8 * Fixed workability under Python 3.5. Previously only 2.7 and 3.6
15 * Python ``int()``'s accepts even more various non-decimal characters
16 than expected. Make validation fully strict in UTCTime and
17 GeneralizedTime, without relying on ``int()``
23 * UTCTime and GeneralizedTime allowed values to have plus sign in them,
24 passing int() check successfully. Prohibit that incorrect behaviour
25 * UTCTime and GeneralizedTime BER decoding support
26 * Faster UTCTime and GeneralizedTime decoding, and slightly better
28 * Workability under Cython
29 * Explicitly Check that all ObjectIdentifier arcs are non-negative
35 * ``.copy()`` method removed: ``copy.copy()`` is preferred way to copy
37 * Copies made previously with ``.copy()`` lacked ``.defined`` field,
39 * All objects are friendly to ``pickle`` libraries
40 * PrintableString has ``allow_asterisk`` and ``allow_ampersand``
42 * ``.hexencode()``, ``.hexdecode()`` and ``.hexdecod()`` methods
43 appeared, working with hexadecimal encoded data
49 * Convenient ``.decod()`` method, that raises if tail is not empty
50 * Control characters (like newlines) of text fields in pprinted output
52 * Ability to allow asterisk and ampersand characters
53 (``allow_asterisk``, ``allow_ampersand`` kwargs) in PrintableString,
54 that unfortunately could be met in X.509 certificates
60 * PEP-396 compatible module's ``__version__``
66 * Do not shadow underlying DecodeError during decoding of optional
73 * Forbid any later GNU GPL version autousage (project's licence now is
75 * Fix ``defines_by_path`` context option usage example
81 * Fix fallbacked ``colored()`` function workability,
82 if no ``termcolor`` is installed
88 * Fix empty ``--oids`` workability
94 * Ability to specify multiple OID mappings for pprinted output
95 (``oids`` keyword argument is renamed to ``oid_maps``)
101 * Minor decode speed improvements
102 * Much faster UTCTime/GeneralizedTime decoders
103 * Stricter UTCTime/GeneralizedTime DER encoding check: trailing zeroes
105 * Valid DER encoding of GeneralizedTime with microseconds: no trailing
112 * ObjectIdentifier has ``ber_encoded`` set to True, if non-normalized
114 * Preserve BER-related attributes during ``copy()``
120 * Added `COMPLI <https://github.com/YuryStrozhevsky/asn1-test-suite>`__
121 ASN.1:2008 test suite. PyDERASN passes it (except for REAL values),
122 but it is more strict sometimes and aimed to be compliant with X.690-201508
123 * Check for arc values normalization in ObjectIdentifier.
124 Forbid non-normalized in DER encoding
130 * ``ctx`` parameter can be safely used in .decode() and won't be muted
131 * PP nametuple contains reference to the ASN1Obj itself
132 * ``colonize_hex`` function useful for pretty printing
133 * Integer values are also pretty printed in hexadecimal form
139 * All errors are inherited from ASN1Error class
140 * NumericString/PrintableString has ``allowable_chars`` property holding
141 all allowed characters
147 * Fix NumericString: space is allowed character
148 * Strict PrintableString sanitizing
154 * Removed ``lenindef``, ``ber_encoded`` attributes from the Choice --
155 they must be taken from underlying value, as Choice does not have its
157 * Do not yield extra EOC PP for Any, having indefinite length encoding
158 and containing autodecoded DEFINED BY value
164 * ``bered`` attribute, meaning if object has BER-specific encoding, is
165 renamed to ``ber_encoded``
166 * ``bered`` attribute is replace with property showing if any of
167 underlying values are BER-encoded. If value has length indefinite
168 encoded explicit tag, value, if value contains BER-related encoding,
169 or if it contains other objects that are ``bered``, then it is ``bered``
175 * Default value is checked also for Sets, not for Sequences only
176 * **Incompatible** change: defaulted values in Sequence/Set are always
177 strictly checked, unless ``allow_default_values`` context option is
178 set. ``strict_default_existence`` option disappeared
