Converting .p12 file to a pem

In some cases you want to convert p12 certificate files (PingFederate uses p12 files for example) to PEM files instead. This is easily done with openssl commands:

Certificate conversion:
$ openssl pkcs12 -in certificateandkey.p12 -out server.crt -clcerts -nokeys -passin pass:YourSecretPassword
MAC verified OK

Key conversion:
$ openssl pkcs12 -in certificateandkey.p12 -out server.key -nocerts -nodes -passin pass:YourSecretPassword
MAC verified OK

Done!
