FIPS 180-4 Standard for Digital Signature

I've been tasked with locating software that allows us to digital sign documents to submit to various agencies.  I've been unable to determine if Adobe's product meets the FIPS 180-4 standard that we need to comply with.  I did see in the standards information it meets the 186-4.  Can anyone provide any references on the 180-4 standard in regards to Adobe's software complying?  I apologize if this is a stupid question.  However, I am not very familiar with either standard and want to make sure I can provide a recommendation based information I can cite.  Thanks.