179 * Strict Set/Set Of's values ordering check
185 * Additional encoding validness check: explicit tag must contain exactly
186 one object inside. Throw DecodeError otherwise
187 * ``allow_expl_oob`` context and command-line options allow skipping of
194 * DecodeError's decode paths are separated with ``:``, instead of ``.``,
195 because of colliding with dots in OIDs
196 * Ability to print element decode paths with ``--print-decode-path``
197 command line option (and corresponding keyword argument)
198 * Ability to print tree's branch specified with ``--decode-path-only``
204 * Fix possible uncaught TypeError in Py2 with zero bytes inside the value
205 * Fix SequenceOf/SetOf raising BoundsError instead of DecodeError
211 * Fix uncaught UTCTime/GeneralizedTime decode error when dealing with
212 non ASCII-encoded values
218 * Fix long-standing bug with explicitly tagged objects inside the
219 Choice. If Choice had explicitly tagged value, then its ``.tlvlen``
220 reports the size without taking value's explicit tag in advance
221 * Add ``.fulllen`` and ``.fulloffset`` properties for all objects
227 * SEQUENCE's values are printed with field's name. Previously there was
228 the following output::
230 AlgorithmIdentifier SEQUENCE[OBJECT IDENTIFIER 1.3.14.3.2.26, [UNIV 5] ANY 0500 OPTIONAL]
234 AlgorithmIdentifier SEQUENCE[algorithm: OBJECT IDENTIFIER 1.3.14.3.2.26; parameters: [UNIV 5] ANY 0500 OPTIONAL]
235 * Fixed EOC (Unicode character) repr printing issues under Python2
241 BER's EOC is explicitly shown during pprinting. Following notation::
243 15-2 [0,0,1576]-4 . content: [0] EXPLICIT [UNIV 16] ANY
247 15-2∞ [0,0,1576]∞ . content: [0] EXPLICIT [UNIV 16] ANY
249 1587 [1,1, 0] . content: BER EOC
250 1589 [1,1, 0] . content: EXPLICIT BER EOC
256 * BER decoding support
257 * BitString's ''H notation support
258 * ``termcolor`` package is included in the tarball
264 * Ability to set values during Sequence initialization
270 * Fix TagMismatch exception completeness during Choice and Set decoding.
271 Previously we will loose offset and decode_path information about
272 concrete TagMismatched entity
278 * Strict NumericString's value sanitation
279 * Invalid encoding in string types will raise ``DecodeError`` exception,
280 instead of ``Unicode*Error``
281 * Fixed DecodePathDefBy workability with Python 2.x
287 * Fix nasty BitString decoding bug: it could fail when data follows
288 encoded BitString value. There weren't any problems when BitString is
289 at the end of Sequence
295 * Slightly corrected colours, now visible on white background
301 * Fix bug related to DecodeError showing with DecodePathDefBy entities
302 * Respect ``NO_COLOR`` environment variable
308 * :py:func:`pyderasn.decode_path_defby` is replaced with
309 :py:class:`pyderasn.DecodePathDefBy`
310 * Ability to turn colourized terminal output by calling
311 ``pprint(..., with_colours=True)``. You will need
312 `termcolor package <https://pypi.org/project/termcolor/>`__
318 * Fixed invalid offset calculation when dealing with DEFINED BY objects
325 * BIT STRINGs can also be :ref:`DEFINED BY <definedby>`
326 * Decoding process can be governed with optional :ref:`ctx <ctx>`
327 keyword argument to ``decode()`` method
328 * :ref:`defines_by_path <defines_by_path_ctx>` option is now
329 :ref:`decode context <ctx>` option, not a keyword argument
330 * Ability to do ``strict validation``
331 of defaulted values met in sequence, raising an exception
337 Ability to skip specified number of bytes (``--skip``) in command line
344 * Generic decoder's scheme and pretty printer
345 (:py:func:`pyderasn.generic_decoder`) can be used in libraries
346 * Ability to specify :ref:`defines_by_path <defines_by_path_ctx>`
347 during command line invocation
353 Ability to automatically decode :ref:`DEFINED BY <definedby>` fields
360 Removed ``__lt__``/``__eq__`` from base class, as pylint likes it.
366 Full rich comparison operators added.
373 Trivial README addition.
