Ichi chinyorwa chakanyorwa makore akati wandei apfuura, apo kuvharira mutumwa weTeregiramu kwakakurukurwa zvakanyanya munharaunda uye ine pfungwa dzangu panyaya iyi. Uye kunyange nhasi nyaya iyi inenge yakakanganwa, ndinovimba kuti zvichida icharamba ichifarira kune mumwe munhu
Ichi chinyorwa chakaonekwa semugumisiro wemafungiro angu pamusoro pechinyorwa chekuchengetedzwa kwedhijitari, uye ndakakahadzika kwenguva yakareba kana zvakakodzera kubudiswa. Neraki, kune nhamba huru yenyanzvi dzinonyatsonzwisisa matambudziko ese, uye ini handikwanise kuvaudza chero chinhu chitsva. Nekudaro, kunze kwavo, kune zvakare nhamba huru yevashambadziri uye mamwe mablogiki vasingangoite zvikanganiso ivo pachavo, asi zvakare vanopa huwandu hukuru hwengano nezvinyorwa zvavo.
Haisi chakavanzika kuti zvimwe zvakakomba zvishuwo zvanga zvichipisa mudhijitari yehondo nguva pfupi yadarika. Isu, hongu, tinoreva imwe yenyaya dzinokurukurwa zvakanyanya muRussia yemazuva ano, iyo kuvharika kweTeregiramu messenger.
Vanopikisa kuvharidzira vanopa izvi sekurwisana pakati pemunhu nehurumende, rusununguko rwekutaura uye kutonga kwakakwana pamunhu. Vatsigiri, pane zvinopesana, vanotungamirirwa nekufunga nezvekuchengetedzwa kwevanhu uye kurwisana nematsotsi nemagandanga.
Kutanga, ngatimbofungidzira kuti chaizvo mutumwa weTeregiramu anoshanda sei. Tinogona kuenda kupeji yavo yekumba toverenga nezve mabatiro avanoita. Imwe yemabhenefiti makuru ekushandisa iyi chaiyo mhinduro ichave iyo isingachinjiki kusimbisa kune yekupedzisira-mushandisi chengetedzo. Asi chii chaizvoizvo chinorehwa naikoku?
Sezvimwe mune mamwe akawanda masevhisi eruzhinji, data rako rinofambiswa mune encrypted fomu, asi chete kune epakati maseva, mavari mune yakavhurika fomu uye chero admin, kana achinyatsoda, anogona kuona nyore tsamba dzako dzese. Une kupokana kupi nokupi here? Wobva wafunga nezvekuti basa rekubatanidza pakati pemidziyo rinoitwa sei. Kana iyo data yakavanzika, inosvika sei kune yechitatu mudziyo? Mushure mezvose, iwe haupe chero akakosha makiyi emutengi e decryption.
Semuenzaniso, sezvinoitwa muProtonMail mail sevhisi, kwaunoshanda nesevhisi yaunoda kupa kiyi inochengetwa pamushini wako wepanzvimbo uye iyo inoshandiswa nebrowser kubvisa mameseji mubhokisi rako retsamba.
Asi hazvisi nyore kudaro. Pamusoro pekutaura nguva dzose, kune zvakare zvakavanzika. Pano tsamba dzinonyatsoitwa chete pakati pezvishandiso zviviri uye hapana kutaura kwechero kuwiriranisa. Iyi ficha inongowanikwa pamafoni evatengi, ane chat screenshots akakiyiwa padanho reapp uye chat yakaparadzwa mushure menguva yakatarwa. Padivi rehunyanzvi, iyo data ichiri kuyerera kuburikidza nepakati maseva, asi haina kuchengetwa ipapo. Uyezve, kuzviponesa hakuna zvazvinoreva, sezvo vatengi chete vane makiyi edecryption, uye encrypted traffic haina kunyanya kukosha.
