// File extensions for cryptographic certificates aren't really as standardized as you'd expect.
// Windows by default treats double - clicking a.crt file as a request to import the certificate
// So, they're different in that sense, at least, that Windows has some inherent different meaning
// for what happens when you double click each type of file.
// One is a "binary" X.509 encoding, and the other is a "text" base64 encoding that usually starts with "-----BEGIN CERTIFICATE-----".
// into the Windows Root Certificate store, but treats a.cer file as a request just to view the certificate.
// CER is an X.509 certificate in binary form, DER encoded
// CRT is a binary X.509 certificate, encapsulated in text (base-64) encoding
// Most systems accept both formats, but if you need to you can convert one to the other via openssl
// Certificate file should be PEM-encoded X.509 Certificate file:
// openssl x509 -inform DER -in certificate.cer -out certificate.pem
