Securing RDP Connections with Trusted SSL/TLS Certificates
This article covers how to secure RDP Connections with Trusted SSL/TLS Certificates.
To Check What Certificate RDP Is Using
You can check the thumbprint of the certificate the server is using. Windows Key+R > Regedit {Enter} > Navigate to:
HKEY_LOCAL_MACHINE
> SYSTEM > CurrentControlSet > Control > Terminal Server > WinStations > TemplateCertificate
You can check this with the actual Certificate> Windows Key+R > mmc {enter} > File > Add/Remove Snap-in > Certificates > Local Computer > Open Certificates > Personal > Certificates > Locate the certificate you ‘Think’ RDP is using and you can compare its thumbprint with the registry key.

Easy way to convert cPanel SSL Certificate from PEM format to PFX
pem is a de-facto file format called Privacy-Enhanced Mail. These are interchangeable file extensions for the PKCS#12 format.
Technically, PKCS#12 is the successor to Microsoft's PFX format, but they have become interchangeable. PKCS#12 files are archives for cryptographic material.
PKCS#12 (also known as PKCS12 or PFX) is a binary format for storing a certificate chain and private key in a single, encryptable file.
All SSL Certificates require a private key to work. The private key is a separate file that's used in the encryption/decryption of data sent between your server and the connecting clients.
A private key is created by you—the certificate owner—when you request your certificate with a Certificate Signing Request (CSR).
Basically, the default SSL file format used by apache web server is the PEM format. Whereas PFX files are used on MacOS and Windows systems to do export and import activities of private keys and certificates.
