Comment comprendre ce code [ function(p,a,c,k,e,d){} ] [Résolu]

[pierrot10]

Bonjour à tous,

Je suis face un problème chinois,
Je dois comprendre un code et avant tou j'aimerais savoir comment le rendre lisible. Il doit etre compacté et y aurait il le moyen de le rendre "décompacter"?

Aussi, pourriez-vous me mettre sur la piste? Que fait-il en gros?

Code :

eval(function(p,a,c,k,e,d){e=function(c){return(c<a?'':e(parseInt(c/a)))+((c=c%a)>35?String.fromCharCode(c+29):c.toString(36))};if(!''.replace(/^/,String)){while(c--){d[e(c)]=k[c]||e(c)}k=[function(e){return d[e]}];e=function(){return'\\w+'};c=1};while(c--){if(k[c]){p=p.replace(new RegExp('\\b'+e(c)+'\\b','g'),k[c])}}return p}('h(!j.21==1){7 $3=$}7 i={1c:0,11:"",6:{w:[],v:[],t:{H:0,G:0},x:[],C:[],U:j.U,1s:j.1r,13:j.13},1l:8(b){7 a=2o 2h();a.2m(a.2g()+27*24*1);1q.2c="22="+1X(b)+"; 26=/;2n="+a.2f()},1P:8(a,b){1Q(a){l"v":5.6.v.Y(b);r;l"w":5.6.w.Y(b);r;l"x":5.6.x.Y(b);r;l"C":5.6.C.Y(b);r;l"z":5.6.t.H=b;r;l"D":5.6.t.G=b;r}},2e:8(){h(1m(5.10!="1f")){5.10.2b("14").k("y","y");5.10.2a(8(){$3("q#X"+$3(5).B().B().k("K").S("V","")).W("E")});$3(".9 #1e").1G()}},1M:8(b,c){1Q(b){l"v":7 a=5.6.v.Q(c);h(a!=-1){5.6.v.R(a,1)}r;l"w":7 a=5.6.w.Q(c);h(a!=-1){5.6.w.R(a,1)}r;l"x":7 a=5.6.x.Q(c);h(a!=-1){5.6.x.R(a,1)}r;l"C":7 a=5.6.C.Q(c);h(a!=-1){5.6.C.R(a,1)}r;l"z":5.6.t.H=0;r;l"D":5.6.t.G=0;r}},29:8(){5.6={w:[],v:[],t:{H:0,G:0},x:[],C:[],U:j.U,1s:j.1r,13:j.13};$3(".9 :1b").k("y","");17(j.1i,j.1k);$3(".9 .1I").15("E");5.A()},1h:8(b){7 b=b||"2l";7 a=b.2k("2i");5.J=a[0];5.19=a[1];5.A()},2j:8(a){5.18=a||0;5.A()},1U:8(a){5.O=a;5.A(1g)},1B:8(){7 d=5.J?"&1R="+5.J:"";7 b=5.19?"&1W="+5.19:"";7 a=5.18?"&n="+5.18:"";7 c=5.O?"&p="+5.O:"";1O 1z+"/1y/1x/1V.23?"+d+b+a+c},A:8(c){5.O=c?5.O:1;7 b=5.1c?"20#1S":"u#1w";7 d=$3(b).1Z();7 a=$3(b).1Y();7 f=$3(b).1T()/2-25;7 e=$3(b).2d()/2-25;$3(b).1p("Z","2X");h($3(b+" #1d").I==0){$3(b).2W(\'<u K="1d" 1F="Z:1t;1u:0;1D:0;2U:.4;2O:\'+d+"12;1A:"+a+\'12;2R-2P:#2Q"></u><u 1F="Z:1t;1u:\'+e+"12;1D:"+f+\'12"><2L 1A="2M" 2S="\'+1z+\'/1y/1x/1d.2T"/></u>\')}h(5.11){5.11.2V()}5.11=$3.2N(5.1B(),{6:2J.2p(5.6)},8(g){$3("u#1w").2w(g);$3(b).1p("Z","")});5.1c=1}};$3(1q).2K(8(){h($3(".9 :y").I>0){i.10=$3(".9 :y");$3(".9 :1b").k("y","");$3(".9 #1e").2x()}$3(".9 :1b").T("14",8(){7 a=["v","C","w","x"];2v(7 b=0;b<a.I;b++){h($3(5).2u("2q"+a[b])){h($3(5).k("y")){i.1P(a[b],$3(5).m());$3("q#X"+$3(5).B().B().k("K").S("V","")).W("E")}F{i.1M(a[b],$3(5).m());h(i.6[a[b]].I==0||$3(5).B().B().2r(":y").I==0){$3("q#X"+$3(5).B().B().k("K").S("V","")).15("E")}}}}$3(".9 #1e").1G();i.A()});$3(".9 .1I").T("14",8(){7 b=$3(5).k("K").S("X","");7 a=$3(".9 #V"+b);a.1J(":1N")?$3(".9 q#1v"+b).k("L","1o"):$3(".9 q#1v"+b).k("L","2s");a.1L()});$3(".9 o#z, .9 o#D").T("2t",8(){17($3("o#z").m(),$3("o#D").m());1H(8(){h(1m(i.J)=="1f"){i.1h("1C")}F{i.A()}},2z)});h(j.2A){$3("u#2G 1E, u#2H 1E").T("14",8(){h($3("q#1n").k("L")=="1K"){$3("q#1n").k("L","1o")}F{$3("q#1n").k("L","1K")}$3("u.9").1L(2I,8(){h($(5).1J(":1N")){i.1l(0)}F{i.1l(1)}})})}$3("#s-P").s({2F:1g,P:1g,1a:j.1i,1j:j.1k,2E:1,2B:8(){h($3(".9 o#z").m()==$3(5).s("M","1a")&&$3(".9 o#D").m()==$3(5).s("M","1j")){$3(".9 q#16").15("E")}F{$3(".9 q#16").W("E")}h(1m(i.J)=="1f"){i.1h("1C")}F{i.A()}},2C:8(a,b){i.6.t.H=b.N[0];i.6.t.G=b.N[1];$3("o#z").m(b.N[0]);$3("o#D").m(b.N[1])}});17(j.1i,j.1k)});8 17(a,b){$3("#s-P").s("M","N",[a,b]).s("2D");$3("o#z").m(a);$3("o#D").m(b);i.6.t.H=a;i.6.t.G=b;h($3(".9 o#z").m()==$3("#s-P").s("M","1a")&&$3(".9 o#D").m()==$3("#s-P").s("M","1j")){$3(".9 q#16").15("E")}F{$3(".9 q#16").W("E")}}7 1H=(8(){7 a=0;1O 8(c,b){2y(a);a=28(c,b)}})();',62,184,'|||jq||this|data|var|function|LFoptions||||||||if|LFManager|LFsettings|attr|case|val||input||span|break|slider|price|div|attributes|features|tags|checked|price_low|sendRequest|parent|manufacturers|price_high|active|else|high|low|length|orderBy|id|class|option|values|page|range|indexOf|splice|replace|bind|convert|LFslide_|addClass|LFheader_|push|position|lastOptions|request|px|language|click|removeClass|LFheader_price|changeSliderValues|pageSize|orderWay|min|checkbox|sent|loadingMask|LFrestoreLast|undefined|true|sort|pricelow|max|pricehigh|saveState|typeof|StatFilter|expanded|css|document|category|idcategory|absolute|top|Stat|center_column|livefilter|modules|baseDir|height|getURI|price_asc|left|h4|style|fadeOut|delay|LFaccordeon|is|minimizedup|slideToggle|remove|hidden|return|add|switch|orderby|product_list|outerWidth|setPage|filter|orderway|escape|innerHeight|innerWidth|ul|compatibility|LFManagerState|php|||path|3600000|setTimeout|clear|each|trigger|cookie|outerHeight|restoreLast|toGMTString|getTime|Date|_|setPageSize|split|position_asc|setTime|expires|new|stringify|LF|find|minimized|keyup|hasClass|for|html|fadeIn|clearTimeout|1000|collapse|stop|slide|enable|step|animate|LFStyleFixed|LFStyleColumn|500|JSON|ready|img|50px|post|width|color|fff|background|src|gif|opacity|abort|append|relative'.split('|'),0,{}))

