A-PDF 密碼安全是一個桌面實用程式，允許您更改現有 Acrobat PDF 檔的密碼安全性。這意味著您可以使用 128 位元加密保護 PDF 檔案或刪除密碼保護。它可以處理單個或批處理文檔。另一個方便的功能包括密碼池和熱目錄。 使用 A-PDF 密碼安全設定，如果需要密碼才能打開和/或有存取限制，您可以設定 PDF 檔。例如，允許或不允許列印、複製內容或更改檔等。您可以同時修改中繼資料，包括作者、標題、主題和關鍵字。A-PDF 密碼安全甚至支援禁用/啟用過期功能。 A-PDF 密碼安全適用於未加密或加密的 PDF 檔，不需要 Adobe Acrobat。 密碼池：如果您需要用一個密碼對一批 PDF 檔進行不安全，可以特別使用密碼池。A-PDF 密碼安全部門將一個嘗試密碼，而不是手動輸入密碼。 熱目錄：您可以設置一個受監視的目錄，其中寫入該目錄的所有檔將在保存時進行加密。原始檔也可以移動到備份目錄。所有操作都將記錄在日誌檔中。
