Update: I realize I'm doing sort of an apples-oranges thing talking about server-client relationships and signatures. Please ignore my brainfarting i.e, this node) until I manage to get my wits together and express myself more clearly.

Of course the signature is paired with the message. But the logic that says "This signature matches that document" can't be on the client side, or it can be faked. That's why I suggested something like a database connection to verify authenticity. It's the digital equivalent of my bank calling me up and saying "Hey, did you write a cheque for $100 to the EFF?"

Rule #1 of any client-server based encryption work or security-related programming: Don't trust the client.

Title:
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.
