9 * Fix DEFINED BY pprinting when invoking as __main__ module
10 * Integer has ``tohex()`` for getting hexadecimal representation of its value
11 * ``hexdump()`` (``hexdump -C`` like output) and ``ascii_visualize()``
12 (visualize ASCII printable characters, like in ``hexdump -C``) pretty
13 printing functions appeared
14 * Experimental ASN.1 interactive terminal browser (``--browse`` and
16 You will need `urwid package <http://urwid.org/>`__ to use it
23 * SEQUENCE/SET fully performs default value existence validation in
24 evgen mode, by the cost of DEFAULTed value full decoding. That should
25 not be the problem, as DEFAULTs are relatively small in practice. Now
26 evgen mode has the same DER validation strictness as an ordinary one
33 * Restored workability of some command line options
34 * 2-pass DER encoding mode with very little memory footprint
47 * Fixed invalid behaviour where SET OF allowed multiple objects with the
48 same tag to be successfully decoded
49 * Fixed possibly invalid SET DER encoding where objects were not sorted
50 by tag, but by encoded representation
51 * ``Any`` does not allow empty data value now. Now it checks if it has
53 * ``SetOf`` is not treated as ready, if no value was set and minimum
54 bounds are greater than zero
55 * ``Any`` allows an ordinary ``Obj`` storing, without its forceful
56 encoded representation storage. That is required for CER encoding
57 mode, where we do not know in advance what encoding will be used
58 * ``ObjectIdentifier`` stores values as C unsigned long integer,
59 forbidding storage of huge integers, that must not be a problem in
61 * Initial support for so called ``evgen_mode``: event generation mode,
62 where no in-memory objects storing happens, giving ability to process
63 ASN.1 data without fully parsing it first. ``python -m pyderasn`` has
64 ``--evgen`` mode switcher
65 * Useful ``agg_octet_string`` that is able to streamingly decode string
66 from events of ``evgen_mode``, allowing strings retrieving without
67 copying them to memory first
68 * Initial experimental CER encoding mode, allowing streaming encoding of
69 the data directly to some writeable object
70 * Ability to use mmap-ed memoryviews to skip files loading to memory
71 * Ability to use memoryview as an input for \*Strings. If they are
72 mmap-ed, then you can encode any quantities of data streamingly
73 without copying to memory
79 * Fixed workability under Python 3.5. Previously only 2.7 and 3.6
86 * Python ``int()``'s accepts even more various non-decimal characters
87 than expected. Make validation fully strict in UTCTime and
88 GeneralizedTime, without relying on ``int()``
94 * UTCTime and GeneralizedTime allowed values to have plus sign in them,
95 passing int() check successfully. Prohibit that incorrect behaviour
96 * UTCTime and GeneralizedTime BER decoding support
97 * Faster UTCTime and GeneralizedTime decoding, and slightly better
99 * Workability under Cython
100 * Explicitly Check that all ObjectIdentifier arcs are non-negative
106 * ``.copy()`` method removed: ``copy.copy()`` is preferred way to copy
108 * Copies made previously with ``.copy()`` lacked ``.defined`` field,
110 * All objects are friendly to ``pickle`` libraries
111 * PrintableString has ``allow_asterisk`` and ``allow_ampersand``
113 * ``.hexencode()``, ``.hexdecode()`` and ``.hexdecod()`` methods
114 appeared, working with hexadecimal encoded data
120 * Convenient ``.decod()`` method, that raises if tail is not empty
121 * Control characters (like newlines) of text fields in pprinted output
123 * Ability to allow asterisk and ampersand characters
124 (``allow_asterisk``, ``allow_ampersand`` kwargs) in PrintableString,
125 that unfortunately could be met in X.509 certificates
131 * PEP-396 compatible module's ``__version__``
137 * Do not shadow underlying DecodeError during decoding of optional
144 * Forbid any later GNU GPL version autousage (project's licence now is
146 * Fix ``defines_by_path`` context option usage example
152 * Fix fallbacked ``colored()`` function workability,
153 if no ``termcolor`` is installed
159 * Fix empty ``--oids`` workability
165 * Ability to specify multiple OID mappings for pprinted output
166 (``oids`` keyword argument is renamed to ``oid_maps``)
172 * Minor decode speed improvements
173 * Much faster UTCTime/GeneralizedTime decoders
174 * Stricter UTCTime/GeneralizedTime DER encoding check: trailing zeroes
176 * Valid DER encoding of GeneralizedTime with microseconds: no trailing
183 * ObjectIdentifier has ``ber_encoded`` set to True, if non-normalized
185 * Preserve BER-related attributes during ``copy()``
191 * Added `COMPLI <https://github.com/YuryStrozhevsky/asn1-test-suite>`__
192 ASN.1:2008 test suite. PyDERASN passes it (except for REAL values),
193 but it is more strict sometimes and aimed to be compliant with X.690-201508
194 * Check for arc values normalization in ObjectIdentifier.
