Identity Credential
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
身分憑證 API 提供可安全儲存使用者身分文件的介面。這些 API 會與 credstore 系統服務通訊，而該服務會使用身分憑證 HAL 與安全硬體通訊。
系統會透過 IIdentityCredentialStore 存取身分憑證 HAL，該函式庫提供可安全儲存使用者身分文件的介面。在可行範圍內，請盡量讓與憑證驗證裝置與簽發機構 (IA) 通訊的訊息格式規格和語意用語超出這個 HAL 的範圍。它會提供安全儲存空間介面，但需要憑證專屬的 Android 應用程式，才能實作適合特定憑證類型的呈現和驗證通訊協定和程序。
