Including all-caps shouting and note about buggyness?

recommend raw_input("Choose: ") -- its safer and number not needed

>    if a == 1:
>      CryptFile()
>    elif a == 2:
>      DecryptFile()
>    elif a == 3:
>      readCypher()
>    elif a == 4:
>      readDecypher()
>    elif a == 5:
>      writeMess()
>    elif a == 6:
>      raw_input ("Hit Return to Exit...")

Switches can also be done with a dictionary:

_menu_func = { # outside function
  '1':CryptFile,
  '2': DecryptFile,
  '3': readCypher,
  '4': readDecypher,
  '5':writeMess,
  '6': (lambda :raw_input ("Hit Return to Exit..."))
}

and within function, just call
  _menu_func[a]()
