So I'm having an issue with HashCat not being able to crack a hash. I have written a python program that cracks it just fine but I don't think I am entering the mask right for hashcat. I've tried ?b and ?h since the key that the python program brings back is a hex string bf851a

hashcat -m 1410 -a 3 c88cedb68bf463557d9fee922b43fb3e6de00472b98c12e492d24f0774512f72:595d5727ecd598bc ?b?b?b

Here is the Python code for reference:

def 
sha256(ascii_input: str) -> str:
    byte_input = ascii_input.encode('latin-1')  
# Using 'latin-1' to match previous behavior
    return 
hashlib.sha256(byte_input).hexdigest()
def 
int_to_uint8_array(num: int, length: int) -> bytes:
    
return 
num.to_bytes(length, byteorder='big')
def 
find_key(hash_input: str, min_bits: int, max_bits: int) -> Optional[str]:
    salt = bytes([89, 93, 87, 39, 236, 213, 152, 188])
    salt_hex = salt.hex()
    print("Salt:", list(salt))
    print("Hex Salt:", salt_hex)
    
for 
y 
in 
range(min_bits, max_bits):
        min_key = 2 ** y
        max_key = 2 ** (y + 1)
        
for 
i 
in 
range(min_key, max_key):
            byte_length = math.ceil((y + 1) / 8)
            key_bytes = int_to_uint8_array(i, byte_length)
            key_hex = key_bytes.hex()
            
# Concatenate key bytes with salt
            
salted_key = key_bytes + salt
            
# Convert to ASCII string using 'latin-1'
            
ascii_str = salted_key.decode('latin-1')
            
# Compute SHA-256 hash using hashlib
            
current_hash = sha256(ascii_str)
            
if 
current_hash == hash_input:
                print(f"Key found: {key_hex}")
                return key_hex
            if i % 1000000 == 0:
                print(f"Checked key: {key_hex}")
    print('Search complete. Key not found.')
    
return None

Any help on this would be greatly appreciated.
