• Cryptographic Bill of Materials (CBOM): Step 1 of PQC Migration

  You can't migrate cryptography you can't see. A practical guide to building a Cryptographic Bill of Materials — what to inventory, how to find hidden crypto, how to score by data lifetime, and how the CBOM becomes your post-quantum migration plan.

• Post-Quantum Cryptography Deadlines: What 2027, 2030 & 2035 Mean for Your Stack

  NSA's CNSA 2.0 sets a 2027 acquisition deadline; NIST deprecates RSA-2048 and ECC P-256 by 2030 and disallows them by 2035. A plain-English guide to the PQC timeline and what each date actually requires you to do.

• Hybrid Cryptography: Why Ed25519 + ML-DSA Is the Safe Migration Path

  Why serious post-quantum rollouts combine a classical and a post-quantum algorithm instead of switching outright. How hybrid signatures and KEMs work, how to combine them correctly, the pitfalls, and why QAuth signs with both Ed25519 and ML-DSA-65.
