PEM / Certificate Decoder
Inspect PEM blocks and validate base64 locally
Paste a PEM certificate or key block, identify its envelope type, validate the base64 payload and see decoded byte counts without uploading anything.
PEM type: CERTIFICATE Base64 length: 247 Decoded bytes: 185 This browser-only decoder identifies the PEM envelope and validates the base64 payload. It does not call an online certificate parser.

A cosa serve
This tool checks the BEGIN and END envelope, strips PEM line wrapping, validates the base64 body and reports the decoded size. It is useful for quick sanity checks before pasting material into OpenSSL or a certificate manager.
Come si usa
- Paste a PEM certificate, public key or private key block.
- Review the detected type, encoded length and decoded byte count.
- Copy the summary for a support ticket or deployment note.
Privacy
Questo strumento funziona interamente nel tuo browser. Quello che inserisci non viene mai caricato, salvato o condiviso: chiudendo la scheda sparisce.
Domande frequenti
- Does this upload my certificate?
- No. The PEM text is parsed in your browser tab only.
- Does it fully parse X.509 fields?
- No. This version validates the PEM wrapper and base64 payload; it does not decode every ASN.1 certificate field.
- Can I paste private keys?
- The tool runs locally, but you should still avoid sharing private keys in screenshots or support messages.
