Hello, I was wondering how to save a input inside of a file. This is my code so far.


os.loadAPI("tntapi")
tntapi.setScreen(1,4,colors.white,colors.black)
tntapi.easyText("Enter New Password",1,1,1)
password = io.read()

-- Save Password Here

Thanks,
Nolan

and more specifically fs.open http://computercraft.info/wiki/Fs.open

Open a file in write or append mode


local fileHandle = fs.open( "fileName", "w" )

then write to the file with the file handle you got. using 'write' or 'writeline'


fileHandle.writeLine( "Data" )

then close or flush to write the file


fileHandle.close( )

It will be more saftey to encrypt tbe password before saving.

It's be safer to hash the file than encrypt it. Take a look at this tutorial for FS though. Here.

Should help you with file systems.
