need help with sha512

[Gelle]

Really, really tricky, I like that. 5000 rounds, this explains why it lasts so long to crack this hash and why rainbow-tables are a good alternative. But the salt is so long, that rainbowtables would need too much hdd-space. Seems to be much more safer than anything else I tryed till now and seems to be nearly invulnurable by brute-force, and uncrackable in general if you use the right password.
