how long it takes

Hi guys,

64 character hexadecimal hashed with sha512
128 character hexadecimal hashed with sha512
I found out that some of the apps are using 128 character version of this while some of them using 64 character version for seed generation.

I wonder if 64 character hexadecimal could be cracked with very very powerful vps setup?

Really appreciate answers,

Thanks!
