9 * Restored workability of some command line options
10 * 2-pass DER encoding mode with very little memory footprint
23 * Fixed invalid behaviour where SET OF allowed multiple objects with the
24 same tag to be successfully decoded
25 * Fixed possibly invalid SET DER encoding where objects were not sorted
26 by tag, but by encoded representation
27 * ``Any`` does not allow empty data value now. Now it checks if it has
29 * ``SetOf`` is not treated as ready, if no value was set and minimum
30 bounds are greater than zero
31 * ``Any`` allows an ordinary ``Obj`` storing, without its forceful
32 encoded representation storage. That is required for CER encoding
33 mode, where we do not know in advance what encoding will be used
34 * ``ObjectIdentifier`` stores values as C unsigned long integer,
35 forbidding storage of huge integers, that must not be a problem in
37 * Initial support for so called ``evgen_mode``: event generation mode,
38 where no in-memory objects storing happens, giving ability to process
39 ASN.1 data without fully parsing it first. ``python -m pyderasn`` has
40 ``--evgen`` mode switcher
41 * Useful ``agg_octet_string`` that is able to streamingly decode string
42 from events of ``evgen_mode``, allowing strings retrieving without
43 copying them to memory first
44 * Initial experimental CER encoding mode, allowing streaming encoding of
45 the data directly to some writeable object
46 * Ability to use mmap-ed memoryviews to skip files loading to memory
47 * Ability to use memoryview as an input for \*Strings. If they are
48 mmap-ed, then you can encode any quantities of data streamingly
49 without copying to memory
55 * Fixed workability under Python 3.5. Previously only 2.7 and 3.6
62 * Python ``int()``'s accepts even more various non-decimal characters
63 than expected. Make validation fully strict in UTCTime and
64 GeneralizedTime, without relying on ``int()``
70 * UTCTime and GeneralizedTime allowed values to have plus sign in them,
71 passing int() check successfully. Prohibit that incorrect behaviour
72 * UTCTime and GeneralizedTime BER decoding support
73 * Faster UTCTime and GeneralizedTime decoding, and slightly better
75 * Workability under Cython
76 * Explicitly Check that all ObjectIdentifier arcs are non-negative
82 * ``.copy()`` method removed: ``copy.copy()`` is preferred way to copy
84 * Copies made previously with ``.copy()`` lacked ``.defined`` field,
86 * All objects are friendly to ``pickle`` libraries
87 * PrintableString has ``allow_asterisk`` and ``allow_ampersand``
89 * ``.hexencode()``, ``.hexdecode()`` and ``.hexdecod()`` methods
90 appeared, working with hexadecimal encoded data
96 * Convenient ``.decod()`` method, that raises if tail is not empty
97 * Control characters (like newlines) of text fields in pprinted output
99 * Ability to allow asterisk and ampersand characters
100 (``allow_asterisk``, ``allow_ampersand`` kwargs) in PrintableString,
101 that unfortunately could be met in X.509 certificates
107 * PEP-396 compatible module's ``__version__``
113 * Do not shadow underlying DecodeError during decoding of optional
120 * Forbid any later GNU GPL version autousage (project's licence now is
122 * Fix ``defines_by_path`` context option usage example
128 * Fix fallbacked ``colored()`` function workability,
129 if no ``termcolor`` is installed
135 * Fix empty ``--oids`` workability
141 * Ability to specify multiple OID mappings for pprinted output
142 (``oids`` keyword argument is renamed to ``oid_maps``)
148 * Minor decode speed improvements
149 * Much faster UTCTime/GeneralizedTime decoders
150 * Stricter UTCTime/GeneralizedTime DER encoding check: trailing zeroes
152 * Valid DER encoding of GeneralizedTime with microseconds: no trailing
159 * ObjectIdentifier has ``ber_encoded`` set to True, if non-normalized
161 * Preserve BER-related attributes during ``copy()``
167 * Added `COMPLI <https://github.com/YuryStrozhevsky/asn1-test-suite>`__
168 ASN.1:2008 test suite. PyDERASN passes it (except for REAL values),
169 but it is more strict sometimes and aimed to be compliant with X.690-201508
170 * Check for arc values normalization in ObjectIdentifier.
