3.4.1.1
Archive protection
This option is effective for Windows and Linux operating systems and bootable media.
This option is effective for both disk-level and file-level backup.
The preset is:
Disabled.
To protect the archive from unauthorized access
1.
Select the
Set password for the archive
check box.
2.
In the
Enter the password
field, type a password.
3.
In the
Confirm the password
field, re-type the password.
4.
Select one of the following:
Do not encrypt
– the archive will be protected with the password only
AES 128
– the archive will be encrypted using the Advanced Standard Encryption (AES)
algorithm with a 128-bit key
AES 192
– the archive will be encrypted using the AES algorithm with a 192-bit key
AES 256
– the archive will be encrypted using the AES algorithm with a 256-bit key.
5.

OK
.
The AES cryptographic algorithm operates in the Cipher-block chaining (CBC) mode and uses a
randomly generated key with a user-defined size of 128, 192 or 256 bits. The larger the key size, the
longer it will take for the program to encrypt the archive and the more secure your data will be.
The encryption key is then encrypted with AES-256 using a SHA-256 hash of the password as a key.
The password itself is not stored anywhere on the disk or in the backup file; the password hash is
used for verification purposes. With this two-level security, the backup data is protected from any
unauthorized access, but recovering a lost password is not possible.
