KeyStore:热可替换的 keys 集合

Implementations§

Source§

impl KeyStore

Source

pub fn empty() -> Self

空 store(没有 keys 文件时)

Source

pub fn load(path: impl Into<PathBuf>) -> Result<Self, KeyStoreError>

从文件加载

Source

pub fn reload(&self) -> Result<(), KeyStoreError>

SIGHUP 热重载:用同一路径重新读文件

Source

pub fn verify(&self, plaintext: &str) -> Option<Arc<KeyRecord>>

明文校验:遍历所有未过期 key,匹配则返回 KeyRecord 快照

如果 key 设置了 allowed_machines 且本机不在白名单,会打 warn 日志并视为未匹配。 这样做法的代价:攻击者可以通过“能不能过“侧信道区分 key 是否存在 — 我们接受, 因为 plaintext 空间是 256 bit 随机 hex,侧信道没意义。

Source

pub fn is_configured(&self) -> bool

是否已加载 keys 文件(非 empty)

Source

pub fn path(&self) -> Option<&Path>

Source

pub fn len(&self) -> usize

Source

pub fn is_empty(&self) -> bool

Source

pub fn get_by_id(&self, id: &str) -> Option<Arc<KeyRecord>>

按 id 查询当前快照中的 key(不做 expiry / machine 校验,调用方自己做)

典型用法:MCP 在启动时 verify(plaintext) 拿到 id,后续每个请求用 get_by_id 取最新记录,这样 SIGHUP 重载 keys.json 后 scope / 限额 / expires_at 的变更能立刻生效(不用重启进程)。

返回 None 表示 id 在当前文件里不存在(被 remove_key 删掉了),调用方应 视为“key 已吊销“直接拒绝。

Source

pub fn ids(&self) -> Vec<String>

导出当前所有 keys 的 id(用于调试 / 审计)
