Need help with cracking pkzip
#1
Hello, I am a beginner in CTF's so I am here to ask for help. I have a pkzip hash that needs to be decrypted. I have received 5 previous passwords of the user (they are not in rockyou, they seem to be made with an algorithm that I am yet to discover). What mode can I use in hashcat that would make use of those given passwords.

The way passwords are built is:

If the number of letters is even the password has every other letter as lowercase, if it is not even then every other is an uppercase with set of numbers at the end. Since I am newbie with creating masks, would also appreciate if somebody could help me with those (link to an article where I could learn how to create those would be great!)
