how does DES hash work? - hokus - 06-15-2021
I know DES as an encryption method: plaintext + key -> ciphertext.
But in hashcat DES is used as a hashfunction and the password "hashcat1" results in hash a28bc61d44bb815c:1172075784504605
So, I can't find anything about a DES hash function which results in a hash with the above form (xxx..:xxx..). Where can I find information on what is used here?

Is just that the 56 bit keyspace of DES is feasible to brute force with a few GPU in a short time, so you can brute force they key with a given pair of CryptText and PlainText.

Aaaahh, the "hash" is ciphertext:plaintext! Thanks, that was what I missed!
