I am trying to get SUM(see signature) to write the grub password in encrypted form to menu.lst. Currently it writes the password in plain-text and that is not too clever...
This is the function I currently use:
def on_update_password_button_clicked(self, widget):
if self.password_entry.get_text() == self.confirm_password_entry.get_text():
password=self.password_entry.get_text()
if self.password_protect_check.get_active():
change_config("password", None, "password "+password+"\n")
else:
change_config("password", None, "#password "+password+"\n")
self.password_notify_label_mismatch.hide()
self.password_notify_label_updated.show()
else:
self.password_notify_label_updated.hide()
self.password_notify_label_mismatch.show()
And here is the "change_config" function:
def change_config(identifier, old_value, new_value):
"""Changes the configuration file based on the passed values."""
line_number=get_line_number(identifier)
lines=get_lines_of_file(Config.menu)
line=lines[line_number]
if old_value == None:
lines[line_number]=new_value
elif old_value == "vga=":
place=line.find(old_value)
if place != -1:
line=line[:place]+new_value+line[place+7:]
else:
place=line.find("\n")
line=line[:-1]+" "+new_value+"\n"
lines[line_number]=line
else:
if old_value[0] != "#" and line.find(" "+old_value) != -1:
old_value=" "+old_value
if old_value[0] == "#" and line.find("# "+old_value[1:]) != -1:
old_value="# "+old_value[1:]
line=line.replace(old_value, new_value)
lines[line_number]=line
output_file=open(Config.menu, 'w')
for out_line in lines:
output_file.write(out_line)
output_file.close()
What would be the best way to send an encrypted password to the file instead?
I tried the python md5 module, but the encrypted password corrupts the file if passed through the change_config function(or if it is written directly)
I also thought about using the grub-md5-crypt program and pipe the output through sed or something, but I have no idea how to send the user-submitted password to grub-md5-crypt.
Any help is appreciated.
