Evidence must outlive the cryptography that sealed it: a post-quantum audit doctrine

Evidence outlives its cryptography when verification never depends on a single living scheme. Post-quantum signatures under FIPS 204 and 205 seal a hash-chained ledger, algorithm identifiers record what signed each entry, and a defined re-signing path renews trust without rewriting history.Originally published at https://mickai.co.uk/articles/evidence-must-outlive-the-cryptography-that-sealed-it.
