Keyspace questions
#1
Good afternoon,

Please excuse me as this is my first post.  I've read about keyspace, specifically from the FAQ page.  However, I wanted to know why there is such a discrepancy with keyspace values.  For example, -m 14000 outputs a keyspace of 34,359,738,368.  In reality, there are 72 quintillion possible combinations for the 8 character DES key.  

Taking something like hashtopolis into account, the entire keyspace gets taken by a single machine because the keyspace produced by hashcat itself is so low.  IE:  8x 3090's does about 450-500 Gh/s in -m 14000, so the hashtopolis assigns it to a single host.  Whereas the true keyspace would allow it to be distributed among several.

So my questions are these:

A)  It seems the "hashcat legacy" had a more accurate keyspace, why did that change?
B)  The hashcat output is 128^5, leaving the the remaining 3 bytes worth of keyspace out (DES is 8 bytes long).  Is that on purpose?  Is it because of the parity bits in DES?

Regards,

Raithe
