As I understand the paradigm, the point of signing a document is to give the recipient some assurance that it came form someone with the private key. In theory, you could invert the algorightm used to generate the public key from the private key or exhaustively search for a signature that "works" but then you would have defeated the security concept. It is also supposed to be non-repudiable so the private key holder can't deny that he signed a given document if the signature is valid. So, you would essentially be forging someone else's signature if you could do what you want to do. > > Thanks and regards > > Gaurav Kumar Tyagi > Asst.
