Sıkça sorulan sorular

Quick answers.

›What certificate formats are supported?

The tool supports PEM format, which typically starts with `-----BEGIN CERTIFICATE-----`, as well as binary DER files. It can also parse Certificate Signing Requests (CSRs).

›Is my certificate data secure?

Yes. The decoding process is performed entirely within your web browser. No certificate data or metadata is ever uploaded to our infrastructure.

›What information can I see in the output?

You can view the Common Name (CN), expiry dates, serial number, public key algorithm, and fingerprints (SHA-1 and SHA-256). It also highlights if a certificate is currently expired.

›Can it decode a chain of certificates?

If you paste a bundle containing multiple certificates, the tool will decode and display the details for each individual certificate in the order they appear.
