8 * Fixed invalid behaviour where SET OF allowed multiple objects with the
9 same tag to be successfully decoded
10 * Fixed possibly invalid SET DER encoding where objects were not sorted
11 by tag, but by encoded representation
12 * ``Any`` does not allow empty data value now. Now it checks if it has
14 * ``SetOf`` is not treated as ready, if no value was set and minimum
15 bounds are greater than zero
16 * ``Any`` allows an ordinary ``Obj`` storing, without its forceful
17 encoded representation storage. That is required for CER encoding
18 mode, where we do not know in advance what encoding will be used
19 * ``ObjectIdentifier`` stores values as C unsigned long integer,
20 forbidding storage of huge integers, that must not be a problem in
22 * Initial support for so called ``evgen_mode``: event generation mode,
23 where no in-memory objects storing happens, giving ability to process
24 ASN.1 data without fully parsing it first. ``python -m pyderasn`` has
25 ``--evgen`` mode switcher
26 * Useful ``agg_octet_string`` that is able to streamingly decode string
27 from events of ``evgen_mode``, allowing strings retrieving without
28 copying them to memory first
29 * Initial experimental CER encoding mode, allowing streaming encoding of
30 the data directly to some writeable object
31 * Ability to use mmap-ed memoryviews to skip files loading to memory
32 * Ability to use memoryview as an input for \*Strings. If they are
33 mmap-ed, then you can encode any quantities of data streamingly
34 without copying to memory
40 * Fixed workability under Python 3.5. Previously only 2.7 and 3.6
47 * Python ``int()``'s accepts even more various non-decimal characters
48 than expected. Make validation fully strict in UTCTime and
49 GeneralizedTime, without relying on ``int()``
55 * UTCTime and GeneralizedTime allowed values to have plus sign in them,
56 passing int() check successfully. Prohibit that incorrect behaviour
57 * UTCTime and GeneralizedTime BER decoding support
58 * Faster UTCTime and GeneralizedTime decoding, and slightly better
60 * Workability under Cython
61 * Explicitly Check that all ObjectIdentifier arcs are non-negative
67 * ``.copy()`` method removed: ``copy.copy()`` is preferred way to copy
69 * Copies made previously with ``.copy()`` lacked ``.defined`` field,
71 * All objects are friendly to ``pickle`` libraries
72 * PrintableString has ``allow_asterisk`` and ``allow_ampersand``
74 * ``.hexencode()``, ``.hexdecode()`` and ``.hexdecod()`` methods
75 appeared, working with hexadecimal encoded data
81 * Convenient ``.decod()`` method, that raises if tail is not empty
82 * Control characters (like newlines) of text fields in pprinted output
84 * Ability to allow asterisk and ampersand characters
85 (``allow_asterisk``, ``allow_ampersand`` kwargs) in PrintableString,
86 that unfortunately could be met in X.509 certificates
92 * PEP-396 compatible module's ``__version__``
98 * Do not shadow underlying DecodeError during decoding of optional
105 * Forbid any later GNU GPL version autousage (project's licence now is
107 * Fix ``defines_by_path`` context option usage example
113 * Fix fallbacked ``colored()`` function workability,
114 if no ``termcolor`` is installed
120 * Fix empty ``--oids`` workability
126 * Ability to specify multiple OID mappings for pprinted output
127 (``oids`` keyword argument is renamed to ``oid_maps``)
133 * Minor decode speed improvements
134 * Much faster UTCTime/GeneralizedTime decoders
135 * Stricter UTCTime/GeneralizedTime DER encoding check: trailing zeroes
137 * Valid DER encoding of GeneralizedTime with microseconds: no trailing
144 * ObjectIdentifier has ``ber_encoded`` set to True, if non-normalized
146 * Preserve BER-related attributes during ``copy()``
152 * Added `COMPLI <https://github.com/YuryStrozhevsky/asn1-test-suite>`__
153 ASN.1:2008 test suite. PyDERASN passes it (except for REAL values),
154 but it is more strict sometimes and aimed to be compliant with X.690-201508
155 * Check for arc values normalization in ObjectIdentifier.
