9 * Fix DEFINED BY pprinting when invoking as __main__ module
10 * Integer has ``tohex()`` for getting hexadecimal representation of its value
17 * SEQUENCE/SET fully performs default value existence validation in
18 evgen mode, by the cost of DEFAULTed value full decoding. That should
19 not be the problem, as DEFAULTs are relatively small in practice. Now
20 evgen mode has the same DER validation strictness as an ordinary one
27 * Restored workability of some command line options
28 * 2-pass DER encoding mode with very little memory footprint
41 * Fixed invalid behaviour where SET OF allowed multiple objects with the
42 same tag to be successfully decoded
43 * Fixed possibly invalid SET DER encoding where objects were not sorted
44 by tag, but by encoded representation
45 * ``Any`` does not allow empty data value now. Now it checks if it has
47 * ``SetOf`` is not treated as ready, if no value was set and minimum
48 bounds are greater than zero
49 * ``Any`` allows an ordinary ``Obj`` storing, without its forceful
50 encoded representation storage. That is required for CER encoding
51 mode, where we do not know in advance what encoding will be used
52 * ``ObjectIdentifier`` stores values as C unsigned long integer,
53 forbidding storage of huge integers, that must not be a problem in
55 * Initial support for so called ``evgen_mode``: event generation mode,
56 where no in-memory objects storing happens, giving ability to process
57 ASN.1 data without fully parsing it first. ``python -m pyderasn`` has
58 ``--evgen`` mode switcher
59 * Useful ``agg_octet_string`` that is able to streamingly decode string
60 from events of ``evgen_mode``, allowing strings retrieving without
61 copying them to memory first
62 * Initial experimental CER encoding mode, allowing streaming encoding of
63 the data directly to some writeable object
64 * Ability to use mmap-ed memoryviews to skip files loading to memory
65 * Ability to use memoryview as an input for \*Strings. If they are
66 mmap-ed, then you can encode any quantities of data streamingly
67 without copying to memory
73 * Fixed workability under Python 3.5. Previously only 2.7 and 3.6
80 * Python ``int()``'s accepts even more various non-decimal characters
81 than expected. Make validation fully strict in UTCTime and
82 GeneralizedTime, without relying on ``int()``
88 * UTCTime and GeneralizedTime allowed values to have plus sign in them,
89 passing int() check successfully. Prohibit that incorrect behaviour
90 * UTCTime and GeneralizedTime BER decoding support
91 * Faster UTCTime and GeneralizedTime decoding, and slightly better
93 * Workability under Cython
94 * Explicitly Check that all ObjectIdentifier arcs are non-negative
100 * ``.copy()`` method removed: ``copy.copy()`` is preferred way to copy
102 * Copies made previously with ``.copy()`` lacked ``.defined`` field,
104 * All objects are friendly to ``pickle`` libraries
105 * PrintableString has ``allow_asterisk`` and ``allow_ampersand``
107 * ``.hexencode()``, ``.hexdecode()`` and ``.hexdecod()`` methods
108 appeared, working with hexadecimal encoded data
114 * Convenient ``.decod()`` method, that raises if tail is not empty
115 * Control characters (like newlines) of text fields in pprinted output
117 * Ability to allow asterisk and ampersand characters
118 (``allow_asterisk``, ``allow_ampersand`` kwargs) in PrintableString,
119 that unfortunately could be met in X.509 certificates
125 * PEP-396 compatible module's ``__version__``
131 * Do not shadow underlying DecodeError during decoding of optional
138 * Forbid any later GNU GPL version autousage (project's licence now is
140 * Fix ``defines_by_path`` context option usage example
146 * Fix fallbacked ``colored()`` function workability,
147 if no ``termcolor`` is installed
153 * Fix empty ``--oids`` workability
159 * Ability to specify multiple OID mappings for pprinted output
160 (``oids`` keyword argument is renamed to ``oid_maps``)
166 * Minor decode speed improvements
167 * Much faster UTCTime/GeneralizedTime decoders
168 * Stricter UTCTime/GeneralizedTime DER encoding check: trailing zeroes
170 * Valid DER encoding of GeneralizedTime with microseconds: no trailing
177 * ObjectIdentifier has ``ber_encoded`` set to True, if non-normalized
179 * Preserve BER-related attributes during ``copy()``
185 * Added `COMPLI <https://github.com/YuryStrozhevsky/asn1-test-suite>`__
186 ASN.1:2008 test suite. PyDERASN passes it (except for REAL values),
187 but it is more strict sometimes and aimed to be compliant with X.690-201508
188 * Check for arc values normalization in ObjectIdentifier.
