Quantum Readiness
Post-quantum migration matrix
Paste a cryptographic inventory and see what each algorithm becomes under NIST's post-quantum standards — with migration difficulty driven by where the key lives, not just which algorithm it is.
Mappings follow the NIST post-quantum standards finalised in 2024 — ML-KEM (FIPS 203), ML-DSA (FIPS 204) and SLH-DSA (FIPS 205). Difficulty is adjusted by the context words on each line, because where a key lives drives migration cost far more than which algorithm it is. This is a starting inventory, not an audit. Why the inventory is the hard part. Runs entirely in your browser.

These exist because the underlying problem is real. If the numbers you just put in look uncomfortable, that is usually worth a conversation.
