Q

List and detail the certificate formats.

A

PEM, DER, PFX, CER, P12, P7B

PEM - most common format for CAs, contains any or all of the whole cert chain and keys, widely used by Unix, base 64 encoded ascii files, extensions such as .pem, .crt, .cer, .key, apache uses PEM

DER - binary form of a PEM key, storage of a single cert without private key or the chain, .cer and .der, typically used by Java

PFX, PKCS12, P12 - interchangeable, for storing a server or intermediate cert along with private key in one encrypted file

P7B / PKCS7 - contains certificates and chains, but not the private key, has extension .p7b, .p7c, used by several platforms.
