[HTML] Zamezení kopírování

[viki_]

Tak jsem si ze srandy behem 5 minut naklikal ten Applet a vysledek je zde - ten vestaveny prohlizec sice nezobrazuje asi vsechno html korektne, ale kdyz s tim bude clovek pocitat pri navrhu stranek, da se to prezit - jo a nechodi hypertextove odkazy - schvalne jsem je zakazal. Kopirovat samozrejme nic nejde - dalo by se s tim vyhrat mnohem vic.

Omezeni je v tom, ze nepodepsany Applet muze otvirat pouze stranky z vlastniho URL, tzn. ze nebudou chodit externi odkazy, coz je ovsem na ochranu vlastnich stranek dostacujici.

podle me jsou ty java aplety uplne na ***.

znam hodne lidi kteri je maji zakazany, nebo vypnuty. takze se samozrejme nic nezobrazi a pristupnost webu klesa a klesa.

Applety jsou fakt na hovno - pro lidi, co tomu nerozumi a nebo maji Applety spojene pouze s tim Microsoftim shitem s M$JVM 1 .

Applety jsou silny nastroj - podepsany applet muze delat totez co normalni program vcetne pristupu na disk, sifrovani a spoustu jinych veci.

Ano, je to na taketo veci uplne geni(t)alne - urcite si kvoli takejto <>ovine budem instalovat VM od Sunu - a urcite nie som sam...

Niet za co

Rainbow: JRE ma cca 13 MB. Je to hodne, je to malo ? Vzhledem k tomu kolik jinych sracek ma clovek na disku mi to zase az tolik nepripada.

naprtosty souhlas. u mne stejny screen a stejny vysledek.

i stejny nazor.

tak na takove stranky bych kliknul ja osobne jednou a pak uz neee. flash mam rad, kdyz je dobre udelanej akceptuju i to ze to je nekdy velke ale tohle je fuuuuj. i sem si to stahnul a nainstaloval, ten balast okolo coz uz jen to by me odradilo. bleh

A co je na tom tak fuj ? Mas tam jen okno podobne jako ve flashi - ja se s tim nebudu srat, abych tady ve svym volnym case nekomu vyrabel nejakou peknou grafickou upravu. Jde o princip - kazdy rval, ze kopirovani HTML zabranit z principu nelze - a ejhle zda se , ze to jde a navic toho jde dosahnou neprilis slozitou cestou. Kdyz ti vadi Java, klidne se to da zrealizovat napr. ActiveX komponentou, ktera do toho okna natahne streva z IE. Blby kecy umi mit kazdej, ale sorry, moc toho z tebe konstruktivniho zatim nevypadlo

Proc se dnes JVM musi do Win instalovat, na to se zeptej nejakyho dementa Billa Gatese

ActiveX Vies, ze ludia pouzivaju aj iny OS ako Windows a iny browser ako MSIE
Java -> vyskusaj si prehliadac Links...

[Glottis]

mno a ja ti rikam ze i z tohohle ten text jde jednoduse vytahat jde, sice ne prostym ulozenim a da to vic prace (i kdybych jak rikal nekdo to mel prepsat ruco ) ale jde to. btw nevypadlo a nevypadne. naprosto nenavidim takovehle weby. omylem tuknu pravim tlacitkem a hlaska ze neco nesmim.

Ach boze

[viki_]

Soudruzi a co rikate na tohle ? Je to trosku vylepseny napad s tim kodovanim stranky v javascriptu (to ze to nejde jsem se opravdu unahlil) Sice to zatim mrsi diakritiku, ale kdyby sis tim clovek trosku vic vyhral, urcite by to slo opravit. V tomto pripade lze samozrejme ze stranky normalne kopirovat - se zdrojovym HTML uz to ale nemusi byt tak trivialni, kdyz by se pouzilo krome B64 jeste nejake jednoduche sifrovani

Je to pouze cisty JavaScript, takze neni nutne nic instalovat.

jde to a ani to není moc náročný. stačí si stáhnout program, kterej umí zazipovat stránku interně. Tzn i když se vám stránka pak nahraje, rozzipuje a zobrazí tak se pořád jako zdroj zobrazuje ta zazipovaná verze, a to i když onu stránku uložíte.

příklad: moje stránky na http://www.memor.cz - schválně esi z toho framu s ovládacími tlačítky nalevo dostanete zdrojový kód ve srozumitelné podobě

no opera to nepřečte, internet explorer to přečte v pohodě, mozilla zřejmě jen s nastavenou západní codepage (Windows-1252 a možná i ISO-8895-1)

[viki_]

Ten kod framu vlevo ale neni rozhodne v zipu - je to jen obycejne kodovani js funkci escape() - cili skoro totez jako B64 - zdroj se ziska snadno pomoci unescape().

