The default value for the Archive protection parameter is “Disabled”. This option is not available when editing the existing task or when creating a new task specifying the existing archive.
In order to protect your archive from unauthorized access, select the Set password for the archive check box, then type your password in the Enter the password field; and, finally re-type it in the Confirm the password field. Note that the password is case-sensitive.
The created archive can be protected either with just a password or enhanced with the Advanced Encryption Standard (AES) 128/192/256-bit key encryption algorithm. Iа you select Do not encrypt, your archive will be protected with the password only. If you would like to use the encryption, select one of the following: AES 128, AES 192 or AES 256.
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.
