[Javascript] sorgente "criptato" ???

[rayman2]

Ciao a tutti, volevo porvi questo dubbio: ho trovato uno script che è fatto in questo modo illeggibile.

eval(unescape('f%75%6ec%74%69%6f%6e%20%78%78%28%6e%29%20%7B%7a%20%3D%20%75%6ee%73ca%70e%28%6e%29%3B%76a%72%20%79%20%3D%20%27%27%3Bf%6f%72%20%28%69%3D0%3B%69%3C%7a%2e%6ce%6e%67%74%68%3B%69%2b%2b%29%20%7B%79%20%2b%3D%20%53%74%72%69%6e%67%2ef%72%6f%6dC%68a%72C%6fde%28%7a%2ec%68a%72C%6fdeA%74%28%69%29%2d1%29%3B%7Dd%6fc%75%6de%6e%74%2e%77%72%69%74e%28%75%6ee%73ca%70e%28%79%29%29%3B%7D'));xx('%3Dtdsjqu%21uzqf%3E%23ufyu0kbwbtdsjqu%23%3F%0Bepdvnfou/xsjuf%2639%2638%264Dq%2631bmjho%264E%2633dfoufs%2633%264F%264Dgpou%2631dpmps%264E%2633%2638%2Cdpmpvs%2C%2638%2633%2631tj%7Bf%264E%2633%2C2%2633%264F%2638%2Cuyu%266C1%266E%2C%2638%264D0gpou%264F%264D0q%264F%2638%263%3A%264Cjoefy%2631%264E%26311%264Cwbs%2631cfhjo%264Cwbs%2631foe%264Cwbs%2631wbmtus%264Cwbmtus%2631%264E%2631%2633%2633%2631%2C%2631qbsfou/bmm%60psefs%60upubmt%2639%263%3A%264Cwbs%2631efdqpjou%2631%264E%2631wbmtus/joefyPg%2639%2633/%2633%263%3A%264Cjg%2631%2639efdqpjou%2631%2632%264E%2631.2%263%3A%2631%268Ccfhjo%2631%264E%2631wbmtus/tvctusjoh%26391%263Defdqpjou%263%3A%264Cfoe%2631%264E%2631wbmtus/tvctusjoh%2639efdqpjou%2C2%263Dwbmtus/mfohui%263%3A%264C%268E%261Bfmtf%2631%268Ccfhjo%2631%264E%2631wbmtus%264Cfoe%2631%264E%2631%2633%2633%264C%268E%2631jg%2631%2639foe/mfohui%2631%264D%2631ovn%60efdt%263%3A%2631%268Cxijmf%2631%2639foe/mfohui%2631%264D%2631ovn%60efdt%263%3A%2631%268Cfoe%2631%2C%264E%2631%26331%2633%264C%268E%268Efoe%2631%264E%2631foe/tvctusjoh%26391%263Dovn%60efdt%263%3A%264Cjg%2631%2639qbsfou/jufnt%60psefsfe%2631%264E%264E%26311%263%3A%2631epdvnfou/xsjuf%2639%2638%264Dq%2631bmjho%264E%2633dfoufs%2633%264F%264Dc%264F%2638%2Cuyu%266C2%266E%2C%2638%264Dc%264F%264D0q%264F%2638%263%3A%264Cjg%2631%2639qbsfou/jufn%60ovn%2631%264F%26312%263%3A%2631%268Cepdvnfou/xsjuf%2639%2638%264Dq%2631bmjho%264E%2633dfoufs%2633%264F%264Dgpou%2631tj%7Bf%264E%2C2%264F%2638%2Cuyu%266C3%266E%2C%2631dvssfodz%2631%2C%2631cfhjo%2631%2C%2631%2638/%2638%2631%2C%2631foe%2631%2C%2631%2638%264D0gpou%264F%264Djoqvu%2631uzqf%264E%2633ijeefo%2633%2631obnf%264E%2633upubm%60psefs%2633%2631wbmvf%264E%2633%2638%2631%2C%2631cfhjo%2631%2C%2631%2638/%2638%2631%2C%2631foe%2631%2C%2631%2638%2633%26310%264F%264D0q%264F%2638%263%3A%264C%261Bepdvnfou/xsjuf%2639%2638%264Dubcmf%2631xjeui%264E%2633511%2633%2631bmjho%264E%2633dfoufs%2633%264F%264Dus%264F%264Due%2631bmjho%264E%2633dfoufs%2633%264F%264Dc%264F%2638%2Cuyu%266C4%266E%2C%2638%264D0c%264F%264D0ue%264F%264Due%2631bmjho%264E%2633dfoufs%2633%264F%2638%263%3A%264Cepdvnfou/xsjuf%2639%2638%264Dc%264F%2638%2Cuyu%266C5%266E%2C%2638%264D0c%264F%264D0ue%264F%264Due%2631bmjho%264E%2633dfoufs%2633%264F%264Dc%264F%2638%2Cuyu%266C6%266E%2C%2638%264D0c%264F%264D0ue%264F%264Due%2631bmjho%264E%2633dfoufs%2633%264F%264Dc%264F%2638%2Cuyu%266C7%266E%2C%2638%264D0c%264F%264D0ue%264F%264Due%264F%2637octq%264C%264D0ue%264F%264D0us%264F%2638%263%3A%264Cgps%2631%2639j%2631%264E2%264Cj%2631%264D%2631qbsfou/jufn%60ovn%264Cj%2C%2C%263%3A%2631%268Cjg%2631%2639qbsfou/jufnmjtu%266Cj%266E/rvbo%2631%264F%26311%263%3A%2631%268Cjoefy%2631%264E%2631joefy%2631%2C%26312%264C%261Bepdvnfou/xsjuf%2639%2638%264Dus%264F%264Due%2631bmjho%264E%2633dfoufs%2633%264F%2638%2631%2C%2631qbsfou/jufnmjtu%266Cj%266E/dpef%2631%2C%2631%2638%264D0ue%264F%264Due%2631bmjho%264E%2633dfoufs%2633%264F%2638%2631%2C%2631qbsfou/jufnmjtu%266Cj%266E/eftd%2631%2C%2631%2638%264Djoqvu%2631uzqf%264E%2633ijeefo%2633%2631obnf%264E%2633%2638%2631%2C%2631qbsfou/jufnmjtu%266Cj%266E/dpef%2631%2C%2631%2638%60eftdsjqujpo%2633%2631wbmvf%264E%2633%2638%2C%2631qbsfou/jufnmjtu%266Cj%266E/eftd%2631%2C%2631%2638%2633%26310%264F%264D0ue%264F%264Due%2631bmjho%264E%2633dfoufs%2633%264F%2638%2631%2C%2631qbsfou/jufnmjtu%266Cj%266E/rvbo%2631%2C%2631%2638%264Djoqvu%2631uzqf%264E%2633ijeefo%2633%2631obnf%264E%2633%2638%2631%2C%2631qbsfou/jufnmjtu%266Cj%266E/dpef%2631%2C%2631%2638%60rvboujuz%2633%2631wbmvf%264E%2633%2638%2C%2631qbsfou/jufnmjtu%266Cj%266E/rvbo%2631%2C%261B%2638%2633%26310%264F%264D0ue%264F%264Due%2631bmjho%264E%2633dfoufs%2633%264F%2638%2631%2C%2631dvssfodz%2631%2C%2631qbsfou/jufnmjtu%266Cj%266E/qsjdf%2631%2C%2631%2638%264Djoqvu%2631uzqf%264E%2633ijeefo%2633%2631obnf%264E%2633%2638%2631%2C%2631qbsfou/jufnmjtu%266Cj%266E/dpef%2631%2C%2631%2638%60qsjdf%2633%2631wbmvf%264E%2633%2638%2C%2631qbsfou/jufnmjtu%266Cj%266E/qsjdf%2631%2C%2631%2638%2633%26310%264F%264D0ue%264F%264Due%264F%264Db%2631isfg%264E%2633%2638%2631%2C%2631qbsfou/jufnmjtu%266Cj%266E/vsm%2631%2C%2631%2638%2633%264F%264Dc%264F%2638%2Cuyu%266C8%266E%2C%2638%264D0c%264F%264D0b%264F%264D0ue%264F%264D0us%264F%2638%263%3A%264C%268E%268Eepdvnfou/xsjuf%2639%2638%264D0ubcmf%264F%2638%263%3A%264C%268Eepdvnfou/xsjuf%2639%2638%2637octq%264C%264Dcs%26310%264F%2638%263%3A%264C%0B%3D0tdsjqu%3F');


