    Dotaz: Zašifrování HTML stránky, aby nebyl vidět zdroják

    5.1.2021 18:55 Prďoch
    Zašifrování HTML stránky, aby nebyl vidět zdroják
    Přečteno: 8468×
    Dobrý den,

    pomocí javascriptu jsem sice zakázal funkce pro kopírování a použití F-12, nicméně bych potřeboval nasměrovat jak celý HTML kód skrýt třeba pomocí base64 nebo AES 256, většina online encryptorů generuje zároveň do zacryptovaného HTML také trojany atp.

    Má někdo s tímto zkušenost? Děkuji moc, přeji poklidný Nový Rok 21'

    Blbost nejde to.

    Aby prohlížeč něco zobrazil potřebuje dodat data, samozřejmě je můžeš generovat jak chceš, ale prohlížeči je nějak pošleš a to lze zobrazit.

    Samozřejmě lze získání zdrojového kodu stížit, ale vždy to co server pošle lze zachytit.

    tak jak je možné že jsem kdysi viděl stránku co neměla vidět žádný zdroják po zadání ctru -u, nebo v webkonzole nebylo nic, jen čistá bílá stránka a přece měl web obsah, obrázky..

    Existují metody jak upravit HTML do base64 atd, nemohu se s tím smířit, že to nejde. Kdysi jsem nato narazil u nějakého Inda co se tím chlubil na FB.Kdybych to neviděl tak o tom nepíši :-/

    scrollbar... scrollbar tam nebyl? Ze by to bylo proste jen "za rohem" posunute taby/mezerami? :-)

    Jinak ctrl-u v prohlizeci zobrazi zdrojak - neprovadi se to, takze ten je zobrazovan naopak celkem citelne a stranka by nemela ovlivnit, jak to bude barevne... :-)

    Co mi bude branit misto otevreni ve firefoxu to proste stahnout wgetem? Ten to opravdu neprovede a poslusne vse ulozi. Cim si to pak prohlidnu je moje vec. A prohlidnu.

    Takze bych se opravdu zamyslel, jestli zrovna toto "musi" zustat utajene. :-/ >kus se zamyslet, co tam bude tak tajneho, ze se to "nesmi" zobrazit. Jestli by spis nemel byt omezen pristup na celou stranku jen lidem, kteri tam maji co delat.

    Na wget to za jistých okolností nefunguje.

    Nastavte nějaký server tak, aby stránka byla běžnému GUI prohlížeči doručena (na úrovni HTTP) a já, stejně jako mnozí další na tomto webu, Vám mohu s jistotou ukázat způsob, kterým ji získám wgetem nebo curlem. Toto řešení je poněkud absurdní – doporučuji přečíst RFC 7230 a související.

    Ctrl+U myslím zobrazuje originální zdroják, ne generovaný zdroják, takže je možné, že tam bude jenom krátký javascriptový loader a zbytek stránky se vygeneruje jím. Ale aby tam „nic nebylo“ to je buď nesmysl, nebo bug v prohlížeči. Nejlepší na tyhle věci je odposlechnout si to nějakým Burp proxy. Téměř určitě ses prostě špatně díval.

    Developer console se dá nějak detekovat a ta detekce se dá zase obejít.
    Existují metody jak upravit HTML do base64 atd
    To samozřejmě jde. Ale co mi brání si do base64 dekódovat, nebo si přečíst to vygenerované HTML? Každopádně se kód dá tak zprasit, že ho nikdo číst nebude.

    To bylo proto, ze CTRL+U ve Firefoxu ukaze zdrojak tak, jak jej dostal od serveru. Pokud je ten web generovany Javascriptem na klientu, bude takovy kod vypadat dost stroze a obsahovat jen odkaz na ten skript, ktery tu stranku vykresli. Resi se to tak, ze zmacknes CTRL+SHIFT+C a podivas se na vygenerovane HTML a pripadne HTTP requesty.

    Ind, ktery ti neco podobneho tvrdil se z tebe pravdepodobne jen snazil vymamit prachy za ten jeho "neprustrelny" sifrovator.

    Co to ma vlastne robit ? (obrazok v prilohe :D ) ...