Ichi chirongwa chinoshanda chero bedzi vatengi uye sevha vachichishandisa nekutendeseka uye chero bedzi pasina akasiyana marudzi ezvirongwa pachishandiso chinotumira snapshots zvechidzitiro chako kune vechitatu mapato pasina ruzivo rwako. Saka pamwe chikonzero chekusada kwakadai kweTeregiramu kune chikamu chevamiriri vemitemo chinofanira kutsvakwa muhurukuro dzakavanzika? Izvi, semaonero angu, ndiwo mudzi wekusanzwisisana kweruzhinji rwevanhu. Uye isu hatizokwanisa kunyatsonzwisisa chikonzero chekusanzwisisa uku kudzamara tanzwisisa kuti encryption chii muhuwandu uye kubva kunani kwainoitirwa kuchengetedza data rako.
Ngatimbofungidzira kuti munhu anorwisa anoda kutumira meseji yakavanzika kushamwari dzake. Saka zvakakosha zvekuti zvakakosha kunetsa uye kuitamba zvakachengeteka. Teregiramu isarudzo yakanaka kudaro kubva pakuona kwenyanzvi yekuchengetedza ruzivo? Kwete kwete. Ini ndinopokana kuti kushandisa chero yevanozivikanwa pakarepo vatumwa kune iyi ndiyo yakaipisisa sarudzo yaungasarudza.
Dambudziko guru nderekushandiswa kwehurongwa hwekutumira mameseji, uko tsamba yako ichatanga kutsvaga. Uye kunyangwe yakachengetedzwa zvakakwana, chokwadi chekuvapo kwayo chinogona kukanganisa iwe. Ngatikuyeuchidzei kuti kubatana pakati pevatengi kuchiri kuitika kuburikidza nepakati maseva uye, zvishoma, chokwadi chekutumira meseji pakati pevashandisi vaviri chinogona kuramba chichiratidzwa. Naizvozvo, hazvina musoro kushandisa email, masocial network uye chero mamwe masevhisi eruzhinji.
Saka ungaronga sei tsamba dzinosangana nezvose zvinodiwa zvekuchengetedza? Sechikamu chekuongorora kwedu, ticharasa nemaune nzira dzese dzisiri pamutemo kana dzinokakavadzana kuitira kuratidza kuti dambudziko rinogona kugadziriswa chete mukati mehurongwa hwemutemo. Iwe hauzodi chero spyware, hacker kana yakaoma-kuwana-software.
Anenge ese maturusi anosanganisirwa museti yezvishandiso zvakajairwa zvinouya nechero GNU/Linux system yekushandisa, uye kuvarambidza kunoreva kurambidza makomputa saizvozvo.
Webhu Yepasi Pose yakafanana newebhu hombe yemaseva, kazhinji inomhanyisa GNU/Linux sisitimu yekushandisa pavari uye mitemo yekufambisa mapaketi pakati pemaseva aya. Mazhinji emasevha aya haawanikwe kuti abatane zvakananga, zvisinei, kunze kwawo, kune mamirioni mamwe maseva ane kero dzinowanikwa dzinoshanda isu tese, achipfuura nepakati pehuwandu hwetraffic. Uye hapana achazombotsvaga tsamba yako pakati pemhirizhonga yese iyi, kunyanya kana isina kumira mushe neimwe nzira inopesana neyakajairwa kumashure.
Avo vanoda kuronga nzira yekutaurirana yakavanzika vanongotenga VPS (chaiyo muchina uri mugore) kubva kune mumwe wemazana evatambi varipo pamusika. Mutengo wenyaya, seusina kuoma kuona, madhora akati wandei pamwedzi. Ehe, izvi hazvigone kuitwa zvisingazivikanwe, uye chero zvakadaro, muchina uyu chaiwo unosungirirwa kune yako nzira yekubhadhara, uye nekudaro kune chako chitupa. Nekudaro, vazhinji vanotambira havana basa nezvaunomhanyisa pahardware yavo chero iwe usingapfuure miganho yavo yekutanga, senge huwandu hwetraffic inotumirwa kana kubatana kuchiteshi 23.
Kunyangwe mukana uyu uripo, hazvina zvazvinobatsira kuti ashandise madhora mashoma aakawana kubva kwauri kuti akutarisewo.
