For demo purposes, any base64 string works. In production this would be an ML-DSA-65 public key (FIPS 204).

Why ML-DSA-65? — RSA and ECDSA can be broken by a sufficiently powerful quantum computer (Shor's algorithm). ML-DSA-65 (FIPS 204, formerly Dilithium3) is a NIST-standardized lattice-based signature scheme — quantum-resistant by design. All certificates issued here are signed with the CA's ML-DSA-65 private key.
