here is an example using it to crack NDS and to get the K1_unique after getting the ecw/dcw pair (replace them in the command below) :
Note: This command would be applied to some server with number of high performance GPUs on it something like RTX2080 , RTX 3090 etc. so rent one from the internet .
hashcat -m 14000 ECW:DCW -o cracked.txt -a 3 -1 /usr/share/hashcat/charsets/DES_full.charset --hex-charset ?1?1?1?1?1?1?1?1 -w 4 –force
other examples :
hashcat -m 14000 d931f92e0475753e:aabbccddee112233 -o cracked.txt -a 3 -1 /usr/share/hashcat/charsets/DES_full.charset --hex-charset ?1?1?1?1?1?1?1?1 -w 4 --outfile-format 5 --force
hashcat -m 14000 -a 3 0000000000000000:8ca64de9c1b123a7 -o cracked.txt --potfile-disable --markov-disable -1 /usr/share/hashcat/charsets/DES_full.charset --hex-charset ?1?1?1?1?1?1?1?1 -w 4 --force
Good luck and Regards
