Hmmm, making those changes resulted in the not defined error:

ReferenceError: "window" is not defined.

So I just added some if statements: (~line 74)

if( typeof window === "undefined" )
  var window = {};
if( typeof navigator === "undefined" )
  var navigator = {}; 

if(j_lm && (navigator.appName == "Microsoft Internet Explorer")) {
  BigInteger.prototype.am = am2;
  dbits = 30;
}
else if(j_lm && (navigator.appName != "Netscape")) {
  BigInteger.prototype.am = am1;
  dbits = 26;
}
else { // Mozilla/Netscape seems to prefer am3
  BigInteger.prototype.am = am3;
  dbits = 28;
}

I had to make one more change as I was getting:

"../jsencrypt.js", line 3837: uncaught JavaScript runtime exception: ReferenceError: "ASN1" is not defined.

So I added "window" here: (~line 3837)

window.ASN1.prototype.getHexStringValue = function(){
    var hexString = this.toHexString();
    var offset = this.header * 2;
    var length = this.length * 2;
    return hexString.substr(offset,length);
};

This of course resulted in a few other errors. I added "window." to the Base64 and ASN1 objects below: (~line 3867)

RSAKey.prototype.parseKey = function(pem) {
    try{
        var reHex = /^\s*(?:[0-9A-Fa-f][0-9A-Fa-f]\s*)+$/;
        var der = reHex.test(pem) ? Hex.decode(pem) : window.Base64.unarmor(pem);
        var asn1 = window.ASN1.decode(der);

Finally, I ran this code before I did the load( 'jsencrypt' ) call:

console = { 
   error: function( stuff ) { print( stuff ) },
   warn:  function( stuff ) { print( stuff ) },
   info:  function( stuff ) { print( stuff ) },
   debug: function( stuff ) { print( stuff ) },
   log:   function( stuff ) { print( stuff ) }
}

I haven't tried decrypting yet, the thread keeps running out of memory. I'm pretty sure there is a meomory leak in rhino or something. I'll have to dig into that.

Oh, well I think i got it working... haven't fully tested yet, but it successfully loads.
I set

var window = {};
var navigator ={};

around line 73.
Then, it looks like the "ASN1.prototype.getHexStringValue" around line 3834 is outside the anonymous function its brothers are in. So, I move the closing }) (); to just after this block.

Darn.. I can't just fake it :)

We will need to patch the jsbn libraries from Tom Wu to fix this issue. It can probably be done if you just add a check if those variables exist before calling an object within them. Like this...

if(j_lm && navigator && (navigator.appName == "Microsoft Internet Explorer")) {
  BigInteger.prototype.am = am2;
  dbits = 30;
}
else if(j_lm && navigator && (navigator.appName != "Netscape")) {
  BigInteger.prototype.am = am1;
  dbits = 26;
}
else { // Mozilla/Netscape seems to prefer am3
  BigInteger.prototype.am = am3;
  dbits = 28;
}

I have not tried yet to encrypt/decrypt but my guess is that is working. Please tell me if it does, so that we can close this issue

Seems to work, closing this issue

Hey, sorry, this was on my list to checkout, but I haven't gotten to it yet. If I get a chance, I'll check it out, but I'm fine with closing this issue.
Thanks!!
