This python script is intended to automate the extraction of embedded certificates and keys from OpenVPN config files.

Unfortunately the GNOME Network-Manager is not able to automatically import OpenVPN config files with embedded certificates and keys. A workaround is to manually extract these and store them in separate files (e.g. see

// This was my attempt at K&R 1-22
// Though, this implementation has a bug wherein the last word of a short line is always printed on its own line. This is because
// there's currently no way for the program to know when the "split" word would fit on the current line.
// This solution is nice because it will work with arbitrarily long lines.
// The lines are read-in (80 chars or less at a time), the last space is sniffed out, then the last word is split,
// a newline is printed, and the "split" word is printed. On the next loop, the get_line function ends N chars from
// the line break, in order to acommodate the "split" word which has already been printed on the current line.

reverse :: [a] -> [a]
-- reverse can operate on _any_ list: Int, Float, Bool, MyCustomTypeClass.
-- The alternative would be writing a reverse variant for every type:
intListReverse :: [Int] -> [Int]
charListReverse :: [Char] -> [Char]
sort :: Ord => [a] -> [a]
-- sort can operate on _any_ list which is an instance of Ord: Int, Float, Bool, MyCustomTypeClass
