Hello
i try to brutforce md5crypt i got
Integer overflow detected in keyspace of mask: ?1?1?1?1?1?1?1?1?1?1?1?1?1
my password have 13 in lenght and have only ?l?d
the password is only in hex
and i use this commande
hashcat.exe -O -m 500 md5.hash -a 3 ?1?1?1?1?1?1?1?1?1?1?1?1?1 --increment -1 ?l?d --increment-min 13 --force -w 4 --opencl-device-types 1,2 -w 4 --force
can help for this
Why not use ?h instead of ?1
Still 13 chars is going to take awhile even with multiple 3090s
The integer overflow is triggered because you've requested that hashcat generate more than 2^64 combinations, which is the limit (I believe).
You've asked for 26 letters, plus 10 digits, so 36 symbols, in 13 positions which is 36^13 (approx 1.70x10^20 combinations)
2^64 ~= 1.84x10^18
36^13 ~= 1.70x10^20
On a 3090, you'll get around 32621.8 kH/s for md5crypt you'll be a Very Long Time exhausting that keyspace
(1.70x10^20 keys / 32621800 key/sec) = 5,229,071,607,930 seconds (around 165,000 years).

If you can just use hex ?h, then you can get to 16^13, which means about 6 months on a 3090! Sorta doable, if you're desperate....
hi
thanks for reply
yes i have test with6 rtx 3090
with commande
hashcat.exe -O -m 500 md5.hash -a 3 ?h?h?h?h?h?h?h?h?h?h?h?h?h --increment -1 ?l?d --increment-min 13 --increment-max 13 --force -w 4
i have got estimate time is 280 days
