Module params 

SLH-DSA parameter set definitions and the Params trait. SLH-DSA parameter sets (FIPS 205, Section 11).

This module defines the Params trait and the twelve FIPS 205 parameter set structs — six SHAKE (§11.1) and six SHA-2 (§11.2). All parameter sets use Winternitz parameter w = 16 (lg_w = 4).

Each parameter set is identified by its hash family (SHAKE / SHA2), security level (128, 192, or 256 bits) and a size/speed trade-off suffix: “s” (small signatures) or “f” (fast signing/verification).
