Check out your installation directory, and go to :

AutoIt3\Examples\GUI\Advanced\encrypt.au3

That shows you how to encrypt and decrypt strings easily.

After that, check out the AutoIt help file. It allows you to check out the different functions you'll need, such as FileOpen, FileRead, and FileClose. Your program will have to open the txt or ini file, read it as a string, encrypt the string, write it to the original file, save the key somehow (or you won't get your original data back.) Then FileClose, and so on, and so forth.

As far as command line stuff goes, you'll have to research executing programs with parameters... you'll have to do something like

myScript.exe -f"fileToBeEncrypted.ini"

Not really sure on that one, but I think it's doable.