Aby se s tim clovek nemusel jebat ve velkem, muselo by se to hodit do nejakeho jednoducheho parseru, coz by nebyl vetsi problem.

V prvni casti je v escapovanem stringu deklarovana function hp_d01() s kterou se dela vetsina dalsich prasaren na strance a dal to pokracuje tim, ze se teto funkci predhazuji escapovane retezce. V druhe casti jsou dalsi JS funkce atd. atd.
Neni to nijak slozita ochrana - je jen jebacka rozebirat ty prihlouple scripty, ale problem to neni...

hp_ok=true;
function hp_d01(s){
if(!hp_ok)return;
var o="",ar=new Array(), os="",ic=0;
for&#40;i=0;i<s.length;i++&#41;&#123;
  c=s.charCodeAt&#40;i&#41;;
  if&#40;c<128&#41;c=c^2;
  os+=String.fromCharCode&#40;c&#41;;
  if&#40;os.length>80&#41;&#123;
    ar&#91;ic++&#93;=os;os=""
  &#125;
&#125;
o=ar.join&#40;""&#41;+os; 
return o;
&#125;

druha cast je tady:

<SCRIPT LANGUAGE="JavaScript"><!--
function hp_ne&#40;&#41;&#123;return true&#125;onerror=hp_ne;function hp_cm&#40;&#41;&#123;return false&#125;function hp_md&#40;e&#41;&#123;mac=navigator.userAgent.indexOf&#40;'Mac'&#41;!=-1;if &#40;document.all&#41;&#123;if&#40;event.button==2||&#40;mac&&&#40;event.ctrlKey||event.keyCode==91&#41;&#41;&#41;&#123;return false&#125;&#125;else&#123;if&#40;e.which==3||&#40;mac&&&#40;e.modifiers==2||e.ctrlKey&#41;&#41;&#41;&#123;return false&#125;&#125;&#125;if&#40;navigator.appName.indexOf&#40;'Internet Explorer'&#41;==-1||&#40;navigator.userAgent.indexOf&#40;'MSIE'&#41;!=-1&&document.all.length!=0&#41;&#41;&#123;if&#40;document.all&#41;&#123;mac=navigator.userAgent.indexOf&#40;'Mac'&#41;!=-1;version=parseFloat&#40;'0'+navigator.userAgent.substr&#40;navigator.userAgent.indexOf&#40;'MSIE'&#41;+5&#41;,10&#41;;if&#40;!mac&&version>4&#41;&#123;document.oncontextmenu=hp_cm&#125;else&#123;document.onmousedown=hp_md;document.onkeydown=hp_md&#125;&#125;else if&#40;document.layers&#41;&#123;window.captureEvents&#40;Event.MOUSEDOWN|Event.modifiers|Event.KEYDOWN&#41;;window.onmousedown=hp_md;window.onkeydown=hp_md&#125;else if&#40;document.getElementById&&!document.all&#41;&#123;document.oncontextmenu=hp_cm&#125;&#125;//--></SCRIPT>

atd. az do zblbnuti

A ze 4. casti ?

2viki_: Je vidět, kdo tady rozumí tématu

[Rainbow]

No vsak - kto chce (a vie ), ten kod odtial uz nejako dostane. Takze je to dobre na odradenie "obycajnych" userov a rovnako aj na odradenie pouzivatelov Opery

[viki_]

šaman: Tak to asi trosku prehanis , ja myslim, ze na to musi prijit kazdy, kdo umi zaklady javascriptu.

Pokud chce nekdo udelat takovou stranku, ktere nebude nikdo rozumet, tak staci, kdyz si doc z wordu necha ulozit jako HTML

Tomu akoze-HTML casto nerozumeju ani browsery, dokonca aj MSIE s tym ma niekedy problemy

[šaman]

2Rainbow: a o to přece jde, ne? Zabránit lamám ukrást ti tvůj vytvor. A non-lamy si to klidně napíšou sami.

2viki_ : Nebuď skromný, argumenty jsi umlátil oponenty , kteří ten dlooouhý příspěvek ještě teď čtou

[acheron]

no to sem z toho blázen

musím zkusit něco jiného
