3DES (hc 3.40): K1 == K3 and K1 != K2 possible?

[al1984]

I have edited the 3 m14100 files in order to try and get k1=k3 and k1 independent of k2, and compiled hashcat. Now I get integer overflow.
Any help on how to set k1=k3 and k1 independent of k2 properly would be appreciated.
Sorry if this is the wrong thread to post in.
Thanks.