    ... este z 90tych rokov, ked sa web stranky bezne pisali v notepad-e, si pamatam tento "prazdny zdrojak". Strasne vela novych riadkov, strasne vela medzier a zhutneny kod (odstranene veci, co niesu potrebne na zobrazenie html). Na takej stranke ked si dal niekto zobrazit zdrojovy kod, tak sa zobrazilo prazdne okno. Pozornejsi si vsimli sktrolovatko a "hladali html". Sikovnejsi dali ctrl+f bud nejaku cast html (napr html, head, body, etc.), alebo text, co je na obrazovke ... osobne si myslim, ze ten "prazdny" zdrojak bude presne toto iste. So zbytkom suhlasim. Moze to byt akokolvek obfuskovane, kedze browser potrebuje ciste html na vykreslenie stranky, tak v browseri bude vysledne html a bude s dat precitat. Na tej HTML Guard stranke som stravil mozno o 2 sekundy dlhsie, nez som nasiel potrebne zobrazenie v menu, namiesto klasickeho mys + "inspect element".

    Už vám to tady napsalo několik lidí, jak to bylo – že tam nebyl prázdný zdroják, ale jenom byl pomocí mezer nebo prázdných řádků odsunutý mimo vaše zorné pole. A možná byl zdroják co nejmenší a jen načítal nějaký skript, který zařídil samotné zobrazení stránky. Jestli jste ten zdroják studoval stejně pozorně, jako zdejší diskusi, není divu, že jste to přehlédl.

    Jistě. A když někdo bude tvrdit, že měl v ruce obyčejný žulový kámen, který najednou začal padat nahoru, také po něm budeme chtít ten kámen jako důkaz. Sice existují názory, že to není možné, protože gravitačně se objekty vždy přitahují – ale ten kámen by ty názory mohl vyvrátit nebo nevyvrátit.

    Pořád někdo vymýšlí nějaké kompresní algoritmy, přitom je to tak jednoduché – vytvoříte stránku, schováte zdrojový kód, aby měla stránka 0 bajtů, a máte zkomprimováno na maximum.

    Konstruktivnosti debaty nejvíc prospěje, když se v ní nebudou vyskytovat bláboly jako že z 0 bajtů dokáže prohlížeč vyčarovat celou webovou stránku, kterou zobrazí.

Pokud to je schopen precist prohlizec, je schopen to odchytnout a reprodukovat i clovek. Muze se mluvit o nejake obfuskaci, o schovani kodu v konzoly prohlizece za rohem, ale magie typu server posle neco zasifrovaneho sifrou kterou nikdo nezna a browser to zobrazi ale clovek ne, nebo dokonce server posle prazdno ale prohlizec to zobrazi, ta tady nefunguje.

    Právě proto, že je to tak elementární, jsem to přirovnal ke gravitaci. Ani není potřeba vědět nijak podrobně, jak prohlížeč funguje. Stačí vědět akorát to, že jediné, co prohlížeč umí, je zobrazit HTML dokument, jeho vzhled načíst z CSS, v dokumentu zobrazit nějaká multimédia a umí s tím manipulovat pomocí JavaScriptu. Přesto se tu sáhodlouze debatuje, jestli se nemůže stát zázrak a prohlížeč nemůže zobrazit požadovanou stránku i jen tak, bez předpisu pro její zobrazení. A dokládá se to zcela vážně míněným argumentem „já jsem to někde viděl“. Ta neochota se nad situací zamyslet a místo toho náhodně hledat zázrak je až děsivá.

    Přidám se k těm "někde jsem to viděl", nepamatuju si pochopitelně skoro nic. Autor použil nějakou obskurní funkci konkrétního prohlížeče, pomocí které dokázal zdroják protlačit postranním kanálem, který se při view-source nezobrazil. Prohlížeč ten zdroják měl, ve vývojářských nástrojích se dal zobrazit. V praxi to bylo nepoužitelné, se šifrováním to nemělo nic společného.

