PEM certificates are frequently used for web servers as they can easily be translated into readable data using a simple text editor. PEM or Privacy Enhanced Mail is a Base64 encoded DER certificate. Openssl x509 -in certname.cer -outform PEM -out certname.pemДЄn X.509 certificate is a digital certificate based on the International Telecommunications Union (ITU) X.509 standard, which defines the format of public key infrastructure (PKI) certificates.

The easiest way in my opinion is to install Ubuntu on Windows 10 (I have an article coming on that soon, but it is very simple). Some have installed it on Windows but I do not trust some of the sources for it. OpenSSL is available on all Linux distros as well as macOS. Openssl pkcs12 -in certificate.pfx -out certificate.During the course of most security administratorвЂ™s life, you will inevitably need to convert certificates from certain formats to other formats.

Converting PKCS #12 / PFX to PKCS #7 (P7B) and private key.

Openssl pkcs12 -export -in certificate.cer -inkey privateKey.key -out certificate.pfx -certfile CACert.cer

Converting PKCS #7 (P7B) and private key to PKCS #12 / PFX.

Openssl pkcs12 -export -out certificate.pfx -inkey privateKey.key -in certificate.crt -certfile CACert.crt

Openssl pkcs7 -print_certs -in certificate.p7b -out certificate.cer

Remember, itвЂ™s important you keep your Private Key secured be sure to limit who and what has access to these keys. For Windows a Win32 OpenSSL installerВ is available.

Mac OS X also ships with OpenSSL pre-installed. GNU/Linux platforms are generally pre-installed with OpenSSL. вЂ‹While all of this can be a little confusing, thankfully OpenSSLВ can help you go from one format to another fairly easily. DERВ вЂ“ Distinguished Encoding Rules this is a binary format commonly used in X.509 certificates.pem files, though other file extensions such as. Base64В вЂ“ This is the standardized encoding for.These can be readily imported for use by many browsers and servers including OS X Keychain, IIS, Apache Tomcat, and more. It may also include intermediate and root certificates. pfx will hold a private key and its corresponding public key.

Applications often use different file formats which means that from time to time you may need to convert your certificates from one format to another.В To understand how to convert one certificate from one format to another itвЂ™s useful to understand how to identify the formats:

There are several different file formats that can be used to hold certificates and their private keys each with their own benefits. Converting Certificates From One Format to Another
