Sign Drawings
Digital signatures maintain authenticity and provide a safe environment for
sending and receiving data. You can work on collaborative projects, transmit
files over the Internet, and help guarantee that the files have not been
altered.
Digital IDs use two keys — a public key, which anyone can use to validate a
digital signature, and a private key, which is known only by the originator of
the digital ID. The private key is used to create the digital signature. To learn
more about digital IDs, digital signatures, and public and private keys, search
the Internet for these terms.
You can attach signatures to files that are compatible with the AutoCAD 2004
and AutoCAD 2000 drawing-file formats, including files generated by the
eTransmit feature. To attach a signature to multiple files at once, or to attach
a signature to a file compatible with the AutoCAD 2000 drawing-file format,
see the “Attach Digital Signatures Dialog Box” in the Command Reference.
Overview of Digital Signatures
With a digital signature, you can collaborate more easily with others on
projects. Recipients of drawings are provided with reliable information about
who created a set of drawings and whether they were modified since they
were digitally signed.
