pub const RFC9421_REQUIRED_COMPONENTS: &[&str];Expand description
Minimum RFC 9421 covered-component set every compliant verifier should enforce for POST requests.
@method and @target-uri together bind the signature to one
concrete resource; content-digest chains the signature to the
request body so a captured signature cannot be replayed against a
different payload. RFC 9421 §7.2.1 (“Choosing Signature Components”)
recommends exactly this triple for POST requests carrying a body,
and every mainstream Fediverse implementation we have seen on the
wire includes at least these three components.
