First off thanks for this great application.
I am trying to figure out the level of encryption used with the backup option.
Looking over the code it would appear that when you select a backup format of zip with a password that no special switches other than -p and the password are put on the 7z command line. Based on this and if I am reading the 7z docs right you are only getting default encryption which is ZipCrypto and is rather weak.
I am pretty sure that selecting 7zip with a password will use AES256.
Am I reading this correctly? If so, could the software be updated so that the zip format uses AES256?
Thanks,
