BLAKE2 on 32-bit words, for the microcontrollers and 32-bit targets where BLAKE2b's 64-bit arithmetic hurts. On a desktop CPU BLAKE2b is usually the faster one.

ts
create("blake2s").hash("abc").digest;
// "508c5e8c327c14e2e1a72ba34eeb452f37458b209ed63a294d999b4c86675982"

WireGuard picked this one. HMAC works here too, over BLAKE2s's 64-byte blocks.
