""" This function takes an existing unencrypted password, and returns an
encrypted version so that current test programs can update the 
dbConnectionDefs.py files, or anywhere else where a password was originally
stored unencrypted.

Let's assume that you have run the wizard, and have a directory with your 
generated app. One of the file is named 'dbConnectionDefs.py'; in it will be 
a line that reads:

		"password": "mypassword",
		
with the appropriate password on the right. To convert this file to the 
new encrypted style, you need to run this utility as follows:

	python pwEncrypt.py mypassword
	
This will print out an encrypted version of 'mypassword'; copy that, and 
paste it into your dbConnectionDefs.py file so that the password line reads:

		"password": "M96MD1BC5UE8TE1P77C99T68UE0VDB",
		
In other words, make sure that the password stored in the file is the one 
returned by this utility when you pass it the original, unencrypted
password.
