Digital signatures provide an electronic means of validating (verifying the authenticity of) signatures that are attached to drawing files.
A digital signature identifies an individual or an organization through a digital ID (certificate), and enables you to validate the file. Validating a file is especially important when you are working on collaborative projects or transmitting files over the Internet. You can validate a digital signature in either the program or Windows Explorer.
Using the digital signatures feature, you can obtain the following information about signed files:
A digital signature is determined to be invalid for the following reasons:
When you receive a file that contains a digital signature, you can check whether the file was modified since it was signed, and other information.
When you receive a file that contains a digital signature from a certificate authority that is not recognized by your operating system, you may need to obtain the root certificate (the highest level of certificate in a certificate chain) before you can determine if the digital ID in the digital signature is valid.
You can add a comment and time stamp to your digital signature.