195 Forbid non-normalized in DER encoding
201 * ``ctx`` parameter can be safely used in .decode() and won't be muted
202 * PP nametuple contains reference to the ASN1Obj itself
203 * ``colonize_hex`` function useful for pretty printing
204 * Integer values are also pretty printed in hexadecimal form
210 * All errors are inherited from ASN1Error class
211 * NumericString/PrintableString has ``allowable_chars`` property holding
212 all allowed characters
218 * Fix NumericString: space is allowed character
219 * Strict PrintableString sanitizing
225 * Removed ``lenindef``, ``ber_encoded`` attributes from the Choice --
226 they must be taken from underlying value, as Choice does not have its
228 * Do not yield extra EOC PP for Any, having indefinite length encoding
229 and containing autodecoded DEFINED BY value
235 * ``bered`` attribute, meaning if object has BER-specific encoding, is
236 renamed to ``ber_encoded``
237 * ``bered`` attribute is replace with property showing if any of
238 underlying values are BER-encoded. If value has length indefinite
239 encoded explicit tag, value, if value contains BER-related encoding,
240 or if it contains other objects that are ``bered``, then it is ``bered``
246 * Default value is checked also for Sets, not for Sequences only
247 * **Incompatible** change: defaulted values in Sequence/Set are always
248 strictly checked, unless ``allow_default_values`` context option is
249 set. ``strict_default_existence`` option disappeared
250 * Strict Set/Set Of's values ordering check
256 * Additional encoding validness check: explicit tag must contain exactly
257 one object inside. Throw DecodeError otherwise
258 * ``allow_expl_oob`` context and command-line options allow skipping of
265 * DecodeError's decode paths are separated with ``:``, instead of ``.``,
266 because of colliding with dots in OIDs
267 * Ability to print element decode paths with ``--print-decode-path``
268 command line option (and corresponding keyword argument)
269 * Ability to print tree's branch specified with ``--decode-path-only``
275 * Fix possible uncaught TypeError in Py2 with zero bytes inside the value
276 * Fix SequenceOf/SetOf raising BoundsError instead of DecodeError
282 * Fix uncaught UTCTime/GeneralizedTime decode error when dealing with
283 non ASCII-encoded values
289 * Fix long-standing bug with explicitly tagged objects inside the
290 Choice. If Choice had explicitly tagged value, then its ``.tlvlen``
291 reports the size without taking value's explicit tag in advance
292 * Add ``.fulllen`` and ``.fulloffset`` properties for all objects
298 * SEQUENCE's values are printed with field's name. Previously there was
299 the following output::
301 AlgorithmIdentifier SEQUENCE[OBJECT IDENTIFIER 1.3.14.3.2.26, [UNIV 5] ANY 0500 OPTIONAL]
305 AlgorithmIdentifier SEQUENCE[algorithm: OBJECT IDENTIFIER 1.3.14.3.2.26; parameters: [UNIV 5] ANY 0500 OPTIONAL]
306 * Fixed EOC (Unicode character) repr printing issues under Python2
312 BER's EOC is explicitly shown during pprinting. Following notation::
314 15-2 [0,0,1576]-4 . content: [0] EXPLICIT [UNIV 16] ANY
318 15-2∞ [0,0,1576]∞ . content: [0] EXPLICIT [UNIV 16] ANY
320 1587 [1,1, 0] . content: BER EOC
321 1589 [1,1, 0] . content: EXPLICIT BER EOC
327 * BER decoding support
328 * BitString's ''H notation support
329 * ``termcolor`` package is included in the tarball
335 * Ability to set values during Sequence initialization
341 * Fix TagMismatch exception completeness during Choice and Set decoding.
342 Previously we will loose offset and decode_path information about
343 concrete TagMismatched entity
349 * Strict NumericString's value sanitation
350 * Invalid encoding in string types will raise ``DecodeError`` exception,
351 instead of ``Unicode*Error``
352 * Fixed DecodePathDefBy workability with Python 2.x
358 * Fix nasty BitString decoding bug: it could fail when data follows
359 encoded BitString value. There weren't any problems when BitString is
360 at the end of Sequence
366 * Slightly corrected colours, now visible on white background
372 * Fix bug related to DecodeError showing with DecodePathDefBy entities
373 * Respect ``NO_COLOR`` environment variable
379 * :py:func:`pyderasn.decode_path_defby` is replaced with
380 :py:class:`pyderasn.DecodePathDefBy`
381 * Ability to turn colourized terminal output by calling
382 ``pprint(..., with_colours=True)``. You will need
383 `termcolor package <https://pypi.org/project/termcolor/>`__
389 * Fixed invalid offset calculation when dealing with DEFINED BY objects
396 * BIT STRINGs can also be :ref:`DEFINED BY <definedby>`
397 * Decoding process can be governed with optional :ref:`ctx <ctx>`
398 keyword argument to ``decode()`` method
399 * :ref:`defines_by_path <defines_by_path_ctx>` option is now
400 :ref:`decode context <ctx>` option, not a keyword argument
401 * Ability to do ``strict validation``
402 of defaulted values met in sequence, raising an exception
408 Ability to skip specified number of bytes (``--skip``) in command line
415 * Generic decoder's schema and pretty printer
416 (:py:func:`pyderasn.generic_decoder`) can be used in libraries
417 * Ability to specify :ref:`defines_by_path <defines_by_path_ctx>`
418 during command line invocation
424 Ability to automatically decode :ref:`DEFINED BY <definedby>` fields
431 Removed ``__lt__``/``__eq__`` from base class, as pylint likes it.
437 Full rich comparison operators added.
444 Trivial README addition.
