PEM encoded certificate

PEM encoded certificate is a file format for storing X.509 certificates. It is one of many PEM formats.

Format
A PEM encoded certificate is simply a base64-encoded DER encoded certificate file, with some delimiting lines added.

More than one certificate may be stored in a single file. There may also be other types of objects, such as private keys, stored in the same file.

Identification
A PEM encoded certificate file is plain text. It contains one or more pairs of " " and " " lines, with base64-encoded data between them.

Examples
To display the contents of a PEM encoded certificate using OpenSSL: openssl x509 -noout -text -in example.crt

To convert from PEM encoded certificate format to DER encoded certificate format: openssl x509 -in example.crt -outform der -out example.der
