You're more or less correct on table sizes, though. The len9 tables will be huge.

As such, if by "releasing" you mean "Ship me a 50TB storage array & I'll fill it for you," yes. If by "releasing" you mean "Generally available for download," probably not, as there's no practical way to share 50TB.


You actually have the storage for a 5 PB table?

The current target is NTLM 1-9 full US charset, plus extensions out to 12+ characters for smaller subsets (lower-numeric, etc).

The brute forcers are just a side project for cross-platform testing.

LE: http://en.wikipedia.org/wiki/Petabyte 50TB != 5 PB !
"A petabyte (derived from the SI prefix peta- ) is a unit of information or computer storage equal to one quadrillion bytes, or 1024 terabytes"

^ What he said.

50-100TB is not 5PB.

I don't have 5PB - yet. Only 5-6TB for now. Which will fill quickly once things are online, but we deal with that as it grows.
