so in your example:
sha256('ffffffffffffffff0000000000000000') = 9d16bfa811f70a01d13ecbe0bb081c80f89e37b72383566740ef849617e80ab2
sha256('FFFFFFFFFFFFFFFF0000000000000000') = 5219f4e314c19218f9eb9393c077c8858caff6b546e142c8cfc4c936bec769d6
upper / lower case letters possible in such strings? or do we talk about a hex representation of the found password?
even when just appending the 8 times 00 per rule, the first half, 8 times 00 to ff or FF or mixed (as string) is quite a huge keyspace, it is 16^16 and should be result in an overflow by hashcat
it's just lowercase letters/chars 0123456789abcdef, first 8 bytes of output "array", as in example,
last 8 bytes of array is always 00 00 00 00 00 00 00 00
mask that i put in example, goes pretty quick on hashcat, but results in "exhausted" ...
i'm gonna find some known hash/result and put it in ...
just on thing i'm not sure - is my mask good ?
-a 3 -1 0123456789abcdef -2 0 ?1?1?1?1?1?1?1?1?2?2?2?2?2?2?2?2
or
-a 3 -1 0 ?h?h?h?h?h?h?h?h?1?1?1?1?1?1?1?1
should be basically the same, as "h" = 01234567890abcdef
