//! Public-key infrastructure: certificate parsing, signer-identity extraction,
//! expiry math, ETSI Trust Service List handling, and chain validation.
//!
//! Certificate and CMS parsing use the RustCrypto `x509-cert` / `cms` crates;
//! per-link chain signatures are checked with `x509-verify`. The submodules are
//! private; the curated public surface is re-exported here.
