>>> from binascii import a2b_hex

Sadly we cannot test --help and --version properly because argparse calls
exit(0) which doctest does not like.
>>> sys.argv = shlex.split('csv2pskc --help')
>>> main() # doctest: +IGNORE_EXCEPTION_DETAIL
Traceback (most recent call last):

We can output a PSKC file with some simple data from a CSV file. The columns
in the CSV file refer to names of PSKC properties.
>>> f = tempfile.NamedTemporaryFile('w+t')
>>> x = f.write('''

As long as it is in a file (does not work on stdin) the script should also
automatically pick up tab-separated files.

</pskc:KeyPackage>
</pskc:KeyContainer>
We can use the --columns option to override using the first row to specify
the key properties.
>>> f = tempfile.NamedTemporaryFile('w+t')
>>> x = f.write('''
... nr,key,start date,info

Alternatively, we can provide a mapping for column names found in the CSV
file to key properties.
>>> f = tempfile.NamedTemporaryFile('w+t')
>>> x = f.write('''
... nr,key,start date,info
... 121232,6848464354638468468835346896846846846846,2017-04-01,something

We can also set global key properties with the --set option to apply values
to all keys in the PSKC file:
>>> f = tempfile.NamedTemporaryFile('w+t')
>>> x = f.write('''
... id+serial,secret
... 987654321,7c613e9c2194ff7da7f4770ab2ed712111fcbe95

... '''.lstrip())
>>> f.flush()
>>> sys.argv = [
... 'csv2pskc', f.name,
... '--set', 'manufacturer=TokenVendor', '--set', 'issuer=TokenIssuer']
>>> main() #doctest: +REPORT_UDIFF +NORMALIZE_WHITESPACE
<?xml version="1.0" encoding="UTF-8"?>
<pskc:KeyContainer xmlns:pskc="urn:ietf:params:xml:ns:keyprov:pskc" Version="1.0">

</pskc:Data>
</pskc:Key>
</pskc:KeyPackage>
</pskc:KeyContainer>
The --skip-rows option can be used to either not use the first row to denote
the key properties that are set (in which case the --columns option is
mandatory) or skip more rows at the beginning of the file.
>>> f = tempfile.NamedTemporaryFile('w+t')
>>> x = f.write('''
... 987654321,7c613e9c2194ff7da7f4770ab2ed712111fcbe95

We can encrypt the resulting PSKC file with a passphrase.
>>> f = tempfile.NamedTemporaryFile('w+t')
>>> x = f.write('''

Alternatively we can switch from passphrase-based encryption to key-based
encryption.
