Hi,
Encryption is hardly the word... it just changes the file extensions based on the date. VB code on the other hand is encrypted (compressed) by AM via something similar to Huffman based on the project name.
What you need is a tool to alter the hex values of you file (encrypt), the reverse will happen when playing your game via an OCX... the decrypted file must then be stored in the memory (or a temp location) and used by AM and removed again.
Of course this comes with a price... slowness...
You could also only change the file header... faster.
I'm afraid you will have to write some code to create a plugin. Perhaps some ready to use tools can be used like

In IMHO this is not worth the effort as most people will have no use for game parts... I always checkout the BINK movie files in a game first, but thats it
Good luck...
With best regards,