    Tohle nepoužívá žádnou obskurní funkci webového prohlížeče, ale standardní API. Když si to uložíte do souboru a zobrazíte v prohlížeči, bude to dělat přesně to, co popisujete. Akorát níže uvedený kód na první pohled uvidíte, když si zobrazíte zdrojový kód stránky.
    <script>fetch("/test.html").then(resp => resp.text()).then(text => document.write(text));</script>
    
    Nebo ten skript nemusíte inlinovat. Použijete externí skript, a nějak hezky ho pojmenujete, třeba mezerou nulové šířky. Takže pak celý HTML soubor bude obsahovat jenom tohle:
    <script src="​" />
    
    Spousta lidí se pak bude dušovat, že zdrojový kód stránky byl úplně prázdný…

    Ohledně toho schování zdrojáku – moderní prohlížeče to asi mají všechny ošetřené, ale teoreticky je tu ještě možnost imitovat GUI prvky prohlížeče. Uživatel klikne pravým tlačítkem myši, zobrazí se něco, o čem se domnívá, že je to nativní kontextové menu, ale je to podvržené tou webovou stránkou, a po kliknutí na tlačítko, které vypadá, že zobrazuje zdroják, se otevře prázdné nové okno.

    V prohlížečích před pár lety podobné chyby byly (to je právě ta velká výhoda toho, když se zahodí desítky let vývoje stávajících operačních systémů a jejich roli začnou přebírat prohlížeče dokumentů), ale jsou to prostě chyby. Nikdy to nebude fungovat dlouhodobě a vždycky to půjde obejít wgetem se správně nastaveným User-Agentem.

    Je zbytečné na tom trávit čas a pokud to chce zákazník, jak někdo píše výše, je potřeba mu vysvětlit, že je to nesmysl. Nemá to absolutně žádný význam. Řešit nějaké blokování User-Agenta na serveru, jak naznačuje tazatel výše, je akorát způsob, jak omylem vytrestat legitimní uživatele s méně rozšířenými prohlížeči a boty (např. crawlery vyhledávačů). Přesto je stále otázkou jediného příkazu to obejít pro lidi, kterým by ten zdroják reálně k něčemu byl.

    Skrývání nebo šifrování zdrojáku je nesmysl. Jediné, co může mít nějaký význam, je obfuskace, ale i tam se díky vzniku developerské konzole, headless prohlížečů a pokrokům na poli AI prostor pro smysluplné využití neustále tenčí.

    Proč by to skrývání zdrojáku vůbec někdo řešil? Napadají mě jen samé fishy věci typu těžba bitcoinů bez vědomí uživatele.

    Tak jsem našel takovou stránku, hele.
    < Jenda`> Webová stránka dne: http://samy.pl/
    < Jenda`>  - zdroják si to přepisuje a protože browsery už neumí udělat "view page source" (ale jenom "generated source"), tak ho nemáte jak získat
    < Jenda`>  - detekce otevřené developer console
    < Jenda`>  - přes ZAP Proxy to nefunguje
    < Jenda`>  - BurpSuite to zacyklí v nekonečné smyčce a zatuhne

    • Detekce wgetu (i když si nastavíte user agent ze skutečného browser)
    • Kupodivu wget přes Burp to nedetekuje. Takže je to nějaká magie na nižší úrovni (TLS handshake?)

    FYI:
    • Detekce wgetu a asi ZAPu je založená na Accept hlavičce. Tohle funguje:
      wget --header="Accept-Encoding: gzip, deflate" --no-check-certificate --user-agent="Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0" https://samy.pl/ -O - | gzip -d
      
      wget --header="Accept-Encoding: gzip, deflate" --header="Cookie: __utms=1" --header="Referer: https://samy.pl/" --user-agent="Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0" https://samy.pl/load.js -O - | gzip -d
    • Ten Burp se předpokládám zasekne kvůli tomu množství whitespaců v tom dokumentu.
    • Co se týče divočin v samotném browseru, s tím neporadím, protože modernímu web developmentu nerozumím.