fais une recherche sur google avec "javascript unpacker"

Mais pour commencer tu as ceci :

Code :

eval ( function(p,a,c,k,e,d){e=function(c){return( ...

eval attend une chaine string
c'est donc que la closure function(p,a,c,k,e,d) va retourner une chaine
pour la visualiser, il suffit de supprimer l'eval et d'envoyer ce que la fonction retourne dans un textarea par exemple:

Après le code ayant été packed ... bonne chance pour t'y retrouver dans les variables !

En fait les variables(noms de fonctions) ont bien gardé des noms lisibles car la plupart des packer (configurés par défaut) ne diminuent les noms de variables que s'ils ont une portée locale (si l'on pacte un code complet, il est donc intéressant de l'englober d'une fonction de closure pour que le compresseur sache que la portée de toutes les variables est locale) ce qui n'a apparemment pas été le cas ici.

EDIT: Enfin, sauf les 2-3 variables locales à chaque fonction (a,b,c) mais comme celles-ci sont bien codées et assez courtes avec peu de variables. Ca reste lisible même avec des noms d'une seule lettre.


Illustration de la closure dont je parle avec le même outil(ou l'un de ses clones) utilisé que pour le code proposé par l'auteur du sujet :

http://javascriptcompressor.com/

si l'on compresse (avec l'option "Shrink variables") ceci :

Code :

var aaaaaaaaaaaaaaaaaaaaaaaa = function(gggggggggggggg){};

nous obtenons ceci :

Code :

var aaaaaaaaaaaaaaaaaaaaaaaa=function(a){};

alors si on rajoute du code (une closure) le résultat de la compression sera plus court (36 au lieu de 43 caractère dans cet exemple) :

Code :

(function(){var aaaaaaaaaaaaaaaaaaaaaaaa = function(gggggggggggggg){};})();

la compression donne ceci :

Code :

(function(){var b=function(a){}})();

Ok, super!
je vous remercie pour vos éclaircissements. Je vais regardé ceci, ce soir, chez moi.

Toute bonne soirée à vous