Uye kunyangwe kana achida kana kumanikidzwa kuita izvi, anofanirwa kutanga anzwisisa kuti ndeupi rudzi rwesoftware yauri kushandisa zvakananga uye, zvichibva paruzivo urwu, gadzira hurongwa hwekutevera. Izvi hazvizove zvakaoma kuita nemaoko, asi automating iyi maitiro ichava basa rakaoma zvakanyanya. Nechikonzero chimwe chete ichocho, kuchengetedza traffic yese inopfuura nepasevha yako hazvizove zvine pundutso kunze kwekunge iwe watanga wauya kutarisiro yeakakodzera zvimiro zvinoda kuita izvi.
Nhanho inotevera ndeyekugadzira nzira yakachengeteka uchishandisa imwe yenzira dzakawanda dziripo.
- Nzira iri nyore ndeyekugadzira yakachengeteka SSH yekubatanidza kune server. Vatengi vakati wandei vanobatana kuburikidza neOpenSSH uye vanotaurirana, semuenzaniso, vachishandisa madziro command. Cheap uye anofara.
- Kusimudza sevha yeVPN uye kubatanidza vatengi vakati wandei kuburikidza nepakati server. Neimwe nzira, tsvaga chero chirongwa chekutaura chenzvimbo network uye enda mberi.
- Nyore FreeBSD NetCat yakangoerekana yavaka-mukati mashandiro echinyakare asingazivikanwe chat. Inotsigira encryption uchishandisa zvitupa uye zvimwe zvakawanda.
Hapana chikonzero chekutaura kuti nenzira imwechete, kuwedzera kune mameseji akareruka, unogona kutamisa chero mafaera. Chero yeiyi nzira inogona kuitwa mu5-10 maminetsi uye haina kuoma nehunyanzvi. Iwo mameseji anozoita kunge akareruka encrypted traffic, inova ndiyo yakawanda traffic paInternet.
Iyi nzira inonzi steganography - kuvanza mameseji munzvimbo dzisina anombofunga kuzvitsvaga. Izvi pachazvo hazvivimbise kuchengetedzwa kwetsamba, asi zvinoderedza mukana wekuonekwa kwayo kusvika zero. Uye zvakare, kana sevha yako iri zvakare mune imwe nyika, maitiro ekutora data anogona kunge asingagoneke kune zvimwe zvikonzero. Uye kunyangwe kana mumwe munhu akawana mukana wazviri, saka tsamba yako kusvika panguva iyoyo kazhinji haizokanganisike, nekuti, kusiyana neruzhinji masevhisi, haina kuchengetwa munzvimbo chero kupi (izvi, zvechokwadi, zvinoenderana nesarudzo yawakasarudza nzira kutaurirana).
Nekudaro, vanogona kundipikisa kuti ndiri kutarisa munzvimbo isiriyo, masangano ezvehungwaru enyika akafunga zvese nezvese, uye ese encryption protocol ave nenguva aine maburi ekushandisa mukati. Chirevo chine musoro chose, tichipihwa nhoroondo yenyaya. Chii chekuita munyaya iyi?
Yese encryption masisitimu ayo ari pasi pemazuva ano cryptography ane imwe pfuma - cryptographic simba. Zvinofungidzirwa kuti chero cipher inogona kutsemuka - ingori nyaya yenguva uye zviwanikwa. Zvakanakisa, zvinodikanwa kuve nechokwadi kuti maitiro aya haangobatsiri kune anorwisa, zvisinei nekuti iyo data yakakosha sei. Kana kuti zvakatora nguva yakareba zvekuti panguva yekubira data haichazove yakakosha.
Mashoko aya haasi echokwadi zvachose. Ndizvo chaizvo kana tichitaura nezve anonyanya kuvharidzirwa maprotocol ari kushandiswa nhasi. Zvisinei, pakati pemarudzi akasiyana-siyana e-ciphers, pane imwe inopesana zvachose nekuputika uye panguva imwechete iri nyore kunzwisisa. Zvinotendwa kuti hazvibviri kubira kana mamiriro ese akazadzikiswa.
Pfungwa iri kuseri kweVernam Cipher iri nyore - kutevedzana kwemakiyi asina kujairika anogadzirwa pachine nguva iyo mameseji anozovharirwa. Uyezve, kiyi yega yega inoshandiswa kamwe chete encrypt uye decrypt meseji imwe. Muchiitiko chakareruka, tinogadzira tambo refu yemabhaiti asina kurongeka uye tinoshandura yega yega yemeseji kuburikidza neXOR mashandiro neinowirirana byte mukiyi uye toitumira zvakare pamusoro peiyo isina kunyorwa chiteshi. Zviri nyore kuona kuti cipher iri symmetric uye kiyi ye encryption uye decryption yakafanana.