    <p>There is a <code>console</code> "clearing" API that is mentioned in <a href="https://stackoverflow.com/a/31261830/7024476">this answer</a>.</p>
    
    <p>Here's what I think is happening:</p>
    
    <p>First, I think Google Chrome DevTools emits an event when it is open/launched.
    The page author listens for this 'launch' event with the following handler logic:</p>
    
    <ol>
    <li>Run a <code>chrome.devtools.inspectedWindow.eval</code> <a href="https://developer.chrome.com/extensions/devtools_inspectedWindow" rel="nofollow noreferrer">DevTools inspection API</a> </li>
    <li>Set <code>document.body.innerHTML</code> to the winky-face div</li>
    <li>Also, a <a href="https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/setInterval" rel="nofollow noreferrer"><code>setInterval</code></a> that executes a <code>console.clear()</code> before the <code>console.log()</code> of "no source for you".</li>
    </ol>
    
    <p>I also inspected the EventListeners tab of Chrome DevTools while reading the "no source for you"-page.</p>
    
    <p>Unfortunately, the two event listeners you can view don't seem to do <em>anything useful</em>: </p>
    
    <ul>
    <li>one returns <code>false</code></li>
    <li>the other wires together forms and their associated submit actions.</li>
    </ul>
    
    <p>Hope this helped</p>

    <p>hahaha, this is a good one, you should not expect less from samy!</p>
    
    <p>Now I see why people think it is the wrong answer (the source get replaced if you do otherwise) </p>
    
    <p>1.Navigate to site with inspector open there you end up with "No source for you! You found easter egg #7."</p>
    
    <p>2.and then check the source to find Easter egg #2:</p>
    
    <pre><code>view-source:https://samy.pl
    </code></pre>
    
    <p>you will see:</p>
    
    <pre><code>/*
    No source for you! Easter egg #2
    *// AFTER SOME LONG WHITE SPACES HERE  /.source.replace(/.{7}/g,function(w){document.write(String.fromCharCode(parseInt(w.replace(/ /g,'0').replace(/   /g,'1'),2)))});
    </code></pre>
    
    <p>This is the way he loads the site(by injecting js), by replacing two type of white spaces for 1 and 0 and parsing that to char code by some regex and then that to string of course :D</p>
    
    <p><a href="https://de.wikipedia.org/wiki/Whitespace_(Programmiersprache)" rel="nofollow noreferrer">https://de.wikipedia.org/wiki/Whitespace_(Programmiersprache)</a></p>
    
    <p>If you paste that part to a js console, you will get the tags that loads the page.</p>
    
    <p><a href="https://i.stack.imgur.com/aQ6wj.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/aQ6wj.png" alt="enter image description here"></a></p>
    
    <p>ps. to see the rendered source, just load the page normaly and hit F12 after disabling javascript.</p>
    
    <p>Have fun!</p>

    V krajním případě můžeš celou tu stránku (text, obrázky, …) renderovat na serveru do bitmapy a tu posílat do prohlížeče, kde se JavaScriptem vykreslí. Kliknutí myší (např. na odkaz) nebo stisky kláves (např. při vyplňování formuláře) budeš zase tím JavaScriptem posílat zpět na server a tam interpretovat (dle pozice v bitmapě, kde událost nastala). Takže to bude takové webové VNC.

    Akorát i v tomhle případě si uživatel může udělat snímek obrazovky, tím si uložit obrázky (případně i nahrát video), a následně nad tím může pustit OCR a dostat z toho i původní text.

    Pokud ten obsah není dostatečně hodnotný, tak pouze plýtváš svým časem. A pokud hodnotný je, tak věř, že někdo ten postup popsaný v předchozím odstavci automatizuje a udělá dostatečně snadným pro všechny uživatele.

    Omlouvám se za mirný off topic, ale to mi trochu pripomělo projekt browsh ( browsh ). Ten renderuje stránku do bitmapy a následně ji převede na ASCII art, nebo tak něco a funguje tam i JavaScript;) Akorát ne všechny terminály si s tím správně poradí.

    Pěkné. Myslím, že už jsem to někde zahlídl, ale zapomněl jsem, jak se to jmenuje. Takže díky za odkaz.

    Podařilo se mi to na mém počítači. Server apache2 , Linux mint . Funguje to jen pro Firefox. V PHP mám if (něco) {generuj stránku1} else {generuj stranku2} . Pokud něco=pravda, vygeneruje stránku1 , ale CTRL U ukáže zdroják ze stránky2. Pokud v bloku else není nic , zobrazí prázdnou stránku. To samé při hostování na VPS funguje správně, takže to nemohu ukázat. Asi to bude kombinace několika chyb. Nejsem expert, zkoumat se mi to nechce. Ale možná to někoho nakopne správným směrem.

