* Extension(s) .pem, .crt, .cer<br />
* PEM encoded certificate is a file format for storing X.509 certificates. It is one of many PEM formats. <br />
* A PEM encoded certificate file is plain text. It contains one or more pairs of "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----" lines, with base64-encoded data between them. <br />
<br />
=== x509 PEM-formatted Commands ===<br />
# View the contents of an x509 PEM-formatted certificate.<br />
## <tt>'''# openssl x509 -noout -text -in <certificate-pem>.crt'''</tt><br />
# Convert from an x509 PEM-formatted certificate format to an x509 DER-formatted certificate.<br />
## <tt>'''# openssl x509 -in <certificate-x509-pem>.crt -outform der -out <certificate-x509-der>.crt'''</tt><br />
<br />
== x509 DER-formatted Information<br />
* Extension(s) .der, .crt, .cer<br />
* DER encoded certificate is a file format for storing an X.509 certificate.<br />
<br />
=== x509 DER-formatted Commands ===<br />
# View the contents of an x509 DER-formatted certificate.<br />
## <tt>'''# openssl x509 -noout -text -inform der -in <certificate-der>.crt'''</tt><br />
