>>> from binascii import b2a_hex
>>> def tostr(x):
...     return str(x.decode())
>>> def decode(f):
...     return lambda x: tostr(f(x))
>>> b2a_hex = decode(b2a_hex)

>>> from pskc import PSKC


This tests the most minimal valid PSKC file with one empty key.

>>> try:
...     from StringIO import StringIO
... except ImportError:
...     from io import StringIO
>>> minimal_pskc = StringIO('''
... <?xml version="1.0"?>
... <KeyContainer xmlns="urn:ietf:params:xml:ns:keyprov:pskc" Version="1.0">
...   <KeyPackage/>
... </KeyContainer>
... '''.strip())
>>> pskc = PSKC(minimal_pskc)
>>> [key.id for key in pskc.keys]
[None]


Check creation of empty PSKC structure and adding an empty key to the list.

>>> pskc = PSKC()
>>> key = pskc.add_key(id='123')
>>> key.id
'123'
>>> key.secret is None
True


Adding a key with unknown attributes raises an error.

>>> key = pskc.add_key(foo='bar')
Traceback (most recent call last):
    ...
AttributeError


Setting secret, counter, etc. also works

>>> key = pskc.add_key(secret='VERYSECRET')
>>> key.counter = 10
>>> key.secret
'VERYSECRET'
>>> key.counter
10


Load an PSKC file with an odd namespace.

>>> pskc = PSKC('tests/odd-namespace.pskcxml')
>>> pskc.version
'1.0'
>>> pskc.id
'exampleID1'
>>> key = pskc.keys[0]
>>> key.id
'12345678'
>>> key.issuer
'Issuer-A'
>>> tostr(key.secret)
'1234'


Load a PSKC file that uses the xenc11 namespace for the PBKDF2 parameters.

>>> pskc = PSKC('tests/SampleFullyQualifiedNS.xml')
>>> pskc.encryption.key_name
'PassPhrase'
>>> pskc.encryption.derive_key('3FCA3158035072D6')
>>> key = pskc.keys[0]
>>> b2a_hex(key.secret)
'09fbecfd0bf47910839e2eb05ffa10b95cd0390950ce32ab790583ed134171e0'
>>> key.check()
True
