i can literally copy that into my own code in cgo comment blocks and use it that way... i will do this later, thanks for pointing me to it

also just maybe to mention, ECDH is an essential function for writing such as a custom noise protocol suite

i started poking at making one that uses the SIMD sha256 and x-only signatures a while back, removing the AES and not using chacha20 or whatever, a custom CTR style block cipher stream
