This Python library handles Portable Symmetric Key Container (PSKC) files as defined in RFC 6030. PSKC files are used to transport and provision symmetric keys (seed files) to different types of crypto modules, commonly one-time password tokens or other authentication devices.

This module can be used to extract keys from PSKC files for use in an OTP authentication system. The module can also be used for authoring PSKC files.

---

The following prints all keys, decrypting the file using a password:

from pskc import PSKC
pskc = PSKC('seedfile.pskcxml')
pskc.encryption.derive_key('password')
for key in pskc.keys:
    print('%s %s' % (key.serial, b2a_hex(key.secret)))

Creating an encrypted PSKC file can be done using:

pskc = PSKC()
pskc.encryption.setup_pbkdf2('password')
key = pskc.add_key(
    id='456', secret='987654321', manufacturer='Manufacturer',
    algorithm = 'urn:ietf:params:xml:ns:keyprov:pskc:hotp')
pskc.write('output.pskcxml')

The module should be able to handle most common PSKC files. More information is available in the online documentation.

Feedback and patches are more than welcome. Please use the python-pskc-users mailing list.
