AES-128 and Integer overflow detected in keyspace of mask
#1
Hi.

I'm trying to make myself familiar with hashcat.
I would like to get the right command arguments to crack 16 bytes crypt to 16 bytes plain using AES-128 (also 16 bytes).
All hex!

Code:
$ hashcat-7.1.2>hashcat -m 26401 hashes.txt -o cracked.txt -a 3 ?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h -w 4 ... OpenCL API (OpenCL 3.0 CUDA 13.0.84) - Platform #1 [NVIDIA Corporation] ======================================================================= * Device #01: NVIDIA GeForce RTX 2080 SUPER, 8191/8191 MB (2047 MB allocatable), 48MCU ./OpenCL/m26401_a3-optimized.cl: Pure kernel not found, falling back to optimized kernel Minimum password length supported by kernel: 0 Maximum password length supported by kernel: 16 Minimum salt length supported by kernel: 0 Maximum salt length supported by kernel: 51 Hashes: 2 digests; 2 unique digests, 1 unique salts Bitmaps: 16 bits, 65536 entries, 0x0000ffff mask, 262144 bytes, 5/13 rotates Optimizers applied: * Optimized-Kernel * Zero-Byte * Not-Iterated * Single-Salt * Brute-Force Watchdog: Temperature abort trigger set to 90c Host memory allocated for this attack: 1065 MB (51006 MB free) Integer overflow detected in keyspace of mask: ?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h Started: Thu Oct 09 17:25:39 2025 Stopped: Thu Oct 09 17:25:42 2025

When I use a mask of 15 bytes only, it works.
17 bytes is beyond hashcat design.
Can I do something to make this 16 bytes mask work?

Thanks
