Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.Embodiment described in following exemplary embodiment does not represent all embodiments consistent with the application.On the contrary, they only with as in appended claims describe in detail, the example of apparatus and method that some aspects of the application are consistent.
Only for describing the object of specific embodiment at term used in this application, and not intended to be limiting the application." one ", " described " and " being somebody's turn to do " of the singulative used in the application and appended claims is also intended to comprise most form, unless context clearly represents other implications.It is also understood that term "and/or" used herein refer to and comprise one or more project of listing be associated any or all may combine.
Term first, second, third, etc. may be adopted although should be appreciated that to describe various information in the application, these information should not be limited to these terms.These terms are only used for the information of same type to be distinguished from each other out.Such as, when not departing from the application's scope, the first information also can be called as the second information, and similarly, the second information also can be called as the first information.Depend on linguistic context, word as used in this " if " can be construed as into " ... time " or " when ... time " or " in response to determining ".
The application is by carrying out hash operations by the variable name of js file; thus reach the object that the code of js file is obscured; by carrying out packaging ciphering to the hashed result after obscuring; reduce the readability of the code of js file; increase the difficulty that bootlegger cracks js file and understands, thus achieve the copyright protection to js file.For being further described the application, provide the following example:
Please refer to Fig. 1, Fig. 1 is the process flow diagram of the method for in one embodiment of the present invention, code being carried out to confidential treatment, can be applied on server, comprise the steps:
Step 101, carries out hash operations by the variable name in the code of js file according to the action scope of js file, obtains the hashed result of js file.
Step 102, carries out packaging ciphering by the function in hashed result, obtains the character string after packaging ciphering.
In a step 101, the action scope of js file take function as boundary, and different functions has relatively independent action scope.Function inside can be stated and be accessed global variable, also can var (use var key word, the parameter of function is also local variable), but function external cannot access inner local variable.How by the action scope of js file, hash is carried out to code in embodiment for a more clear understanding of the present invention, carries out exemplary illustration with following code:
(function(){}
var car＝"hello"；
function add(num1,num2){
return num1+num2；
})()；
Above-mentioned code carries out the code after hash operations:
(function(){}
var a＝"hello"；
function d(a,b){
return a+b；
})()；
Wherein, in code after hash operations, first corresponding car of variable a, second corresponding num1 of variable a, therefore two places of above-mentioned action scope are present in the code of a variable after above-mentioned hash operations, a variable in add function covers a variable of outside, is therefore under two diverse values are present in different action scopes separately.In addition, because add function name has been replaced by d, the action scope due to add is present in closure action scope above, although function name is replaced, does not affect the normal logic of code, function performance and semantic not change.Therefore after above-mentioned hash operations, reach the object that js code is obscured, the readability of js code is reduced greatly, add the cost understood and reduce js code.
In a step 102, in one embodiment, the function in hashed result is carried out packaging ciphering and can adopt pack function and eval function.Eval function and the concrete function of eval function realize the embodiment of the present invention and do not describe in detail.
The embodiment of the present invention by the code after the packing of eval function encrypting is:
eval(function(p,a,c,k,e,r){e＝String；if('0'.replace(0,e)＝＝0){while(c--)r[e(c)]＝k[c]；k＝[function(e){return
r[e]||e}]；e＝function(){return'[124-6]'}；c＝1}；while(c--)if(k[c])p＝p.replace(newRegExp('\\b'+e(c)+'\\b','g'),k[c])；return p}('24＝4||[]；(function(){2
1＝5.createElement("6")；1.src＝"//1.baidu.com/1.js？601fa469903febe1abec3479027feb76"；2
s＝5.getElementsByTagName("6")[0]；s.parentNode.insertBefore(1,s)})()；',[],7,'|hm|var||_hmt|document|script'.split('|'),0,{}))。
From step 101 to step 102; by the variable name of js file is carried out hash operations; thus reach the object that the code of js file is obscured; by carrying out packaging ciphering to the hashed result after obscuring; reduce the readability of the code of js file; increase the difficulty that bootlegger cracks js file and understands, thus achieve the copyright protection to js file.
