-> [!NOTE]
-> SLH-DSA is slow: see benchmarks below
+There are many different kinds,
+but basically `sha2` / `shake` indicate internal hash, `128` / `192` / `256` indicate security level, and `s` /`f` indicate trade-off (Small / Fast).
+SLH-DSA is slow: see [benchmarks](#speed) for key size & speed.
