Help creating a mask
#1
Hi there! I’m new to this and running hashcat on a Mac. I’ve extracted hash from a Mac (SHA512) password and trying to figure out how to crack it using a combination of dictionary attack but with added rules for things I know about I know about the passwords. 

What I know is it has between 6 and 9 lower case letters, followed by (and ending with) the numbers 321

Could somebody give me an example script that’s I can paste into hashcat (replacing hash File and dictionary files with my own)

That would be great, thanks!

What youre asking for is really basic, and you literally have all the resources that you need. Use the wiki and search function next time.

Don't create multiple threads for basically the same issue