Refer to Fig. 2, Fig. 2 is the process flow diagram of the method for in another embodiment of the present invention, code being carried out to confidential treatment, and the present embodiment can be applied on the server, comprises the steps:
Step 201, carries out compression pre-service to the code of js file.
Step 202, determines the letter hass table variable name in the code of js file being carried out to hash operations.
Step 203, the variable name in the code of js file is carried out hash operations by the action scope according to letter hass table and js file, obtains the hashed result of js file.
Step 204, carries out packaging ciphering by the function in hashed result, obtains the character string after packaging ciphering.
Step 205, determines the mapping relations table preset of the character string after packaging ciphering.
Step 206, obscures the character string after packaging ciphering according to mapping relations table.
Step 207, is stored in the ASCII respective value of the character string after packaging ciphering in picture file in the mode of pixel value.
In above-mentioned steps 201, can by the space in js file, newline, annotation are identified and deleted, thus the form of the code of js file can be made more compact, save the storage space of js file further.
In above-mentioned steps 202 and step 203, in one embodiment, letter hass table can be generated by hash function, by letter hass table, variable name in code or method name are replaced, thus make js code be not easy to be understood, due to the nonreversibility of hash, the decompiling of variable in js code therefore effectively can be prevented by step 202 and step 203.Concrete how the variable name in the code of js file carried out hash operations according to the action scope of letter hass table and js file, refer to the description of above-mentioned steps 101, be not described in detail in this.
In above-mentioned steps 204, can by eval method to js code packaging ciphering.
Such as following js code:
var_hmt＝_hmt||[]；
(function(){
var hm＝document.createElement("script")；
hm.src＝"//hm.baidu.com/hm.js？601fa469903febe1abec3479027feb76"；
var s＝document.getElementsByTagName("script")[0]；
s.parentNode.insertBefore(hm,s)；
})()；
Js code after step 204 packaging ciphering is:
eval(function(p,a,c,k,e,r){e＝String；if('0'.replace(0,e)＝＝0){while(c--)r[e(c)]＝k[c]；k＝[function(e){return
r[e]||e}]；e＝function(){return'[124-6]'}；c＝1}；while(c--)if(k[c])p＝p.replace(newRegExp('\\b'+e(c)+'\\b','g'),k[c])；return p}('24＝4||[]；(function(){2
1＝5.createElement("6")；1.src＝"//1.baidu.com/1.js？601fa469903febe1abec3479027feb76"；2
s＝5.getElementsByTagName("6")[0]；s.parentNode.insertBefore(1,s)})()；',[],7,'|hm|var||_hmt|document|script'.split('|'),0,{}))。
In above-mentioned steps 205 and step 206, by the mapping relations table preset, the character string after packaging ciphering is obscured, the code after encryption can be made more not easily to be cracked, when needing to identify the code after step 206 is obscured, can according to the mapping relations table preset by the code reverse after packaging ciphering, have the mapping relations table of reversible relation by this, what can increase js code further cracks difficulty.In one embodiment, the mapping relations table preset such as, by corresponding for character a character m (a->m), " corresponding % ("->%) etc., as long as can by the mutual corresponding relation between mapping relations table explicit character.
In above-mentioned steps 207, because js code is character, and each character has an ASCII respective value, the scope of ASCII respective value is 0 to 255, therefore, is kept in a pictures by the js code after above-mentioned steps 206 can process by this step in the mode of pixel value, when needs run js file, by each pixel value on traversal picture, particularly, can by the js code of charCodeAt function acquisition place after the process of the above-mentioned pixel value be kept in picture.
From step 201 to step 207; the present embodiment is except having on the basis of above-mentioned Advantageous Effects embodiment illustrated in fig. 1; also obscured to the character string after packaging ciphering by Quadratic Map relation (default mapping relations table); the code after encryption can be made more not easily to be cracked; by js code is preserved in the mode of picture; conceal js file; increase the difficulty that bootlegger obtains js file further, thus achieve the copyright protection to js file.
When needing the js file after running through said method process, can by the js file of reversible process operation after said method process, such as, by UNPACK function, the js code after pack function packaging ciphering is decrypted, can be included in the file of ciphered compressed and carries out decoding operation.The code of string representation directly can be run by eval function.Due to environment when eval function has become js running paper, the logic therefore for hiding js code provides host environment.
