Javascript脚本实现静态网页加密

2007-9-7 作者:黑基 网友评论 0 条 点击进入论坛

  前两天看见有人问静态网页加密问题,就写了这个代码

  思路:

  加密时:先把用户的密钥A用md5加密为B,然后用B异或源文件S0得到目标文件S1,把S1存入js变量中。

  解密时:询问密钥,然后操作同加密。

  因为用了md5,个人认为没有密钥的时候是无法破解的(暴力除外)

  大家试用一下哈哈:

  源代码如下:

  ";

  t2.value=strOut;

  }

  function runCode()

  function addSlash(str)

  function XOR(strV,strPass){

  var intPassLength=strPass.length;

  var re="";

  for(var i=0;i

  return(re);

  }

  function performPage(strPass)

  //**********如果需要自动记住密码,请将下面的注释改成代码

  /*

  var pass=document.cookie.match(/password=([^;]+)/i);

  if(pass)

  */

  //*************

  strAskPass=" ";

  strAskPass+="Password:";

  strAskPass+="

  ";

  document.write(strAskPass);

  }

  var STR =

  {

  hexcase : 0, /* hex output format. 0 - lowercase; 1 - uppercase */

  b64pad : "", /* base-64 pad character. "=" for strict RFC compliance */

  chrsz : 8, /* bits per input character. 8 - ASCII; 16 - Unicode */

  b64_hmac_md5:

  function(key, data) { return binl2b64(core_hmac_md5(key, data)); },

  b64_md5:

  function(s){ return binl2b64(core_md5(str2binl(s), s.length * this.chrsz));},

  binl2b64:

  function(binarray){

  var tab = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";

  var str = "";

  for(var i = 0; i < binarray.length * 4; i += 3)

  {

  var triplet = (((binarray[i >> 2] >> 8 * ( i %4)) & 0xFF) << 16)

  | (((binarray[i+1 >> 2] >> 8 * ((i+1)%4)) & 0xFF) << 8 )

  | ((binarray[i+2 >> 2] >> 8 * ((i+2)%4)) & 0xFF);

  for(var j = 0; j < 4; j++)

  {

  if(i * 8 + j * 6 > binarray.length * 32) str += this.b64pad;

  else str += tab.charAt((triplet >> 6*(3-j)) & 0x3F);

  }

  }

  return str;

  },

  binl2hex:

  function(binarray){

  var hex_tab = this.hexcase ? "0123456789ABCDEF" : "0123456789abcdef";

  var str = "";

  for(var i = 0; i < binarray.length * 4; i++)

  {

  str += hex_tab.charAt((binarray[i>>2] >> ((i%4)*8+4)) & 0xF) +

  hex_tab.charAt((binarray[i>>2] >> ((i%4)*8 )) & 0xF);

  }

  return str;

  },

  binl2str:

  function(bin){

  var str = "";

  var mask = (1 << this.chrsz) - 1;

  for(var i = 0; i < bin.length * 32; i += this.chrsz)

  str += String.fromCharCode((bin[i>>5] >>> (i % 32)) & mask);

  return str;

  },

  bit_rol:

  function(num, cnt){return (num << cnt) | (num >>> (32 - cnt));},

  core_hmac_md5:

  function(key, data){

  var bkey = str2binl(key);

  if(bkey.length > 16) bkey = core_md5(bkey, key.length * this.chrsz);

  var ipad = Array(16), opad = Array(16);

  for(var i = 0; i < 16; i++)

  {

  ipad[i] = bkey[i] ^ 0x36363636;

  opad[i] = bkey[i] ^ 0x5C5C5C5C;

  }

  var hash = core_md5(ipad.concat(str2binl(data)), 512 + data.length * this.chrsz);

  return core_md5(opad.concat(hash), 512 + 128);

  },

  core_md5:

  function(x, len){

  /* append padding */

  x[len >> 5] |= 0x80 << ((len) % 32);

  x[(((len + 64) >>> 9) << 4) + 14] = len;
