Explanation needed for FIPS mode setting in Acrobat Reader DC

Question

I have seen a lot of older posts regarding an issue similar to this, but for some reason I cannot see the answers (though they were marked as successfully answered).

What I need is an explanation of how to tell, within Adobe Acrobat Reader DC, whether FIPS cryptography is turned on or off. We (U.S. Department of the Navy, Naval Sea Systems Command) are currently experiencing an issue whereby if they attempt to fill, sign, and then save a fillable, signable PDF form using Adobe Acrobat DC (the full version) we get an error message saying that "Document could not be saved. Use of non-FIPS cryptography is not permitted while in FIPS mode" (attachment with screencap). But if we do the same thing in Reader DC, it works just fine.

My question is, when the message says "while in FIPS mode" is that referring to the mode that Adobe is in, or the mode Windows is in? If it's Adobe, how can I see the setting in each of the to applications?

We are using Reader DC version 2021.001.20138 and Acrobat DC version 2020.013.20074.

Thank you.

Hi Tjdavid

Hope you are doing well and sorry for the trouble. As described you are getting the error 'Document could not be saved. Use of non-FIPS cryptography is not permitted while in FIPS mode'

Are you on a personal machine or IT managed work machine?
