SPHINCS is a post-quantum secure hash-based digital signature scheme.
This implementation is based on the original SPHINCS implementation available in Supercop, but uses an optimized SHA256 implementation.
On Intel Skylake this implementation achieves the following performance:
| Operation | Cycles |
|---|---|
| KeyGeneration | 8.823.584 |
| Signing | 144.530.760 |
| Verify | 3.301.330 |
