>>> from pskc import PSKC

>>> import datetime
>>> import sys
>>> import tempfile
>>> from binascii import a2b_hex
>>> from dateutil.tz import tzutc
>>> utc = tzutc()


Build a PSKC structure.

>>> pskc = PSKC()


Add a key with all attributes set.

>>> key = pskc.add_key(id='456', manufacturer='Manufacturer')
>>> key.id = '123'
>>> key.serial = '987654321'
>>> key.model = 'Model'
>>> key.issue_no = 2
>>> key.start_date = datetime.datetime(2006, 5, 1, 0, 0, tzinfo=utc)
>>> key.expiry_date = datetime.datetime(2014, 5, 31, 0, 0, tzinfo=utc)
>>> key.device_userid = 'uid=arthur, dc=arthurdejong, dc=org'
>>> key.crypto_module = 'CyrptoId'
>>> key.algorithm = 'urn:ietf:params:xml:ns:keyprov:pskc:totp'
>>> key.issuer = 'Issuer'
>>> key.key_profile = 'key profile id'
>>> key.key_reference = 'reference to some key'
>>> key.friendly_name = 'a friendly key'
>>> key.key_userid = 'cn=Arthur de Jong, dc=arthurdejong, dc=org'
>>> key.algorithm_suite = 'Clubs'
>>> key.challenge_encoding = 'DECIMAL'
>>> key.challenge_min_length = 6
>>> key.challenge_max_length = 8
>>> key.challenge_check = True
>>> key.response_encoding = 'DECIMAL'
>>> key.response_length = 8
>>> key.response_check = False
>>> key.counter = 0
>>> key.secret = a2b_hex('4e1790ba272406ba309c5a31')


Add policy information and a PIN.

>>> key.policy.key_usage.append('OTP')
>>> key.policy.key_usage.append(key.policy.KEY_USE_VERIFY)
>>> key.policy.start_date = datetime.datetime(2008, 5, 1, 0, 0, tzinfo=utc)
>>> key.policy.expiry_date = datetime.datetime(2012, 6, 13, 0, 0, tzinfo=utc)
>>> key.policy.number_of_transactions = 42
>>> key.policy.pin_key_id = 'pinID'
>>> key.policy.pin_usage = 'Local'
>>> key.policy.pin_max_failed_attemtps = 3
>>> key.policy.pin_min_length = 4
>>> key.policy.pin_max_length = 4
>>> key.policy.pin_encoding = 'DECIMAL'
>>> pin_key = pskc.add_key(id='pinID', secret='1234',
...     algorithm='urn:ietf:params:xml:ns:keyprov:pskc:pin',
...     response_encoding='DECIMAL', response_length=4)


Write the PSKC file (use temporary file to test passing file name as
argument).

>>> f = tempfile.NamedTemporaryFile()
>>> pskc.write(f.name)
>>> x = sys.stdout.write(open(f.name, 'r').read())
