strong encryption for ZIP-Files

Post by Markus » Sun Jun 29, 2008 6:20 pm

Hi Barry,
I have to store my backup-files in an rather unsafe location so I´m looking for a strong encryption for the ZIP-Files. As far as I see AISbackup is using the standard-ZIP-encryption which is rather weak and can be broken quite easily by a brute-force-attack or a known-plaintext-attack.

Would it be possible to use AES on the ZIP-Files as some other ZIP-programs do already?

Regards

Markus

AES Encryption

Post by Barry » Sun Jun 29, 2008 7:30 pm

Hi Markus

There is an intention to use AES encryption with AISBackup, however AISBackup will probably move to a proprietary format (similar to zip) for the backup files so that the backup data is no longer made to fit the zip file specification.

What I have done for my own backups is format disks using Truecrypt as this offers fast AES encryption at device level rather within the backup itself. I also like the fact that the Truecrypt software is portable and is stored in a non-encrypted part of the same disk volume so that the backup can be taken to another computer that is not running Truecrypt.

Also look at Traveler Mode in the menu system for making encrypted USB Flsh drives etc.

Hi Barry,

thanks for your reply. I´m looking forward for the new format an strong encryption.
I´m already using Truecrypt for some backup-partitions on external disks, but in this special case I can´t use a Truecrypt-Container because I need single files and the file-size is limited.

Package and encrypt

Hi Markus

If you want to encrypt a backup to send to someone else you could use the Manage Backup / Package and Encrypt option, this uses AES-128 bit or AES-256 bit encryption. This will copy (not move) the whole backup in one .aes file.

Hi Barry,

this would be good if the Backup-Files could be encrypted one by one. The actual Backup-Size is around 12 GB, so the function complains about the size.

I still can't figure this out. is there a way to encrypt the back up files individually?
