mailrs-arc

v3.0.0crates.io· Rust

RFC 8617 Authenticated Received Chain (ARC) — header parsing, chain extraction, and signature verification + sealing. ARC extends DKIM/SPF/DMARC across forwarders by chaining per-hop authentication results inside cryptographically-sealed header sets. v3 cuts RSA crypto over to aws-lc-rs via mailrs-dkim 3.0 for ~3× faster sign.
