By itself, an MPD file is usually just plain text (XML). You don't typically "decrypt" the MPD file itself; you read it. However, the phrase "decrypt mpd" usually refers to one of two scenarios:
A. The Extraction of Keys (The "PSSH" Box)
Inside the MPD (or embedded in the video segments) is a box called the PSSH (Protection System Specific Header). This contains the key_id (which key is needed) and the system identifier (e.g., Widevine, PlayReady, FairPlay).
When a tool logs "decrypt mpd," it often means it has successfully parsed the manifest, identified the encryption scheme (usually Common Encryption or CENC), and is preparing to decrypt the actual media segments (the .m4s or .ts files) referenced inside the MPD. decrypt mpd file verified
B. The DRM Handshake To decrypt the content, the player must communicate with a License Server. The message implies that the client successfully: By itself, an MPD file is usually just plain text (XML)
Decrypting MPD files from commercial streaming services (Netflix, Amazon, Disney+, etc.) violates their terms of service and may breach copyright laws in many countries.

To understand the message, you first have to understand the container. MPD stands for Media Presentation Description. It is an XML-based manifest file used in MPEG-DASH (Dynamic Adaptive Streaming over HTTP).
When you stream video on Netflix, YouTube, or Amazon Prime, you aren't downloading a single .mp4 file. You are streaming small chunks of video. The MPD file is the "map" or "menu" that tells the video player:
You will need the pycryptodome library for the decryption logic.
