Frequently Asked Questions
How secure is the encryption used?▼
Kami menggunakan penyulitan AES (Advanced Encryption Standard) standard, bank dan kerajaan standard kriptografi yang sama bergantung harap untuk melindungi data sensitif.
What happens if I forget the password?▼
Fail menjadi tidak boleh dibaca secara kekal tanpanya. Kami tidak menyimpan salinan kata laluan atau dokumen anda, jadi tiada cara untuk kami memulihkannya untuk anda — simpannya di tempat yang selamat.
Does password protection also stop people from printing or copying?▼
Setting an open password requires anyone to enter it before they can view the file at all, which covers printing and copying too, since they can't access the content without opening it first.
Bolehkah saya mengalih keluar kata laluan itu kemudian jika saya tidak memerlukannya lagi?▼
Ya, gunakan Buka Kunci PDF dan masukkan kata laluan untuk menanggalkannya semula apabila fail tidak perlu disekat lagi.
Is my password sent anywhere while I'm setting it?▼
No, the encryption is applied entirely inside your browser, so the password you type never leaves your device.
