Just a guess: With a key 0xAAAAAAAAAAAAAAAA you do not have to care about Little endian/Big endian, because the key has always the same byte value. Try again with 0xBBBBBBBBBBBBBBBB and update your C...

Post: RE: rule to skip passwords with repeats

That's not what rules do. What you're looking for is maskprocessors -q option. Please use maskprocessor in combination with hashcat's stdin feature.

There's both swap32() and swap64() as well as swap32_S() and swap64_S() for scalar datatypes.

Post: RE: No keyspace for the distributed hashcat v3.00

Please use --keyspace. You will find out that the use of --keyspace is not allowed in combination with -i, which is required to tell hashcat to increase the mask-length with each iteration by one. So ...

Post: RE: Nvidia fan use issues

If you set it even lower, for example "--gpu-temp-retain 10", then it should instantly set the fan speed to 100%. Please try that and what philsmd said.

Bitsliced DES makes sense with brute-force -a 3 mode. Otherwise the register pressure is too strong and your data gets swapped on global memory, making everything slower than it would be without bitsl...

Yes, hashcat fully supports them. But they are very unstable and therefore they often crash. To verify it's not hashcat, compile hashcat from sources with DEBUG=1 make and then run the same command...

Yes, that's true. You have either switch to windows, buy a new gpu with amdgpu-pro support or stick to an older distribution. Thanks AMD :)
