macjbc/PetoronHash-System

PetoronHash-System is a zero-adoption, zero-velocity personal cryptography project with no community engagement or external validation. The README makes post-quantum resistance claims but provides no peer review, formal security analysis, or cryptographic validation—red flags in this domain. The combination of variable-output hashing and domain separation are well-established cryptographic patterns (cf. BLAKE3, XOF construction from SHA-3). The 'dependency-free C++20' angle is implementation convenience, not novelty. At 216 days old with no stars, forks, or evidence of use, this is a personal experiment/portfolio project. Frontier labs (OpenAI, Anthropic, Google) have zero incentive to compete; they license vetted cryptographic primitives (libsodium, BoringSSL, etc.) with formal security guarantees. The risk of obsolescence is not from frontier labs but from the cryptographic community's well-justified skepticism of unvalidated hash functions. Defensibility is minimal: no moat, no adoption, no ecosystem, trivially reproducible by anyone comfortable with C++20 and cryptography. If the author seeks serious adoption, this would require: (1) formal security proofs, (2) NIST/peer review, (3) third-party cryptanalysis, and (4) comparison against established post-quantum candidates (CRYSTALS-Dilithium, etc.). Currently it is a learning project, not a production or even beta-stage tool.
