Hi, I’m AJITOMI Daisuke (@dajiaji). I maintain mainly open-source cryptography libraries:

  • hpke-js — TypeScript HPKE (RFC 9180) atop the Web Cryptography API
  • PySETO — Python PASETO/PASERK (passes official test vectors; packaged by Alpine Linux)
  • python-cwt / pyhpke / crystals-kyber-js — COSE/CWT, HPKE, and ML-KEM/CRYSTALS-Kyber

Your sponsorship funds:

  1. Independent security audits (with a public summary)
  2. Vulnerability response & long-term maintenance (releases, CI, interop)
  3. Docs, examples, and conformance vectors
  4. Post-quantum transition work (hybrid KEM, migration paths)

Security and neutrality come first. No feature will trade off safety. Any amount of support directly improves quality and transparency.
