SPHINCS+ Stateless Hash-Based Signature Validator
Validates SPHINCS+ stateless post-quantum hash-based digital signature parameters and verification tokens.
Notice: engineering verification utility. Use test or de-identified data and verify results independently before relying on them.
How it works
Standard: NIST FIPS 205 / SPHINCS+ Stateless Hash-Based Signature Standard
Formula: Verify SPHINCS+ parameter set (e.g. SPHINCS+-SHA2-128f) and signature hash digest
Checks: Parameter set acronym and signature string
