Once we have all the helpers (#175) and keys (#176) defined, we can get to actual signing and verification

  • Define signature type - Section 4.1.8
  • Implement buildAuth function for computing authentication path, and add references / notes about how inefficient it is and why you should use an alternate approach - Section 4.1.9
  • Implement treeSig algorithm - Section 4.1.9
  • Implement XMSS_sign algorithm - Section 4.1.9
  • Implement XMSS_rootFromSig algorithm (with warnings about use) - Section 4.1.10
  • Implement XMSS_verify algorithm - Section 4.1.10
