Certificate & PEM Tools
Inspect PEM blocks, SSH fingerprints, X.509 markers, CSRs, and base64 certificate bodies.

Inspecting certificates and PEM blocks
TLS troubleshooting starts with PEM-encoded certificates, CSRs, and chains. Inspectors parse not-before and not-after dates, subject alternative names, signature algorithms, and key sizes. SSH fingerprint tools help verify host keys before first connect.
Expired intermediates cause chain errors that look like client misconfiguration. Weak signatures (SHA-1) still appear in legacy appliances. Confirm full chain order leaf to root when pasting into load balancer uploads.
Never paste private keys into untrusted online decoders. DevPipe runs inspection locally, but treat displayed material as sensitive and rotate if exposed during screen sharing.
Use PEM tools during certificate rotation windows to compare new CSR fields with issued certs before cutover. Redact serial numbers in public tickets if policy requires.
