How to programmatically sign test data?

[zilla]

Hello LV fans,

I’m looking for some ideas/methods to programmatically apply a digital signature to my test data. Currently I write to Excel, using ActiveX, then print and manually sign each data sheet. I’m open to new ideas to improve this process.

thanks

I've never done this, but... PDF995 gives you a way of creating PDFs programmatically. They also advertise a digital signature function in the same software package although it isn't clear if this can also be controlled programmatically.

Some details here:

Hi zilla,

What are you using to digitally sign the documents?  If there's a DLL that can do this, you can call that from LabVIEW.  Otherwise, you may be able to call any executable using the System Exec.vi.

Hello Jared,

I'm not digitally signing my test reports now. I have to print them out, sign them, then have them scanned in for a permanent record. My VI pulls up the users' log in ID from the computer, and puts the users' name on the report. I'd like to take the process one step further and have each report digitally signed. Perhaps using MS Excel's digitial signature, or I could have the reports saved as pdf's and use Adobe Acrobat 8.0.

thanks..

Hi zilla,

Are you trying to append an image of a signature, or do you want to apply a digital signature that can be check by your computer?  If Excel can do this, I would look into whether this can be done using ActiveX.  If it can, then you can use ActiveX from LabVIEW to apply the signature.

I would like to apply a digital signature. This can be done using Excel, however when searching for terms like ActiveX, signature, digital etc. I only come up with methods to digitally sign macros.
