Symmetric encryption - options?

I have answered this question so many times that I'm just going to refer
you to what I wrote on it several years ago:

(You will need to use Firefox or Chrome; IE doesn't support XHTML.  The
math looks best in Firefox.)

I would suggest putting on the brakes, taking a deep breath, and
explaining precisely you're trying to achieve.  My guess is you're
making this a *lot* harder than it has to be.

Speed kills.  Slow down, take a breath.  There are people here who can
help, but before we can help we need to know exactly what problem you
face.  :)
