* Get files ready for 0.2 release0.2Arthur de Jong2014-06-191-1/+1
|
* Only catch normal exceptionsArthur de Jong2014-06-191-1/+1
|
* Remove unused importArthur de Jong2014-06-181-2/+0
|
* PEP8 fixArthur de Jong2014-06-171-2/+2
|
* Remove __str__ from exceptionArthur de Jong2014-06-171-3/+1
| | | | | The message property has been deprecated as of Python 2.6 and printing the first argument is the default.
* Simplify finding ElementTree implementationArthur de Jong2014-06-151-10/+1
| | | | | These are the only ElementTree implementations that have been tested to provide the needed functionality (mostly namespaces).
* Refactor out some functions to parseArthur de Jong2014-06-153-26/+26
| | | | | This introduces the getint() and getbool() functions in parse to avoid some code duplication.
* Add support for setting secretArthur de Jong2014-06-151-24/+39
| | | | | | This supports setters for the secret, counter, time_offset, time_interval and time_drift properties. Setting these values stores the values unencrypted internally.
* Support PBKDF2 PRF argumentArthur de Jong2014-06-151-5/+9
| | | | | Support specifying a pseudorandom function for PBKDF2 key derivation. It currently supports any HMAC that the MAC checking also supports.
* Provide a get_hmac() functionArthur de Jong2014-06-151-11/+16
| | | | | Refactor the functionality to find an HMAC function into a separate function.
* Raise exception when MAC validation failsArthur de Jong2014-06-142-21/+24
| | | | | | | | | This changes the way the check() function works to raise an exception when the MAC is not correct. The MAC is also now always checked before attempting decryption. This also renames the internal DataType.value property to a get_value() method for clarity.
* Handle missing MAC algorithm properlyArthur de Jong2014-06-141-1/+2
|
* Automatically support all MACs in hashlibArthur de Jong2014-06-141-5/+15
| | | | | This uses the name of the hash to automatically get the correct hash object from Python's hashlib.
* Support various ElementTree implementationsArthur de Jong2014-06-142-3/+18
| | | | | | | | | | | When using a recent enough lxml, even Python 2.6 should work now. The most important requirement is that the findall() function supports the namespaces argument. This also now catches all exceptions when parsing the PSKC file fails and wraps it in ParseError because various implementations raise different exceptions, even between versions (Python 2.6's ElementTree raises ExpatError, lxml raises XMLSyntaxError).
* Have parse module provide find() functionsArthur de Jong2014-06-146-108/+105
| | | | | | | | This changes the parse module functions to better match the ElementTree API and extends it with findint(), findtime() and findbin(). It also passes the namespaces to all calls that require it without duplicating this throughout the normal code.
* Use get() instead of attrib.get() (shorter)Arthur de Jong2014-06-145-38/+38
|
* Support kw-tripledes decryptionArthur de Jong2014-05-311-0/+6
| | | | | This adds support for key unwrapping using the RFC 3217 Triple DES key wrap algorithm if the PSKC file uses this.
* Implement RFC 3217 Triple DES key wrappingArthur de Jong2014-05-311-0/+67
|
* Support kw-aes128, kw-aes192 and kw-aes256Arthur de Jong2014-05-301-0/+9
| | | | | This adds support for key unwrapping using the RFC 3394 or RFC 5649 algorithm if the PSKC file uses this.
* Implement padding as specified in RFC 5649Arthur de Jong2014-05-301-25/+61
| | | | This adds a pad argument with which padding can be forced or disabled.
* Allow speciying an initial value for key wrappingArthur de Jong2014-05-301-6/+20
|
* Provide an RFC 3394 AES key wrapping algorithmArthur de Jong2014-05-302-0/+78
| | | | This also introduces an EncryptionError exception.
* Always put a space between RFC and numberArthur de Jong2014-05-291-7/+7
|
* Support Tripple DES decryptionArthur de Jong2014-05-291-0/+8
|
* Raise exception when key derivation failsArthur de Jong2014-05-292-2/+16
| | | | This also renames the internal function that implements the derivation.
* Add test for missing key encryption algorithmArthur de Jong2014-05-292-8/+13
| | | | | This also introduces a toplevel PSKCError exception that all exceptions have as parent.
* Support more AES-CBC encryption schemesArthur de Jong2014-05-291-4/+8
| | | | | This also moves the crypto imports to the places where they are used to avoid a depenency on pycrypto if no encryption is used.
* Add a function for adding a new keyArthur de Jong2014-05-252-1/+16
|
* Consistency improvementArthur de Jong2014-05-251-2/+2
|
* Support creating an empty PSKC instanceArthur de Jong2014-05-251-6/+9
|
* Be more lenient in accepting algorithmsArthur de Jong2014-05-252-16/+3
|
* Code simplificationArthur de Jong2014-05-251-9/+5
|
* Raise an exception if decryption failsArthur de Jong2014-05-252-2/+17
|
* Make decryption code better readableArthur de Jong2014-05-251-5/+9
|
* Raise exceptions on some parsing problemsArthur de Jong2014-05-232-2/+44
|
* Use pskcxml as file name extensionArthur de Jong2014-05-231-1/+1
| | | | This is the extension that is suggested in RFC6030.
* Add missing policy constantArthur de Jong2014-05-191-0/+3
|
* Fix attribute name in docstringArthur de Jong2014-05-191-1/+1
|
* Fix module descriptionArthur de Jong2014-04-191-2/+1
|
* Move PSKC class to toplevel moduleArthur de Jong2014-04-192-42/+44
| | | | This also splits the parsing to a parse() function for consistency.
* Provide pskc.key docstringsArthur de Jong2014-04-191-47/+114
| | | | | | | | | This documents most of the information that is available per key and adds a few other minor cosmetic changes. This also re-organises the key properties to be in a slightly more logical order and renames the userid key property to key_userid to more clearly distinguish it from device_userid.
* Provide pskc.parse docstringsArthur de Jong2014-04-191-1/+19
| | | | | This documents most of the API of the parsing functions and the PSKC class.
* Complete pskc.policy docstringsArthur de Jong2014-04-191-2/+4
| | | | Also contains small consistency improvement.
* Provide pskc.mac docstringsArthur de Jong2014-04-191-8/+34
| | | | This also hides two properties that are not part of the public API.
* Provide pskc.encryption docstringsArthur de Jong2014-04-191-5/+41
| | | | This documents classes in the pskc.encryption module.
* Move Key class to separate moduleArthur de Jong2014-04-194-188/+239
| | | | This also allows re-organising the imports a bit.
* Add initial setup scriptArthur de Jong2014-04-161-2/+22
|
* Use slightly clearer namesArthur de Jong2014-04-161-4/+4
|
* Implement PBKDF2 key derivationArthur de Jong2014-04-131-0/+64
| | | | | This supports deriving the key from a passphrase and information present in the DerivedKey and PBKDF2-params XML elements.
* Add id attribute from EncryptionKeyArthur de Jong2014-04-131-2/+5
