//! Key management module for protocol encryption/decryption
//!
//! Aligned with ProtoPirate's keys.c (KIA_KEY1..4, get_kia_mf_key, etc.).
//! Keys are loaded from the embedded keystore blob in `crate::keystore` at startup,
//! matching the standard encrypted + VAG raw keystore data.
//! Keys are loaded from the embedded keystore blob in `crate::keystore` at startup
//! via `load_keystore_from_embedded()`, which parses the blob from
//! `keystore::embedded::KEYSTORE_BLOB` and populates:
//!
//! - **KIA**: type 10 → kia_mf_key, 11 → kia_v6_a_key, 12 → kia_v6_b_key, 13 → kia_v5_key
//! - **Star Line**: type 20 → star_line_mf_key
//! - **VAG**: raw 64 bytes after "VAG " tag = 4 × 16-byte AUT64 packed keys (index in byte 0 of each)
//!
//! VAG protocol looks up keys by `get_vag_key((key_index + 1) as u8)` (index 1, 2, 3).
//! KIA V5 uses `get_kia_v5_key()`, KIA V6 uses `get_kia_v6_keystore_a()` / `get_kia_v6_keystore_b()`.
