request -> authorize -> issue
-> deliver and stage -> activate -> verify fresh auth -> retire old material

Thola iwindi kusitifiketi uqobo

Funda ukusebenza kusitifiketi iklayenti esikwethulayo ngempela, hhayi kusukela osukwini olufakwe egameni lefayela elikopishiwe. Amagama amafayela ayashintsha, futhi ifayela elithi 2026 lingaba nesitifiketi esiphelelwa ngoMashi.

Shiya isikhala ewidini ngezimo ezihamba kancane: amadivayisi angena-inthanethi amasonto, izimvume ezidinga umuntu kanye nezindlela zokuletha ezihluleka kanye ngaphambi kokusebenza. Isibali sikhathi esibika impumelelo siqinisekisa kuphela ukuthi isibali sikhathi sagijima, hhayi okunye.

Gunyaza isicelo ngaphambi kokukhishwa kwanoma yini

Isitifiketi esikhona singaba yingxenye yendlela yokuvuselela esemthethweni, kodwa umbhalo waso wengqikithi awusona isinqumo sokugunyaza. Umbuzo okumele uphendulwe ukuthi ingabe le akhawunti nale divayisi kusenelungelo lokuba nobunikazi embuthweni, futhi leyo mpendulo ihlala emarekhodini akho empahla, hhayi kusitifiketi.

Ikhompyutha ephathekayo eseyekisiwe umsebenzi wayo ohleliwe osagijima akumele ithole ilungelo elisha. RFC 7030 kufanele kufundwe lapha ngoba kuhlukanisa ukubhaliswa kabusha okuqinisekisiwe ekugunyazeni nasekuqondiseni kweseva; kuyisibonelo sokubolekwa, hhayi isimangalo sokuthi i-OpenVPN noma i-EasyRSA ihlinzeka ngaleyo protokholi.

Ukuletha, ukulungiselela nokusebenzisa njengezinyathelo ezihlukene

Ukukhishwa kugcina ubunikazi, inhloso kanye nobudlelwano bokukhishwa, futhi okunye okwenziwe ngepheya elisha lokhiye akusizi uma ukhioye ohambelana nakho kungahambi kanye nakho. Letha ipheya ngomzila onedizayini yokulawula ukufinyelela ngemuva kwawo, ngoba i-URL engaqageliyo iwukufihla, hhayi ukulawula.

Ukulungiselela yindawo lapho iningi lokusebenza okuzenzakalelayo liphuka buthule. Iphrofayela engenisiwe ingahlala endaweni eyodwa ngesikhathi umphathi ebusisa ifayela kwenye indawo, futhi iklayenti liqhubeka nokwethula isitifiketi esidala kuze kube umuntu uyabona. Bhala indlela efundwa yiklayenti, i-akhawunti evunyelwe ukubhala kuyo kanye nomcimbi obangela ukulayisha kabusha. Bese uqinisekisa ukuthi okungena esikhundleni ifayela elisetshenziswa ngempela, hhayi ikhophi efike eceleni kwalo.

Ukuqinisekisa kusho ukuqinisekisa okusha ngempahla entsha kanye nokuhlola uhlelo lokusebenza oludingwa umsebenzisi. Ithubhu eselivele limisiwe lingase lisabonisa isitifiketi sangaphambili, ngakho ukuxhumana okuvuliwe akusona ubufakazi bokuvuselela okuphumelelayo.

Dizayina kuqala ukubuyiselwa kwewindi eliphuthelwe

Lapho ikhompyutha ephathekayo ifinyelela isevisi yokubhalisa kuphela nge-VPN, ukuphelelwa kwesikhathi kwakha umjikelezo: idivayisi idinga isitifiketi ukuze ingene ethubhuni futhi ithubhu lidinga ukuthola isitifiketi. Nquma ngohlelo lwangaphandle ngaphambi kokuba umsebenzi wokuqala ohleliwe uphume, kungaba yindawo yokubhalisa eqinisekisiwe ehlukile noma ukubhalisa kabusha okusizwa umphathi.

Noma yini oyikhethayo, kumele iqinisekise ocela kanye nelungelo lamanje. Ukuhlela iseva ukuthi yamukele izitifiketi eziphelelwe yisikhathi kunoma ubani ocela akusiyo indlela yokubuyisela, kuwukunciphisa okungapheli kokuhlola okuvikele ngayo ngenye ingxenye yedizayini.

Ekugcineni, gcina ukuvuselela nokuhlaselwa kuzinqubo ezihlukene. Ukhiye ophumile udinga ukuhoxiswa kanye nokusabela kumaseshini asebenzayo, futhi ukwandisa usuku lokuphelelwa akukho lutho kwalokho. Fakela idivayisi engena-inthanethi, ukulethwa okwehlulekile kanye nempahla eseyekisiwe esivivinyweni sokwamukela, futhi uhlelo lusilungele ukunika amandla.
