Which MACs can be converted into a secure unkeyed hash function?

As pointed out by others, MAC systems based on hash functions can trivially be made back into hash functions by making the key a public constant. E.g. $hash(msg) = HMAC(key_{const}, msg)$. It's also ...

Looking for a lightweight hashing algorithm

A simple ARX construct can do with less than the required 400 bytes of executable code, if we require neither: speed, low RAM usage, having withstood the test of years of cryptanalysis attempts after ...

Ascon, (Reference Implementation) Also, a bare-minimum of 700-octet Kolmogorov complexity seems to be necessary for the application(s) of secure hashing.
