Hello,

im trying to crack a NetNTLMv1 hash but hashcat keep show me the error, Invalid hex character detected in mask charsets/DES_full.charset

# hashcat -m 14000 -a 3 -1 charsets/DES_full.charset --hex-charset 14000.hash ?1?1?1?1?1?1?1?1

Hello,

i fix it.

hashcat -m 14000 -a 3 inputs.txt --hex-charset -1 /usr/share/hashcat/charsets/DES_full.hcchr ?1?1?1?1?1?1?1?1 # for NetNTLMv1(-ESS/SSP) to DES-keys (KPA-attack) of user/computer account with 100% success rate, then regenerate NT-hash with these DES-keys on https://shuck.sh/converter.php.

there is other methodes to crack NetNTLMV1

john --format=netntlm hash.txt

hashcat -m 5500 -a 3 hash.txt # for NetNTLMv1(-ESS/SSP) to plaintext (for user account)

hashcat -m 27000 -a 0 hash.txt nthash-wordlist.txt # for NetNTLMv1(-ESS/SSP) to NT-hash (for user and computer account, depending on nthash-wordlist quality)


RE: Invalid hex character detected in mask charsets/DES_full.charset - MiMaz7707 - 09-14-2025

i had to use the full path of DES_full.hcchr (/usr/share/hashcat/charsets/DES_full.hcchr) instead of charsets/DES_full.hcchr
