About Fair Proposals digitally signed Certificates
The authenticity of Certificates generated by the Fair Proposals System and signed
by Fair Outcomes, Inc. as PDF documents may be validated by opening those PDF documents
in any PDF reader application that supports digital signature validation.
Some applications (including Adobe Acrobat Reader) may need you to preinstall the root
digital certificate from DigiCert, Inc..
