Padding

[bored-engineer]

A weird issue has come up recently where the padding seems to be messed up.

To replicate:
var me = new Blowfish("me");
var Data = me.encrypt("stuff");
alert(me.decrypt(Data));

It should alert "stuff" but instead its "stuff000"

I wrote this simple addon for the decrypt function to fix it:

//Patch by me to remove trailing zeros
returndata = this.unescape(dec);
revertext = returndata.split("").reverse();
for(i=0;i<8;i++){
  if(revertext[i] == "0"){
    delete revertext[i];
  }
}
returndata = revertext.reverse().join("");*
return returndata;

but it is obviously not ideal.

I just checked this against the "marcelgreter" branch (https://github.com/drench/blowfish.js/tree/marcelgreter) and that version does not have the padding problem. Give that version a try if you don't need compatibility with Perl's Crypt::Blowfish.
