Hi @china4sq and thanks for your interest in the project.
May I have simpler parameters, such as 20 bits, not 80 bits in K-163?
Unfortunately that is not possible. The parameters of K-163 are not variable.
I benchmarked K-163 on an STM32 ARM Cortex-M3 some years ago. As far as I remember, it takes some 100 milliseconds.
What kind of hardware are you on?
such as 20 bits
I don't want to judge, but 20 bits of encryption is really not much!! From https://en.wikipedia.org/wiki/40-bit_encryption
A typical home computer in 2004 could brute-force a 40-bit key in a little under two weeks, testing a million keys per second
So commodity hardware from 2004 could enumerate all possible 20-bit keys in a second. You would be very vulnerable to offline-attacks if they are possible.
I know there is some hand-waving here, because of the conversion to symmetrical-equivalent entropy, but I think the point still stands.
I am closing this issue, since I've answered your first question. If you have further comments/questions, feel free to keep posting.
