Thank you for the suggestion, it corresponds to the length of the encryption key actually. I've updated the documentation to include the info available here https://www.winzip.com/en/support/aes-encryption/#extra-data, see below.

Value 	Strength
0x01 	128-bit encryption key
0x02 	192-bit encryption key
0x03 	256-bit encryption key
