beatsDefault URLSession TLS Validation vs. Custom Delegate for Self‑Signed Certificates
Goal: Allow an iOS/macOS app to connect to a backend that uses a self‑signed TLS certificate while ensuring that hostname verification remains intact and the connection is not vulnerable to man‑in‑the‑middle attacks. Constraint: URLSession’s built‑in validation rejects self‑signed certificates unless the app provides a delegate that evaluates the server’s Se
swiftDoes Harbor support per-endpoint certificate trust for webhook notifications?
When Harbor must deliver webhook notifications to an HTTPS endpoint signed by a private CA, the goal is to keep certificate validation enabled without trusting that CA across every outbound connection. The uncertainty is that Harbor's core and jobservice containers use their own operating system trust store, so a private CA installed on the production host i

Why does DBeaver fail to validate a PostgreSQL server's SSL certificate when the hostname resolves via DNS, and how can I configure a custom truststore to fix it?
When connecting to a PostgreSQL instance over TLS using DBeaver, the client sometimes rejects the server's certificate despite the certificate being valid and trusted by the system Java keystore. The issue appears to be related to DNS resolution of the host name used in the connection string, which may cause a mismatch between the certificate's subject alter