Iyi nzira ine zvipingamupinyi uye haiwanzoshandiswa, asi iyo inobatsira inowanikwa ndeyokuti kana mapato maviri akabvumirana pane kiyi mberi uye iyo kiyi haina kukanganisa, iwe unogona kuva nechokwadi chokuti data haizoverengwi.
Chinoshanda sei? Kiyi inogadzirwa pachine nguva uye inoparidzirwa pakati pevatori vechikamu kuburikidza neimwe nzira. Inogona kutamiswa panguva yemusangano wega pandima isina kwayakarerekera, kana zvichibvira, kuitira kubvisa zvachose kuongororwa kunobvira, kana kungotumirwa netsamba ine USB flash drive. Tichiri kurarama munyika umo pasina tekinoroji kugona kuongorora ese midhiya inoyambuka miganhu, ese ma hard drive uye mafoni.
Mushure mekunge vese vatori vechikamu mutsamba vagamuchira kiyi, nguva yakareba ingapfuura isati yasvika chaiyo yekutaurirana musangano, izvo zvinoita kuti zvinyanye kuoma kupikisa iyi system.
Imwe byte mukiyi inoshandiswa kamwe chete kuvharidzira chimiro chimwe chete che meseji yakavanzika uye kuibvisa nevamwe vatori vechikamu. Makiyi akashandiswa anogona kuparadzwa otomatiki nevose vatori vechikamu mutsamba mushure mekuendesa data. Kana wachinjana makiyi akavanzika kamwe chete, unogona kutumira mameseji nevhoriyamu yakazara yakaenzana nehurefu hwavo. Chokwadi ichi chinowanzotaurwa sechisina kunaka cheiyi cipher; zvinonyanya kunakidza kana kiyi ine hurefu hushoma uye isingaenderane nehukuru hweshoko. Zvisinei, vanhu ava vanokanganwa nezvekufambira mberi, uye nepo ichi chaiva chinetso munguva yeHondo Yemashoko, harisi dambudziko rakadaro nhasi. Kana isu tichifungidzira kuti kugona kwevezvenhau vemazuva ano haaperi uye mune yakanyanya mwero kesi isu tiri kutaura nezve gigabytes, saka yakachengeteka nzira yekutaurirana inogona kushanda nekusingaperi.
Nhoroondo, iyo Vernam Cipher, kana imwe-nguva pad encryption, yaishandiswa zvakanyanya panguva yeCold War kuendesa zvakavanzika meseji. Kunyangwe paine zviitiko apo, nekuda kwekusava nehanya, mameseji akasiyana akavharidzirwa ane makiyi akafanana, ndiko kuti, maitiro ekunyorera akaputswa uye izvi zvakavatendera kuti vadzingwe.
Zvakaoma here kushandisa nzira iyi mukuita? Izvo zvidiki, uye otomatiki maitiro aya nerubatsiro rwemakomputa emazuva ano ari mukati mekugona kweanovice amateur.
Saka pamwe chinangwa chekuvharira ndechekukonzera kukanganisa kune chaiyo Telegraph mutumwa? Kana zvakadaro, pfuura zvakare. Mutengi weTeregiramu kunze kwebhokisi anotsigira maseva eproxy uye SOCKS5 protocol, iyo inopa mushandisi mukana wekushanda kuburikidza nemaseva ekunze asina kuvharirwa IP kero. Kutsvaga yeruzhinji SOCKS5 server yenguva pfupi haina kuoma, asi kumisikidza sevha yakadaro iwe paVPS yako kwakatonyanya nyore.
Kunyangwe pachichave nekurova kune iyo messenger ecosystem, sezvo kune vazhinji vashandisi izvi zvirambidzo zvicharamba zvichigadzira chipingamupinyi chisingakundike uye mukurumbira wayo pakati pehuwandu uchatambura.
