PKCS#12 archives (commonly known as .pfx files) usually contain both a certificate and its private key, sometimes with password protection. In order to use these with a server like nginx or Apache, we need to extract these objects and convert them using openssl.

wget ftp://yourwebsite.com/some/directory -nv -r -N -l inf -nH --ftp-user='username' --ftp-password='password'
