Tip of the daybest practice
When exporting PFX, prefer least-privilege: only include the chain you need, and avoid reusing passwords across environments.
For CSR issues, validate `CN`, SANs, and org fields early—most issuance delays are metadata mismatches.
When adding new tools, keep them “offline” by default (no external calls) unless you really need network lookups.
