Frequently Asked Questions

Q: Does this update affect the DASS167 commercial license? A: No. The licensing terms (perpetual or subscription) remain unchanged. However, nodes running v4.2.1 must phone-home for entitlement validation every 30 days (previously 90 days).

Q: My environment is air-gapped. Can I still use v4.2.1? A: Yes, but you must manually deploy the offline entitlement package (dass167-offline-license-2026Q2.bin). Without it, the service will enter read-only mode after 30 days. Thank you to our community for your continued

Q: Will the old dass167_exporter for Prometheus still work? A: No. The metrics port changed from 9123 to 9220, and several metric names have been renamed. Use the new dass167_exporter_v2 provided in the /contrib folder.

1. The “Keystone” Hashing Algorithm (Replaces SHA-224)

The previous hash mechanism, while secure, introduced unnecessary overhead when verifying packet integrity for payloads under 512 bytes. The new Keystone algorithm is a hybrid: dass167 updated

Speed: 2.3x faster for sub-1KB packets.
Collision resistance: Improved nonce derivation, addressing the edge case documented in CVE-2025-1447.
Backward compatibility: A translation layer automatically rehashes legacy tokens on first read.
