前端参数用MD5加密

今天来讲一下如何用这个MD5来加密
第一步：
两种导入MD5.js
一种你可以到以下这个地址去引入MD5的js路径：https://www.bootcdn.cn/blueimp-md5/
另一种下面是md5的js,直接复制下去放到js文件里。亲测可用

  var hexcase = 0;  
var b64pad  = ""; 
var chrsz   = 8;  
function hex_md5(s){ return binl2hex(core_md5(str2binl(s), s.length * chrsz));}
function b64_md5(s){ return binl2b64(core_md5(str2binl(s), s.length * chrsz));}
function hex_hmac_md5(key, data) { return binl2hex(core_hmac_md5(key, data)); }
function b64_hmac_md5(key, data) { return binl2b64(core_hmac_md5(key, data)); }
function calcMD5(s){ return binl2hex(core_md5(str2binl(s), s.length * chrsz));}

function md5_vm_test()
{
  return hex_md5("abc") == "900150983cd24fb0d6963f7d28e17f72";
}

function core_md5(x, len)
{

  x[len >> 5] |= 0x80 <<((len) % 32);
  x[(((len + 64) >>> 9) <<4) + 14] = len;
  var a =  1732584193;
  var b = -271733879;
  var c = -1732584194;
  var d =  271733878;
  for(var i = 0; i  16) bkey = core_md5(bkey, key.length * 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 * chrsz);
  return core_md5(opad.concat(hash), 512 + 128);
}

function safe_add(x, y)
{
  var lsw = (x & 0xFFFF) + (y & 0xFFFF);
  var msw = (x >> 16) + (y >> 16) + (lsw >> 16);
  return (msw <<16) | (lsw & 0xFFFF);
}

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

function str2binl(str)
{
  var bin = Array();
  var mask = (1 <>5] |= (str.charCodeAt(i / chrsz) & mask) <<(i%32);
  return bin;
}

function binl2hex(binarray)
{
  var hex_tab = hexcase ? "0123456789ABCDEF" : "0123456789abcdef";
  var str = "";
  for(var i = 0; i >2] >> ((i%4)*8+4)) & 0xF) +
           hex_tab.charAt((binarray[i>>2] >> ((i%4)*8  )) & 0xF);
  }
  return str;
}

function binl2b64(binarray)
{
  var tab = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";
  var str = "";
  for(var i = 0; 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 += b64pad;
      else str += tab.charAt((triplet >> 6*(3-j)) & 0x3F);
    }
  }
  return str;
}
