To decrypt the output files, you must obtain the key pair. Decryption tools require this data formatted precisely as a hex string pair separated by a colon: KID:KEY .
These tools are intended for developers working with their own content or authorized, legal content archiving. Conclusion

N_m3u8DL-RE will output decrypted .mp4 video and .m4a audio files. Use FFmpeg to merge them into a single file without losing quality:
Describes a timed segment of the content (e.g., chapters or advertisement breaks). To decrypt the output files, you must obtain the key pair
Once you have the PSSH and the URL of the license server (also found in the Network tab, usually under requests containing keywords like widevine , license , or method=POST ), security researchers use CDM (Content Decryption Module) emulators or specialized scripts to fetch the keys.
What does this tell us?
If you need to watch your DASH stream offline, use the platform’s official offline mode (Netflix, Prime, Disney+ allow downloads in their apps). If you need to archive something you own, search for "Clear Key" encrypted MPDs (no license server required) or simply use a screen recorder on the official player—it is 100x easier than breaking Widevine.
Decrypting an MPD (Media Presentation Description) file typically refers to unlocking the video and audio streams it manifests, which are often protected by like Widevine. An MPD file is essentially a roadmap for MPEG-DASH streaming and does not contain the video data itself, only the instructions for the player to find and assemble encrypted fragments.

The license server rotates keys or uses different keys for different video resolutions (SD vs. HD).