    Ten zdroják do prohlížeče prostě dorazí, jinak by prohlížeč neměl co zobrazovat. Je možné zdroják upravit tak, aby v GUI prohlížeče byl zobrazený tak, že ho méně zkušený uživatel přehlédne. Je možné teoreticky zneužít nějakou chybu GUI prohlížeče tak, aby nešel vůbec zobrazit (pokud např. prohlížeč bude umět zobrazit jen omezený počet řádků nebo sloupců). Je možné využít toho, jak se prohlížeč chová při zobrazení zdrojáku (některé prohlížeče myslím zdroj stáhnou znova) a poslat mu jiný zdroják. Pořád ale platí, že to stažení do prohlížeče, které něco zobrazí, posílá zdrojový kód té stránky. Takže stačí otevřít si vývojářské nástroje, odpověď zachytit a uložit do souboru na disk, a pak už si ten zdroják můžete prohlížet libovolným programem, který se nenechá zmást spoustou mezer nebo prázdných řádků.

    Všechny ty komentáře, jak někdo někde namouduši viděl stránku, která neměla žádný zdroják, znamenají akorát jedinou věc – dotyčný neovládá prohlížeč tak dobře, aby dokázal zdroják stránky získat. Je to takhle strašně jednoduché.

    Napadá mě obsah vložený přes CSS a blok s CSS importem následně přepsaný na nic.

    Jinak za ta léta, nabraly prohlížeče takového balastu, že bych se nedivil, že se tam nějaká skulina najde.

    Už jsme viděli lecos. Namátkou: VRML, WAP, Java Applety, Active-X, Flash, Silverlight obrázky převedené na base64 a embedované dovnitř HTML, ... O světě JS, WebAssembly a Nodeismů ani nemluvě.

    Pro pobavení (v praxi nejspíš nepoužitelné): Další taková. Takhle to funguje - je to napsané v CSS (pomocí různých :before, :after a inlinovaného SVG) a CSS se, zdá se, dá vložit pomocí HTTP hlavičky Link.

    Existuje několik způsobů, jak zašifrovat HTML kód, aby nebyl viditelný zdrojový kód ve webovém prohlížeči:

    Použití JavaScriptu k šifrování kódu a dešifrování při načítání stránky.

    Použití PHP nebo jiného serverového jazyka k šifrování kódu a dešifrování při načítání stránky.

    Použití nástrojů pro kompilaci HTML kódu, jako je HTML Protector nebo Armadillo HTML Protector.

    Je důležité si uvědomit, že žádná z těchto metod není stoprocentně účinná a zdrojový kód může být stále zobrazen pomocí nástrojů pro ladění prohlížeče nebo pomocí speciálních nástrojů pro dekompilaci kódu.

    Záleží co by tam mělo být za obsah/služby a jak moc by to mělo být "šifrované/nepřístupné". Čeho by se tím skrytím mělo docílit?

    Těch způsobů by se dalo použít víc. Namátkou
    • Generovat stránku jinde a pak posílat jen její screenshot, případně doplněný o HTML map s definovanými aktivními oblastmi.
    • Využít některou ze služeb anonymizátoru, a na serveru si hlídat, že tam může přistoupit jen klient s IP toho anonymizátoru.
    • Použití WebAssembly a šifrovat tam.
    • Použít např. interpret Pythonu v JavaScriptu https://brython.info/ a šifrovat kód ve vnořeném scriptu.
    • Posílat Ajaxem jen kousky stránky a postupně je zase mazat.
    • Generátorem obalit funkční kód stovkami divů, komentářů, prázdných HTML neblokových prvků, ...
    • Poslat jen textový obsah.
    • Poslat zvukovou nahrávku jak si tu stránku má uživatel představit...

    Pocit. Začne jednou větou uvedením do problému, pak vyjmenuje několik možností, z nichž některé jsou mimo (PHP), a zakončí to upozorněním že to nemusí být dobré.

    Když se na to dívám zpětně, tak tam jisté charakteristiky, které by nasvědčovali ChatGPT vidím. Toť otázka co z toho ale vyvozovat. Méně reagovat na příspěvky, které se tváří užitečně, ale zase tak moc nejsou?

    No a jak je to skutečně, to by nám mohl povědět Petr.