189 Forbid non-normalized in DER encoding
195 * ``ctx`` parameter can be safely used in .decode() and won't be muted
196 * PP nametuple contains reference to the ASN1Obj itself
197 * ``colonize_hex`` function useful for pretty printing
198 * Integer values are also pretty printed in hexadecimal form
204 * All errors are inherited from ASN1Error class
205 * NumericString/PrintableString has ``allowable_chars`` property holding
206 all allowed characters
212 * Fix NumericString: space is allowed character
213 * Strict PrintableString sanitizing
219 * Removed ``lenindef``, ``ber_encoded`` attributes from the Choice --
220 they must be taken from underlying value, as Choice does not have its
222 * Do not yield extra EOC PP for Any, having indefinite length encoding
223 and containing autodecoded DEFINED BY value
229 * ``bered`` attribute, meaning if object has BER-specific encoding, is
230 renamed to ``ber_encoded``
231 * ``bered`` attribute is replace with property showing if any of
232 underlying values are BER-encoded. If value has length indefinite
233 encoded explicit tag, value, if value contains BER-related encoding,
234 or if it contains other objects that are ``bered``, then it is ``bered``
240 * Default value is checked also for Sets, not for Sequences only
241 * **Incompatible** change: defaulted values in Sequence/Set are always
242 strictly checked, unless ``allow_default_values`` context option is
243 set. ``strict_default_existence`` option disappeared
244 * Strict Set/Set Of's values ordering check
250 * Additional encoding validness check: explicit tag must contain exactly
251 one object inside. Throw DecodeError otherwise
252 * ``allow_expl_oob`` context and command-line options allow skipping of
259 * DecodeError's decode paths are separated with ``:``, instead of ``.``,
260 because of colliding with dots in OIDs
261 * Ability to print element decode paths with ``--print-decode-path``
262 command line option (and corresponding keyword argument)
263 * Ability to print tree's branch specified with ``--decode-path-only``
269 * Fix possible uncaught TypeError in Py2 with zero bytes inside the value
270 * Fix SequenceOf/SetOf raising BoundsError instead of DecodeError
276 * Fix uncaught UTCTime/GeneralizedTime decode error when dealing with
277 non ASCII-encoded values
283 * Fix long-standing bug with explicitly tagged objects inside the
284 Choice. If Choice had explicitly tagged value, then its ``.tlvlen``
285 reports the size without taking value's explicit tag in advance
286 * Add ``.fulllen`` and ``.fulloffset`` properties for all objects
292 * SEQUENCE's values are printed with field's name. Previously there was
293 the following output::
295 AlgorithmIdentifier SEQUENCE[OBJECT IDENTIFIER 1.3.14.3.2.26, [UNIV 5] ANY 0500 OPTIONAL]
299 AlgorithmIdentifier SEQUENCE[algorithm: OBJECT IDENTIFIER 1.3.14.3.2.26; parameters: [UNIV 5] ANY 0500 OPTIONAL]
300 * Fixed EOC (Unicode character) repr printing issues under Python2
306 BER's EOC is explicitly shown during pprinting. Following notation::
308 15-2 [0,0,1576]-4 . content: [0] EXPLICIT [UNIV 16] ANY
312 15-2∞ [0,0,1576]∞ . content: [0] EXPLICIT [UNIV 16] ANY
314 1587 [1,1, 0] . content: BER EOC
315 1589 [1,1, 0] . content: EXPLICIT BER EOC
321 * BER decoding support
322 * BitString's ''H notation support
323 * ``termcolor`` package is included in the tarball
329 * Ability to set values during Sequence initialization
335 * Fix TagMismatch exception completeness during Choice and Set decoding.
336 Previously we will loose offset and decode_path information about
337 concrete TagMismatched entity
343 * Strict NumericString's value sanitation
344 * Invalid encoding in string types will raise ``DecodeError`` exception,
345 instead of ``Unicode*Error``
346 * Fixed DecodePathDefBy workability with Python 2.x
352 * Fix nasty BitString decoding bug: it could fail when data follows
353 encoded BitString value. There weren't any problems when BitString is
354 at the end of Sequence
360 * Slightly corrected colours, now visible on white background
366 * Fix bug related to DecodeError showing with DecodePathDefBy entities
367 * Respect ``NO_COLOR`` environment variable
373 * :py:func:`pyderasn.decode_path_defby` is replaced with
374 :py:class:`pyderasn.DecodePathDefBy`
375 * Ability to turn colourized terminal output by calling
376 ``pprint(..., with_colours=True)``. You will need
377 `termcolor package <https://pypi.org/project/termcolor/>`__
383 * Fixed invalid offset calculation when dealing with DEFINED BY objects
390 * BIT STRINGs can also be :ref:`DEFINED BY <definedby>`
391 * Decoding process can be governed with optional :ref:`ctx <ctx>`
392 keyword argument to ``decode()`` method
393 * :ref:`defines_by_path <defines_by_path_ctx>` option is now
394 :ref:`decode context <ctx>` option, not a keyword argument
395 * Ability to do ``strict validation``
396 of defaulted values met in sequence, raising an exception
402 Ability to skip specified number of bytes (``--skip``) in command line
409 * Generic decoder's schema and pretty printer
410 (:py:func:`pyderasn.generic_decoder`) can be used in libraries
411 * Ability to specify :ref:`defines_by_path <defines_by_path_ctx>`
412 during command line invocation
418 Ability to automatically decode :ref:`DEFINED BY <definedby>` fields
425 Removed ``__lt__``/``__eq__`` from base class, as pylint likes it.
431 Full rich comparison operators added.
438 Trivial README addition.
