Thanks for the presentations resources.I downloaded latest rhino version
and load crypto file into the rhino and nashorn seperately and run the
encrypt method.
In rhino when i repeatedly run the encrypt method in the consolde I got
this results

js> encrypt();
54
js> encrypt();
33
js> encrypt();
27
js> encrypt();
46
js> encrypt();
28
js> encrypt();
25
js> encrypt();
35
js> encrypt();
28
js> encrypt();
27
js> encrypt();
23
js> encrypt();
26
js> encrypt();
17
js> encrypt();
24
js> encrypt();
23
js> encrypt();
26

And when I run it in the nashorn

jjs> encrypt();
153
jjs> encrypt();
125
jjs> encrypt();
118
jjs> encrypt();
114
jjs> encrypt();
139
jjs> encrypt();
53
jjs> encrypt();
51
jjs> encrypt();
56
jjs> encrypt();
49
jjs> encrypt();
49
jjs> encrypt();
47
jjs> encrypt();
72
jjs> encrypt();
46
jjs> encrypt();
36
jjs> encrypt();
25
jjs> encrypt();
27
jjs> encrypt();
36
jjs> encrypt();
31
jjs> encrypt();
26
jjs> encrypt();
25
jjs> encrypt();
24
jjs> encrypt();
25
jjs> encrypt();
33
jjs> encrypt();
40
jjs> encrypt();
27
jjs> encrypt();
27
jjs> encrypt();
26
jjs> encrypt();
103
jjs> encrypt();
134
jjs> encrypt();
40
jjs> encrypt();
23
jjs> encrypt();
26
jjs> encrypt();
27
jjs> encrypt();
26
jjs> encrypt();
28
jjs> encrypt();
24

I have got this variate results.I have attach the crypto file.Any idea is
this why this varying?
