The .GEM extension is a proprietary format used by ThunderSoft and GiliSoft to protect educational content and online courses.
To help find the exact tool or script you need, I can narrow down the options. Let me know: What is the of the file? Where did you obtain or download this file?

The .gem decryptor now sits in my utility belt, a Rust binary that serves as a monument to a week of frustration. It doesn't just decrypt files; it decrypts the thought process of a developer who is no longer there.
Several tools are available for decrypting gem files. Here are some popular ones: Where did you obtain or download this file
In rare legacy cases, Ventura Publisher or GEM Desktop used this extension for graphics, though these are never encrypted.

with open("decrypted.gem", "wb") as f: f.write(plaintext)
This is where the real work of a decryptor lies:
In this guide, we've covered the basics of Gem File Decryptors and provided an example implementation in Ruby. With this knowledge, you should be able to create your own Gem File Decryptor to work with encrypted gem files. Remember to always handle encryption keys securely and follow best practices for working with sensitive data.
I wrote the decryptor in Rust. I wanted the memory safety guarantees, but mostly, I wanted the speed. If I had to brute-force the date format, Python’s overhead would be too slow.
