About Certificate Decoder Pem
Certificate Decoder Pem is used to decode and inspect a PEM-formatted SSL/TLS certificate, CSR, or public key. It parses the Base64-encoded PEM block and displays the decoded fields including subject, issuer, validity, and public key info. PEM files starting with "BEGIN CERTIFICATE" are certificates; "BEGIN CERTIFICATE REQUEST" is a CSR — paste the correct type for accurate results. Certificate Decoder Pem runs entirely in your browser at abovetool.com — keys, passwords, and file contents never leave your device.
