Answer : SSL file format , what is the filer server.crt and server.key

Here is the FAQ on openssl (ssl & certificate toolkit + library).

http://www.madboa.com/geek/openssl/
There:
http://www.madboa.com/geek/openssl/#cert-pkcs12

The pfx file is the pkcs12 certificate.

# export certificate and passphrase-less key
openssl pkcs12 -in mycert.pfx -out mycert.pem -nodes

# same as above, but youll be prompted for a passphrase for
# the private key
openssl pkcs12 -in mycert.pfx -out mycert.pem

Extract the cert & key with:
openssl rsa -in mycert.pem -out newcert.pem

The newcert .pem fiel should be splitable in an editor
as the key & crt are marked with lines like:

-----BEGIN CERTIFICATE-----                                                    
MII..................
blah blah blah
-----END CERTIFICATE-----
-----BEGIN RSA PRIVATE KEY-----
MII..............
blah blah blah
-----END RSA PRIVATE KEY-----
