What is a .pem file?

application/x-pem-file

PEM (Privacy-Enhanced Mail) is a text container that Base64-encodes DER binary data between BEGIN/END header lines, used to hold X.509 certificates, certificate requests, and keys. A single .pem file may contain a certificate, a chain, or a private key, which makes it the most common format for TLS material.

How to use a .pem file

Use an example .pem certificate to test X.509 and TLS parsers, PEM decoders, certificate-chain validators, and PEM-to-DER converters. This is published sample material — never a real production key.
