4.2.4 Encrypted File System
On this page, you can manage encrypted disk volumes on the NAS. Each encrypted disk
volume is locked by a particular key. The encrypted volume can be unlocked by the
following methods:
Encryption Password: Enter the encryption password to unlock the disk volume. The
default password is "admin". The password must be 8-16 characters long. Symbols
(! @ # $ % ^ & * ( )_+ = ?) are supported.
Encryption Key File: Upload the encryption file to the NAS to unlock the disk
volume. The key can be downloaded from the "Encryption Key Management" page
after the disk volume has been unlocked successfully.
Data encryption functions may be unavailable in accordance with legislative restrictions
of some countries (Russia, Belarus, Ukraine, Kazakhstan, Uzbekistan, etc.)

Da ta E nc ry ption on the NAS
NAS disk volumes can be encrypted using 256-bit AES encryption to provide data breach
protection. Encrypted disk volumes can only be mounted for normal read/write access
with the authorized password. Encryption protects confidential data from unauthorized
access even if the hard drives or the entire NAS were stolen.
About AE S e nc ry ption:
In cryptography, the Advanced Encryption Standard (AES) is an encryption standard
adopted by the U.S. government. The standard comprises three block ciphers, AES-128,
AES-192 and AES-256 [… ]. Each AES cipher has a 128-bit block size, with key sizes of
128, 192 and 256 bits, respectively. The AES ciphers have been analyzed extensively
and are now used worldwide.
