//! Backends for checking X.509 certificate trust against a
//! [`CertificateTrustPolicy`](super::CertificateTrustPolicy).
//!
//! The active backend mirrors the cryptography backend selected for
//! `c2pa-raw-crypto`.

// The OpenSSL trust backend is only used when `openssl` is enabled and
// `rust_native_crypto` is not; when both are enabled the dispatch in
// `certificate_trust_policy.rs` prefers `rust_native_crypto` (mirroring
// `c2pa-raw-crypto`). Gating the module to match that dispatch avoids compiling
// it as dead code.
#[cfg(all(
    feature = "openssl",
    not(all(feature = "rust_native_crypto", target_arch = "wasm32"))
))]
