Verifying a Digital Signature in a Drawing

Use the VerifySignature command to validate a digital signature attached to the current drawing.

The command uses a main and a secondary dialog box:

• The Digital Signature Verification dialog box lets you examine whether the digital signature is valid and the drawing file has not been altered since it was signed.
• The Digital Signature Details dialog box lets you view details about the digital signature:
  • File name and path
  • Signature status. Shows whether the digital signature is valid and the drawing file has not been altered since it was signed.
  • Digital ID details. Signer, Certificate issuer, validity period, signer's note, signature date, and more.

To verify a digital signature in a drawing:

1. Type VerifySignature at the command prompt.
2. In the Digital Signature Verification dialog box, use these options:
   • Display Base Signature. Displays information about the digital signature of the current drawing in the Digital Signature Details dialog box. This option is not available if the drawing is not signed.
   • Display Reference Signatures. Displays information about digital signatures of externally referenced drawings (References) attached to the current drawing in the Digital Signature Details dialog box. This option is not available if the nested References are not signed.
   • Ignore Reference Warnings. If this option is cleared, the Digital Signature Verification dialog box appears each time you attach an external drawing with a valid digital signature as Reference to the current drawing. The dialog box lets you examine status and information about the signature of the Reference drawing and probably signatures of nested Reference drawings.
3. Click OK.

  An icon at the right end of the Status Bar indicates whether a drawing file is signed. If the signature is valid, a stamp icon appears, and if it is invalid, the stamp icon appears stroked out. Click the icon to run the VerifySignature command.
