The ear package provides a golang API for working with EAR (EAT Attesation Result), an EAT/JWT serialisation of the Attestation Result for Secure Interactions (AR4SI) information model.
A command line interface utility (arc) is also provided to create, verify and display EAR attestation result payloads. To install it:
go install github.com/veraison/ear/arc@latest
