Certificate Chain Validator

v1.2.1

Inspect certificate chains and validate ordering, expiry, and trust assumptions.

Inspects PEM certificate chains — validates ordering (leaf → intermediate → root), checks expiry dates of each certificate, and flags common chain configuration mistakes.

How to use
  • →Paste a PEM certificate chain (multiple -----BEGIN CERTIFICATE----- blocks) into the input.
  • →The tool checks order, expiry, and whether each cert is signed by the next in the chain.
  • →Use this when debugging "incomplete chain" TLS errors or before deploying a certificate.
