Explanation

Rob, I know you are a very busy man, but the other guys reading this article could have looked it up. I didn't know anything about all this terms before reading this article, but I has taken me less than a minute to find the answer and I am not a native English speaker. Internet is great... if you use it. So, come on guys, fire up those browsers and make those search engines crunch some databases.

Ok, here is an straightforward explanation for PEM, DER and other formats:

Certificate And Key Formats
----------------------------------

PEM - Can contain all of private keys (RSA and DSA), public keys (RSA and DSA) and (x509) certificates. It is the default format for OpenSSL. It stores data Base64 encoded DER format, surrounded by ascii headers, so is suitable for text mode transfers between systems.

DER - Can contain all of private keys, public keys and certificates. It stored according to the ASN1 DER format. It is headerless - PEM is text header wrapped DER. It is the default format for most browsers.

PKCS#12 - Also known as PFX files. Can contain all of private keys, public keys and certificates. It stores in a binary format. See <http://www.drh-consultancy.demon.co.uk/pkcs12faq.html> for more information on the format, and its support in OpenSSL

I hope this helps.

Hopefully this evening I will post a step-by-step guide of importing a self-made certificate. Right now it does not seem to work with my own, but I am working on it.

Hang on!

Alex
