+Note, there seems to be a lot of confusion around the file extensions given
+to these keys. For example, a .pem file can contain all the following:
+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. A .pem file may contain any number of keys either public or
+private. We use it in cases where there is both a public and a private
+key.
+
+Typically, above we have used the .cert extension to refer to X509
+certificate encoding that contains only a single public key.