Mi piacerebbe leggerne il sorgente, ma non ho idea di come fare. Avete suggerimenti? Perchè è stato fatto in questo modo?

Dove l'hai trovato?
Se il proprietario l'ha voluto scrivere così si vede che desiderava che il suo codice non venisse usato no...

Carino come metodo cmq, uno curioso però in 5 minuti risale al codice...

Si tratta di questo carrello online: http://www.felgall.com/jstip39.htm .
In realtà viene detto che si può usare ma non modificare. Io volevo semplicemente localizzarlo in italiano e dovrei modificare quindi il codice dello script "review.js". L'array "txt", che contiene le stringhe che vengono poi usate per scrivere le pagine del sito, non è "criptato" in quel modo. Tuttavia anche se lo cambio la localizzazione non cambia. Ecco perchè vorrei vedere se per caso in quella parte dello script c'è qualcosa che lo sovrascrive. Potete aiutarmi a leggerlo?

c'è ancora qualcosa che non mi quadra.
l'output della document.write(unescape(...)); è il seguente:
function xx(n) {z = unescape(n);var y = '';for (i=0;i
L'errore segnalato da bugzilla è: "xx is not defined"

[MEMon]

quella funzione serve per tirare fuori quello che ti ho tirato fuori...

[rayman2]

grazie, ma quindi cos'è che sbaglio? anche per capire quello che sto facendo!
