Nothing. That's the nature of physical signatures. A physical signature binds tightly to the individual (handwriting being hard to forge), but loosely to the document. A digital signature binds loosely to the individual (certificate repudiation being pretty easy), but tightly to the document. This is one of the reasons why I generally dislike the way the word "signature" gets abused in these discussions. Comparisons to physical signatures inevitably arise, and the two of them seem quite a bit more dissimilar than alike. _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
