Findings
INFO
Hybrid key establishment negotiated (X25519MLKEM768)
6addaf97
The handshake on api.firstnationalbank.com:443 settled on X25519MLKEM768, which carries an ML-KEM-768 share alongside the classical X25519 share. A transcript recorded today stays closed even against a cryptographically relevant quantum computer.
Remediation. No action required. Keep the hybrid group first in the preference list and monitor for silent downgrade.
