//This script will password protect your Maya file.
//It accomplishes this by creating a scriptNode that
//prompts you for a password as soon as the file is 
//opened. The file doesn't fully open until you have 
//entered the proper password. If you don't know the 
//password, too bad.

//The major weakness here is that the password is 
//stored as normal plain text in a script node. This 
//means that the password may be read and edited if 
//you save your file as an .ma (Maya ASCII) file.

//To run this script source it in Maya and type 
//"jpProtect" in the script editor or command line.
