TentHash Rust

Rust implementation of TentHash. TentHash is a high-quality, non-cryptographic, 160-bit hash function. It is also portable, easy to implement, and reasonably fast.

TentHash's target applications are data fingerprinting, content-addressable systems, and other use cases that don't tolerate hash collisions.

Importantly, TentHash is explicitly not intended to stand up to attacks, and should never be used where the hash function itself has security considerations. Its robustness against collisions is only meaningful under non-adversarial conditions. In other words, like a good tent, it will protect you from the elements, but will do very little to protect you from attackers.
