Built by a practitioner
Nitin Mekhiya

I build and secure systems where cryptography failures have real consequences -- payment APIs, banking integrations, certificate infrastructure. Post-quantum cryptography is not a topic I read about. It is something I need to understand because the systems I work on will still be running in 2035.
Daxipher is where I turn that work into tools other engineers can actually use. Every tool here exists because I needed it and could not find a good version of it anywhere.
NIST finalized ML-KEM, ML-DSA, and SLH-DSA in 2024. Banks, NBFCs, and fintech teams have a narrow window to migrate before harvest-now-decrypt-later attacks become a real threat. Most of them do not know where to start. That is what this is for.
Areas of expertise
What Daxipher is not
- xNot a blog or theory site
- xNot academic content
- xNot generic crypto tutorials
- ✓Practical tools for production systems
- ✓Visual explainers that teach by doing
- ✓BFSI-focused real-world use cases
Available for engagements
Work with me
If you're a bank, fintech, or engineering team dealing with cryptography challenges: TLS hardening, quantum readiness, PKI modernization: I can help. I work with production systems, not whiteboards.
Quantum Readiness Assessment
Full audit of your cryptographic inventory. Identify where RSA, ECC, and classical key exchange are used. Prioritized migration roadmap.
TLS / PKI Architecture Review
Review your TLS configuration, certificate chain, mTLS setup, and key management. Practical findings with clear remediation steps.
Crypto Architecture Consulting
Design or review the cryptographic architecture for a new system. Algorithm selection, key lifecycle, hybrid PQC strategy.
