Yeah, reverse engineering would be the ticket.
This algorithm behaves similar to Pseudopassword by 90h on the PACE 5268ac. See link below what such an algo could look like in python.
Not mathematically possible to figure it out by comparing inputs to outputs.

(this uses the pseudopasswd utility as mentioned in /sbin/sysinit)
also, a python implementation of the pseudopasswd algo:

note that pseudopasswd unfortunately is essentially a hash func - it takes two chars on input to produce one char on
