hashcat Forum

So ive been digging around to find a way to crack this handshake cap file i have. I know the pw is only uppercase letters and numbers, so i thought i'll try to make a wordlist like that with mask, but after a test run with a file that only contained 4 chars aircrack gave me the msg that the file i created is not in a supported format? O.o even tho it seems to be a regular txt so idk if thats normal or if i made a mistake somewhere along the way. I should point out that i do not have a CUDA compatibile graphic card so cant use hashcat at least thats what i think Either way thanks for any help in advance.

no idea how the title is connected to the content, but this forum is not about aircrack and hashcat only supports cracking WPA on GPU.