171 Forbid non-normalized in DER encoding
177 * ``ctx`` parameter can be safely used in .decode() and won't be muted
178 * PP nametuple contains reference to the ASN1Obj itself
179 * ``colonize_hex`` function useful for pretty printing
180 * Integer values are also pretty printed in hexadecimal form
186 * All errors are inherited from ASN1Error class
187 * NumericString/PrintableString has ``allowable_chars`` property holding
188 all allowed characters
194 * Fix NumericString: space is allowed character
195 * Strict PrintableString sanitizing
201 * Removed ``lenindef``, ``ber_encoded`` attributes from the Choice --
202 they must be taken from underlying value, as Choice does not have its
204 * Do not yield extra EOC PP for Any, having indefinite length encoding
205 and containing autodecoded DEFINED BY value
211 * ``bered`` attribute, meaning if object has BER-specific encoding, is
212 renamed to ``ber_encoded``
213 * ``bered`` attribute is replace with property showing if any of
214 underlying values are BER-encoded. If value has length indefinite
215 encoded explicit tag, value, if value contains BER-related encoding,
216 or if it contains other objects that are ``bered``, then it is ``bered``
222 * Default value is checked also for Sets, not for Sequences only
223 * **Incompatible** change: defaulted values in Sequence/Set are always
224 strictly checked, unless ``allow_default_values`` context option is
225 set. ``strict_default_existence`` option disappeared
226 * Strict Set/Set Of's values ordering check
232 * Additional encoding validness check: explicit tag must contain exactly
233 one object inside. Throw DecodeError otherwise
234 * ``allow_expl_oob`` context and command-line options allow skipping of
241 * DecodeError's decode paths are separated with ``:``, instead of ``.``,
242 because of colliding with dots in OIDs
243 * Ability to print element decode paths with ``--print-decode-path``
244 command line option (and corresponding keyword argument)
245 * Ability to print tree's branch specified with ``--decode-path-only``
251 * Fix possible uncaught TypeError in Py2 with zero bytes inside the value
252 * Fix SequenceOf/SetOf raising BoundsError instead of DecodeError
258 * Fix uncaught UTCTime/GeneralizedTime decode error when dealing with
259 non ASCII-encoded values
265 * Fix long-standing bug with explicitly tagged objects inside the
266 Choice. If Choice had explicitly tagged value, then its ``.tlvlen``
267 reports the size without taking value's explicit tag in advance
268 * Add ``.fulllen`` and ``.fulloffset`` properties for all objects
274 * SEQUENCE's values are printed with field's name. Previously there was
275 the following output::
277 AlgorithmIdentifier SEQUENCE[OBJECT IDENTIFIER 1.3.14.3.2.26, [UNIV 5] ANY 0500 OPTIONAL]
281 AlgorithmIdentifier SEQUENCE[algorithm: OBJECT IDENTIFIER 1.3.14.3.2.26; parameters: [UNIV 5] ANY 0500 OPTIONAL]
282 * Fixed EOC (Unicode character) repr printing issues under Python2
288 BER's EOC is explicitly shown during pprinting. Following notation::
290 15-2 [0,0,1576]-4 . content: [0] EXPLICIT [UNIV 16] ANY
294 15-2∞ [0,0,1576]∞ . content: [0] EXPLICIT [UNIV 16] ANY
296 1587 [1,1, 0] . content: BER EOC
297 1589 [1,1, 0] . content: EXPLICIT BER EOC
303 * BER decoding support
304 * BitString's ''H notation support
305 * ``termcolor`` package is included in the tarball
311 * Ability to set values during Sequence initialization
317 * Fix TagMismatch exception completeness during Choice and Set decoding.
318 Previously we will loose offset and decode_path information about
319 concrete TagMismatched entity
325 * Strict NumericString's value sanitation
326 * Invalid encoding in string types will raise ``DecodeError`` exception,
327 instead of ``Unicode*Error``
328 * Fixed DecodePathDefBy workability with Python 2.x
334 * Fix nasty BitString decoding bug: it could fail when data follows
335 encoded BitString value. There weren't any problems when BitString is
336 at the end of Sequence
342 * Slightly corrected colours, now visible on white background
348 * Fix bug related to DecodeError showing with DecodePathDefBy entities
349 * Respect ``NO_COLOR`` environment variable
355 * :py:func:`pyderasn.decode_path_defby` is replaced with
356 :py:class:`pyderasn.DecodePathDefBy`
357 * Ability to turn colourized terminal output by calling
358 ``pprint(..., with_colours=True)``. You will need
359 `termcolor package <https://pypi.org/project/termcolor/>`__
365 * Fixed invalid offset calculation when dealing with DEFINED BY objects
372 * BIT STRINGs can also be :ref:`DEFINED BY <definedby>`
373 * Decoding process can be governed with optional :ref:`ctx <ctx>`
374 keyword argument to ``decode()`` method
375 * :ref:`defines_by_path <defines_by_path_ctx>` option is now
376 :ref:`decode context <ctx>` option, not a keyword argument
377 * Ability to do ``strict validation``
378 of defaulted values met in sequence, raising an exception
384 Ability to skip specified number of bytes (``--skip``) in command line
391 * Generic decoder's schema and pretty printer
392 (:py:func:`pyderasn.generic_decoder`) can be used in libraries
393 * Ability to specify :ref:`defines_by_path <defines_by_path_ctx>`
394 during command line invocation
400 Ability to automatically decode :ref:`DEFINED BY <definedby>` fields
407 Removed ``__lt__``/``__eq__`` from base class, as pylint likes it.
413 Full rich comparison operators added.
420 Trivial README addition.
