pub fn polymod_run(values: &[u8]) -> u128Expand description
Run the BCH polymod over values starting from the BIP-93 initial residue.
Returns the final residue; callers XOR against the per-HRP target
constant (MS_REGULAR_CONST) to produce a checksum or to verify
one. Inputs are 5-bit symbols (u8 in 0..32); larger values are
reduced modulo 32 by the underlying step.