156 Forbid non-normalized in DER encoding
162 * ``ctx`` parameter can be safely used in .decode() and won't be muted
163 * PP nametuple contains reference to the ASN1Obj itself
164 * ``colonize_hex`` function useful for pretty printing
165 * Integer values are also pretty printed in hexadecimal form
171 * All errors are inherited from ASN1Error class
172 * NumericString/PrintableString has ``allowable_chars`` property holding
173 all allowed characters
179 * Fix NumericString: space is allowed character
180 * Strict PrintableString sanitizing
186 * Removed ``lenindef``, ``ber_encoded`` attributes from the Choice --
187 they must be taken from underlying value, as Choice does not have its
189 * Do not yield extra EOC PP for Any, having indefinite length encoding
190 and containing autodecoded DEFINED BY value
196 * ``bered`` attribute, meaning if object has BER-specific encoding, is
197 renamed to ``ber_encoded``
198 * ``bered`` attribute is replace with property showing if any of
199 underlying values are BER-encoded. If value has length indefinite
200 encoded explicit tag, value, if value contains BER-related encoding,
201 or if it contains other objects that are ``bered``, then it is ``bered``
207 * Default value is checked also for Sets, not for Sequences only
208 * **Incompatible** change: defaulted values in Sequence/Set are always
209 strictly checked, unless ``allow_default_values`` context option is
210 set. ``strict_default_existence`` option disappeared
211 * Strict Set/Set Of's values ordering check
217 * Additional encoding validness check: explicit tag must contain exactly
218 one object inside. Throw DecodeError otherwise
219 * ``allow_expl_oob`` context and command-line options allow skipping of
226 * DecodeError's decode paths are separated with ``:``, instead of ``.``,
227 because of colliding with dots in OIDs
228 * Ability to print element decode paths with ``--print-decode-path``
229 command line option (and corresponding keyword argument)
230 * Ability to print tree's branch specified with ``--decode-path-only``
236 * Fix possible uncaught TypeError in Py2 with zero bytes inside the value
237 * Fix SequenceOf/SetOf raising BoundsError instead of DecodeError
243 * Fix uncaught UTCTime/GeneralizedTime decode error when dealing with
244 non ASCII-encoded values
250 * Fix long-standing bug with explicitly tagged objects inside the
251 Choice. If Choice had explicitly tagged value, then its ``.tlvlen``
252 reports the size without taking value's explicit tag in advance
253 * Add ``.fulllen`` and ``.fulloffset`` properties for all objects
259 * SEQUENCE's values are printed with field's name. Previously there was
260 the following output::
262 AlgorithmIdentifier SEQUENCE[OBJECT IDENTIFIER 1.3.14.3.2.26, [UNIV 5] ANY 0500 OPTIONAL]
266 AlgorithmIdentifier SEQUENCE[algorithm: OBJECT IDENTIFIER 1.3.14.3.2.26; parameters: [UNIV 5] ANY 0500 OPTIONAL]
267 * Fixed EOC (Unicode character) repr printing issues under Python2
273 BER's EOC is explicitly shown during pprinting. Following notation::
275 15-2 [0,0,1576]-4 . content: [0] EXPLICIT [UNIV 16] ANY
279 15-2∞ [0,0,1576]∞ . content: [0] EXPLICIT [UNIV 16] ANY
281 1587 [1,1, 0] . content: BER EOC
282 1589 [1,1, 0] . content: EXPLICIT BER EOC
288 * BER decoding support
289 * BitString's ''H notation support
290 * ``termcolor`` package is included in the tarball
296 * Ability to set values during Sequence initialization
302 * Fix TagMismatch exception completeness during Choice and Set decoding.
303 Previously we will loose offset and decode_path information about
304 concrete TagMismatched entity
310 * Strict NumericString's value sanitation
311 * Invalid encoding in string types will raise ``DecodeError`` exception,
312 instead of ``Unicode*Error``
313 * Fixed DecodePathDefBy workability with Python 2.x
319 * Fix nasty BitString decoding bug: it could fail when data follows
320 encoded BitString value. There weren't any problems when BitString is
321 at the end of Sequence
327 * Slightly corrected colours, now visible on white background
333 * Fix bug related to DecodeError showing with DecodePathDefBy entities
334 * Respect ``NO_COLOR`` environment variable
340 * :py:func:`pyderasn.decode_path_defby` is replaced with
341 :py:class:`pyderasn.DecodePathDefBy`
342 * Ability to turn colourized terminal output by calling
343 ``pprint(..., with_colours=True)``. You will need
344 `termcolor package <https://pypi.org/project/termcolor/>`__
350 * Fixed invalid offset calculation when dealing with DEFINED BY objects
357 * BIT STRINGs can also be :ref:`DEFINED BY <definedby>`
358 * Decoding process can be governed with optional :ref:`ctx <ctx>`
359 keyword argument to ``decode()`` method
360 * :ref:`defines_by_path <defines_by_path_ctx>` option is now
361 :ref:`decode context <ctx>` option, not a keyword argument
362 * Ability to do ``strict validation``
363 of defaulted values met in sequence, raising an exception
369 Ability to skip specified number of bytes (``--skip``) in command line
376 * Generic decoder's schema and pretty printer
377 (:py:func:`pyderasn.generic_decoder`) can be used in libraries
378 * Ability to specify :ref:`defines_by_path <defines_by_path_ctx>`
379 during command line invocation
385 Ability to automatically decode :ref:`DEFINED BY <definedby>` fields
392 Removed ``__lt__``/``__eq__`` from base class, as pylint likes it.
398 Full rich comparison operators added.
405 Trivial README addition.
