LUKS V2 Support

[mintcocs]

Hi, im trying to test how can i decrypt my encrypted disk with LUKS use hashcat. 

run with this command: hashcat -m 34100 -a 0 luks.hash rockyou.txt

But got :

Code:

hashcat (v7.1.2) starting METAL API (Metal 370.64.2) ========================== * Device #01: Apple M1, skipped OpenCL API (OpenCL 1.2 (Nov  8 2025 19:10:43)) - Platform #1 [Apple] ==================================================================== * Device #02: Apple M1, GPU, 2730/5461 MB (512 MB allocatable), 8MCU Minimum password length supported by kernel: 0 Maximum password length supported by kernel: 256 Minimum salt length supported by kernel: 0 Maximum salt length supported by kernel: 256 Hashes: 1 digests; 1 unique digests, 1 unique salts Bitmaps: 16 bits, 65536 entries, 0x0000ffff mask, 262144 bytes, 5/13 rotates Rules: 1 Optimizers applied: * Zero-Byte * Single-Hash * Single-Salt * Slow-Hash-DimensionY-LOOP Watchdog: Temperature abort trigger set to 100c * Device #2: This system does not offer any reliable method to query actual free memory.

Is there any ways to solve that issue?

I read your error as a memory issue on the mac you're running hashcat from. LUKS2 uses argon which is a very memory heavy algorithm, so best solution is probably to try some other hardware, or play around with other algorithms.
