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.
