1. Summary
The NIST Digital Manufacturing Certificate (DMC) Toolkit is a toolkit designed specifically to provide certification—digital signature using software and hardware certificates and verification—of manufacturing related data. The DMC toolkit supports signature and validation of data in the following formats: ISO 10303–21 (STEP) [1], ISO 6983 (G-code) [2], ISO 32000 (PDF) [3] and 14739 (PRC, a.k.a. 3D PDF) [4], and Quality Information Framework (QIF) [5]. The project offers the Toolkit as a .NET API (written in C#), a command-line tool, and a fully-functional demonstration application.

3. Methods
This software provides source-code, an executable file with graphical user-interface, and a command-line tool for digitally signing manufacturing-related data. The user of this software may use any of the supplied options that best meet the user’s need to digitally sign data. A general overview of the methodology implemented in the toolkit is available in Ref. [6]. More information and details on the specific use of each method is available at https://doi.org/10.18434/T4P30K.
Biography
