Brute-force with only half of the cipher text

[al1984]

I am also looking for something similar, but I know the cipher text, but only 3 bytes out of 8 bytes of the plaintext.
Can something be implemented for this in the next version of hashcat? (To exhaust all of the keyspace of DES, and give you all of the possible keys that correspond to the match of the known cipher text with the partial known plain text)
