John the Ripper doesn't identify hash

Question

I have a ZIP file of my gallery that contains images and videos which is over 5GB in size. I forgot the password for that ZIP file now I'm trying to crack it to extract files from there. I tried using JTR 1.9.0 Jumbo and Hashcat to crack it. I can run zip2john filename.zip > myzip.hash without problem, it takes 5 minutes to generate hash file, but at the end I get hash file which is like: filename.zip:$pkzip2$3*1*1*0*8*0*3c71*b0ef**1*0*8*0*dc4b*b0f0**2*0*0*e3a1*cb05a6ba*49*50*8*0*cb05*b142**$/pkzip2$ and continues with some contents of zip file (3 image file name with the folder it is in).

Whenever I run I get:

john myzip.hash
Using default input encoding: UTF-8
No password hashes loaded (see FAQ)

I even tried specifying format using --format=pkzip option, and there is no pkzip2 format so I only used pkzip.

I managed to start cracking process with ZipRipper but it was taking 20 days crack to be completed, so I was just asking is there way to fix that problem No password hashes loaded (see FAQ) and specify john the ripper that it is 4 char password with [a-zA-Z1-9] condition matching for all chars.

Hashcat also doesn't recognize this format, -m 17220 was what I just used.

Also, I'm using Windows 11.

Answer 1

After a long effort, I managed to crack it with ZipRipper. As I knew the password was 4 characters long and matched [a-zA-Z\d]{4} RegEx, I wrote a Python script to generate a custom wordlist because there wasn't one for my case, and chose a custom wordlist option in ZipRipper. Even though there were 14M lines of Passwords, it cracked immediately.

Unfortunately, I can't advise if you don't know the length of the password and charsets.
