ok, I have time for another comment.

From what I read only using an asymmetric cipher would be very slow.

The question is whether you need to the speed enough to warrant that extra code. The extra code increases development time, the probability of a bug, the probability of a security bug, debugging time and maintenance time.

From the customer's perspective: No. The tool will only be used on rare occasion, and the few seconds lost on those occasions won't matter.

From your perspective: Maybe. Will you be receiving data from many customers at the same time? often? From what you said, it doesn't like it.

Since you have to do it anyway, start with trying just the asymetric portion. If your needs aren't satisfied, then add the symetric bit.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
