SQLBackupAndFTP provides 2 encryption methods (Prof version only):
1. ZIP compatible.
It supports a simple password-based symmetric encryption. Note that it provides basic encryption only and is vulnerable to known-plaintext attacks. You can use built-in Windows compressor to open backups encrypted using ZIP compatible encryption method.
2. WinZip AES.
AES is a strong encryption standard adopted by the U.S. government. Built-in Windows compressor does not support AES files, so you have to use 7Zip (freeware) or WinZip 9.0 (or higher) to open backups encrypted using WinZip AES encryption method.
Also, note that backup files over 2 GB are zipped using Zip64 format.
Built-in Windows compressor does not support Zip64, so use 7Zip (freeware) or other archiver to uncompress it.
