keyutils bindings for Python

Project description

python-keyutils is a set of python bindings for keyutils (available from http://people.redhat.com/~dhowells/keyutils), a key management suite that leverages the infrastructure provided by the Linux kernel for safely storing and retrieving sensitive infromation in your programs.

Usage

The C extension module follows closely the C API (see add_key(2), request_key(2), keyctl_read_alloc(2)).

Exceptions also follow the C API. The only notable difference is for request_key: when the key is not present, None is returned, instead of raising an exception (which is usually a more expensive operation).

Note that the function parameters are passed as bytes not strings! On python 3 this usually requires an explicit param.encode() call.

For example:

import keyutils

# NOTE: only pass `bytes` to the keyutils API:
name = b'foo'
value = b'bar'
ring = keyutils.KEY_SPEC_PROCESS_KEYRING

key_id = keyutils.add_key(name, value, ring)

assert keyutils.request_key(name, ring) == key_id
assert keyutils.read_key(key_id) == value

# set timeout to 5 seconds, wait and then... it's gone:
keyutils.set_timeout(key_id, 5)
from time import sleep
sleep(6)
assert keyutils.request_key(name, ring) == None

Further examples can be found in the test subfolder.
