Is there a way to crack a 129 character length hash?

I was given a 129 character length hash ( probably whirlwind or SHA-512) to decrypt. I have tried cracking it using the whirlpooldeep and hashcat tools (without wordlists, i.e dictionary attack) but with no success. I'm sorry for the ambiguous question but this is all the information I have about my current task. Any suggestion would be gladly appreciated