Saka, ngatipfupikisai. Yese hype yakatenderedza Telegraph ndeye hype uye hapana chimwe. Kuivharira nekuda kwezvikonzero zvekuchengetedzwa kwevanhu hakuna hunyanzvi hwekunyora uye hakuna maturo. Chero zvimiro zvinonyanya kufarira tsamba dzakachengeteka zvinogona kuronga chiteshi chavo vachishandisa akati wandei nzira dzekuwedzera, uye, chii chinonyanya kufadza, izvi zvinoitwa zvakapusa, chero paine mukana wekuwana kune network.
Iyo ruzivo rwekuchengetedza kumberi nhasi haifukidze vatumwa, asi vakajairwa vashandisi vetiweki, kunyangwe vasingazvizive. Indaneti yemazuva ano ndeyechokwadi iyo inofanirwa kuverengerwa uye mune iyo mitemo iyo kusvika munguva pfupi yapfuura yairatidzika kunge isingazununguki inomira kushanda. Kuvharira Teregiramu mumwe muenzaniso wehondo dzemusika weruzivo. Kwete yekutanga uye zvirokwazvo kwete yekupedzisira.
Makumi mashoma mashoma apfuura, pamberi pekukura kukuru kweInternet, dambudziko guru rakatarisana nemhando dzose dzemaagent network kwaive kumisa nzira yakachengeteka yekutaurirana pakati pavo uye kuronga basa ravo nepakati. Kudzora kwakasimba pazviteshi zveredhiyo zvakazvimiririra panguva yeHondo Yenyika Yechipiri munyika dzese dziri kutora chikamu (kunyoresa kuchiri kudikanwa nhasi), nhepfenyuro dzakaverengeka dzeCold War (dzimwe dzichiri kushanda nhasi), mafirimu madiki ari pasi peshangu - zvese izvi. zvinongotarisa zvinosetsa padanho idzva rebudiriro yebudiriro. Zvakare inertia yekuziva, kumanikidza muchina wehurumende kuvhara zvakasimba chero chiitiko chisiri pasi pekutonga kwayo. Ichi ndicho chikonzero kuvhara kero dze IP hazvifaniri kuonekwa semhinduro inogamuchirwa, uye inongoratidza kushaya kukwanisa kwevanhu vanoita zvisarudzo zvakadaro.
Dambudziko guru renguva yedu harisi kuchengetwa kana kuongororwa kwedata retsamba nemunhu wechitatu (ichi ichokwadi chinangwa chatiri kurarama nhasi), asi chokwadi chekuti vanhu pachavo vakagadzirira kupa iyi data. Pese paunopinda paInternet kubva kubrowser yako yaunofarira, gumi nemaviri zvinyorwa zvinotarisa kwauri, zvichirekodha kuti wakadzvanya sei uye kupi uye peji ripi rawakaenda. Paunenge uchiisa imwe application ye smartphone, vanhu vazhinji vanoona hwindo rekukumbira rekupa ropafadzo kuchirongwa sechipingamupinyi chinogumbura vasati vatanga kuishandisa. Pasina kucherechedza chokwadi chekuti chirongwa chisingakuvadze chiri kupinda mubhuku rako rekero uye chinoda kuverenga mameseji ako ese. Chengetedzo uye kuvanzika zvinotengeswa nyore nyore kushandisa. Uye munhu pachake kazhinji anozvidira zvizere neruzivo rwake rwemunhu, uye nekudaro nerusununguko rwake, nokudaro achizadza dhatabhesi dzemasangano epasirese uye ehurumende neruzivo rwakakosha nezvehupenyu hwake. Uye ivo pasina mubvunzo vachashandisa ruzivo urwu kune zvinangwa zvavo. Uye zvakare, munhangemutange yepurofiti, vanozozvitengesa kune wese munhu, vachiregeredza chero tsika nehunhu.
Ndinovimba kuti ruzivo rwuri muchikamu chino ruchakubvumidza kuti utarise patsva dambudziko rekuchengetedza ruzivo uye, pamwe, shandura mamwe maitiro ako paunenge uchishanda online. Uye nyanzvi dzichanyemwerera zvakasimba uye dzichienda mberi.
Rugare kumba kwako.
