SSL Certificate Decoder
Paste your PEM-encoded SSL/TLS certificate to decode all its fields — subject, issuer, expiry, key info, SANs, and fingerprints.
Paste your SSL certificate above and click Decode Certificate to inspect all its fields.
How to get your certificate in PEM format
Your SSL certificate in PEM format is a text file that begins with -----BEGIN
CERTIFICATE----- and ends with -----END CERTIFICATE-----. It is provided
by your Certificate Authority after they sign your CSR.
You can also extract it from your server: on Apache, it's the file referenced by
SSLCertificateFile; on Nginx, it's the first block in your
ssl_certificate bundle file.
