Testing DES 14000 mode has issues and I'm seeking help.
#1
I found an issue during testing in mode 14000. Using the fixed plaintext "0000000000000000" and fixed key "111111112B3F4D5F", the ciphertext "5944ECB3C8BDD326" was generated.

Using the command "hashcat -a 3 -m 14000 5944ECB3C8BDD326:0000000000000000 -1 charsets/DES_full.hcchr --hex-charset ?1?1?1?12B3F4D5F" can find the ciphertext.

However, I want to specify the first two digits of the ciphertext as numbers. I tried the following commands, but they did not work:

"hashcat -a 3 -m 14000 5944ECB3C8BDD326:0000000000000000 -1 charsets/DES_full.hcchr --hex-charset ?d?1?1?12B3F4D5F"
"hashcat -a 3 -m 14000 5944ECB3C8BDD326:0000000000000000 -1 charsets/DES_full.hcchr -2 charsets/DES_special/DES_numeral.hcchr --hex-charset ?d?1?1?12B3F4D5F"
How can I set the command to fix the first two digits as numbers?

There are no digits in 111111112B3F4D5F (which is a hexadecimal representation of a binary string).
