Thank you for the correction. Reckon thats going to make searching for
info a might easier.

For some reason I have it with a 'k' in my notes.

Anyhow, thats again.

As Wikipedia says ( https://en.wikipedia.org/wiki/Streebog ),
Streebog uses Merkle-Damgård construction and mathematically is more
closed to SHA1/SHA2 and similar hash functions. It can be called rather
"classic" construction, but much more effective and simple that previous
GOST R 34.11-94 hash function standard.

So many things related to those classic SHA1/2-like functions are
appliable to GOST R 34.11-2012 too.

By the way, it should be called "Streebog"", "Stribog".

SHA-3 and GOST-R/Stribok

[xorcist]

Anyone know of some good reference material comparing and contrasting
these hash functions?

>From what I know of the mathematics, they are quite unrelated, and it
should be very difficult to make inferences about inputs by looking at
their comparative outputs, but I'd love to see some work in this regard,
if there is any out there.

I have an application where it would be best to use two hash functions,
but I'd like to make sure there is some "orthogonality" there.
