Veraison's attestation result format, which was once described at this place, is now superseded by EAR.
If you need to ask questions about EAR, feel free to join this Zulip stream.
If you want to use EAR in your codebase, the Veraison project provides three separate implementations:
veraison/ear, a Golang package that allows encoding, decoding, signing and verification of EAR payloads together with a CLI (arc) to create, verify and visualize EARs on the command line.C EAR, a C17 library that allows verification and partial decoding of EAR payloads.- Rust EAR, a Rust (2021 edition) library that allows verification and decoding of EAR payloads.
