How this tool works
SSL/TLS tools parse certificate, CSR, key, or live handshake data with OpenSSL-compatible logic. They surface subject, issuer, SAN, validity, chain, format, and key-matching details so deployment issues are easier to isolate.

When should I use PEM Bundle Splitter?
Splits a PEM bundle, identifies leaf/intermediate/root certificates, and rebuilds an ordered fullchain. Use it when you need a quick, readable result before cross-checking with production data or related tools in the SSL / TLS group.
Should I verify the result before applying changes?
Yes. Treat the output as an operational aid: review the source input, compare it with authoritative systems, and test changes in the correct environment before rollout.
