8 * Proper strict alphabet validation of VisibleString
9 * VisibleString and IA5String also have ``allowable_chars`` property
10 * Fixed TeletexString, T61String use ``iso-8859-1`` encoding (instead of
11 ``ascii``), because they are 8-bit encodings
17 * Also print full TLVlen in ASN.1 browser
24 * Fix DEFINED BY pprinting when invoking as __main__ module
25 * Integer has ``tohex()`` for getting hexadecimal representation of its value
26 * ``hexdump()`` (``hexdump -C`` like output) and ``ascii_visualize()``
27 (visualize ASCII printable characters, like in ``hexdump -C``) pretty
28 printing functions appeared
29 * Experimental ASN.1 interactive terminal browser (``--browse`` and
31 You will need `urwid package <http://urwid.org/>`__ to use it
38 * SEQUENCE/SET fully performs default value existence validation in
39 evgen mode, by the cost of DEFAULTed value full decoding. That should
40 not be the problem, as DEFAULTs are relatively small in practice. Now
41 evgen mode has the same DER validation strictness as an ordinary one
48 * Restored workability of some command line options
49 * 2-pass DER encoding mode with very little memory footprint
62 * Fixed invalid behaviour where SET OF allowed multiple objects with the
63 same tag to be successfully decoded
64 * Fixed possibly invalid SET DER encoding where objects were not sorted
65 by tag, but by encoded representation
66 * ``Any`` does not allow empty data value now. Now it checks if it has
68 * ``SetOf`` is not treated as ready, if no value was set and minimum
69 bounds are greater than zero
70 * ``Any`` allows an ordinary ``Obj`` storing, without its forceful
71 encoded representation storage. That is required for CER encoding
72 mode, where we do not know in advance what encoding will be used
73 * ``ObjectIdentifier`` stores values as C unsigned long integer,
74 forbidding storage of huge integers, that must not be a problem in
76 * Initial support for so called ``evgen_mode``: event generation mode,
77 where no in-memory objects storing happens, giving ability to process
78 ASN.1 data without fully parsing it first. ``python -m pyderasn`` has
79 ``--evgen`` mode switcher
80 * Useful ``agg_octet_string`` that is able to streamingly decode string
81 from events of ``evgen_mode``, allowing strings retrieving without
82 copying them to memory first
83 * Initial experimental CER encoding mode, allowing streaming encoding of
84 the data directly to some writeable object
85 * Ability to use mmap-ed memoryviews to skip files loading to memory
86 * Ability to use memoryview as an input for \*Strings. If they are
87 mmap-ed, then you can encode any quantities of data streamingly
88 without copying to memory
94 * Fixed workability under Python 3.5. Previously only 2.7 and 3.6
101 * Python ``int()``'s accepts even more various non-decimal characters
102 than expected. Make validation fully strict in UTCTime and
103 GeneralizedTime, without relying on ``int()``
109 * UTCTime and GeneralizedTime allowed values to have plus sign in them,
110 passing int() check successfully. Prohibit that incorrect behaviour
111 * UTCTime and GeneralizedTime BER decoding support
112 * Faster UTCTime and GeneralizedTime decoding, and slightly better
114 * Workability under Cython
115 * Explicitly Check that all ObjectIdentifier arcs are non-negative
121 * ``.copy()`` method removed: ``copy.copy()`` is preferred way to copy
123 * Copies made previously with ``.copy()`` lacked ``.defined`` field,
125 * All objects are friendly to ``pickle`` libraries
126 * PrintableString has ``allow_asterisk`` and ``allow_ampersand``
128 * ``.hexencode()``, ``.hexdecode()`` and ``.hexdecod()`` methods
129 appeared, working with hexadecimal encoded data
135 * Convenient ``.decod()`` method, that raises if tail is not empty
136 * Control characters (like newlines) of text fields in pprinted output
138 * Ability to allow asterisk and ampersand characters
139 (``allow_asterisk``, ``allow_ampersand`` kwargs) in PrintableString,
140 that unfortunately could be met in X.509 certificates
146 * PEP-396 compatible module's ``__version__``
152 * Do not shadow underlying DecodeError during decoding of optional
159 * Forbid any later GNU GPL version autousage (project's licence now is
161 * Fix ``defines_by_path`` context option usage example
167 * Fix fallbacked ``colored()`` function workability,
168 if no ``termcolor`` is installed
174 * Fix empty ``--oids`` workability
180 * Ability to specify multiple OID mappings for pprinted output
181 (``oids`` keyword argument is renamed to ``oid_maps``)
187 * Minor decode speed improvements
188 * Much faster UTCTime/GeneralizedTime decoders
189 * Stricter UTCTime/GeneralizedTime DER encoding check: trailing zeroes
191 * Valid DER encoding of GeneralizedTime with microseconds: no trailing
198 * ObjectIdentifier has ``ber_encoded`` set to True, if non-normalized
200 * Preserve BER-related attributes during ``copy()``
206 * Added `COMPLI <https://github.com/YuryStrozhevsky/asn1-test-suite>`__
207 ASN.1:2008 test suite. PyDERASN passes it (except for REAL values),
208 but it is more strict sometimes and aimed to be compliant with X.690-201508
209 * Check for arc values normalization in ObjectIdentifier.
210 Forbid non-normalized in DER encoding
216 * ``ctx`` parameter can be safely used in .decode() and won't be muted
217 * PP nametuple contains reference to the ASN1Obj itself
218 * ``colonize_hex`` function useful for pretty printing
219 * Integer values are also pretty printed in hexadecimal form
225 * All errors are inherited from ASN1Error class
226 * NumericString/PrintableString has ``allowable_chars`` property holding
227 all allowed characters
233 * Fix NumericString: space is allowed character
234 * Strict PrintableString sanitizing
240 * Removed ``lenindef``, ``ber_encoded`` attributes from the Choice --
241 they must be taken from underlying value, as Choice does not have its
243 * Do not yield extra EOC PP for Any, having indefinite length encoding
244 and containing autodecoded DEFINED BY value
250 * ``bered`` attribute, meaning if object has BER-specific encoding, is
251 renamed to ``ber_encoded``
252 * ``bered`` attribute is replace with property showing if any of
253 underlying values are BER-encoded. If value has length indefinite
254 encoded explicit tag, value, if value contains BER-related encoding,
255 or if it contains other objects that are ``bered``, then it is ``bered``
261 * Default value is checked also for Sets, not for Sequences only
262 * **Incompatible** change: defaulted values in Sequence/Set are always
263 strictly checked, unless ``allow_default_values`` context option is
264 set. ``strict_default_existence`` option disappeared
265 * Strict Set/Set Of's values ordering check
271 * Additional encoding validness check: explicit tag must contain exactly
272 one object inside. Throw DecodeError otherwise
273 * ``allow_expl_oob`` context and command-line options allow skipping of
280 * DecodeError's decode paths are separated with ``:``, instead of ``.``,
281 because of colliding with dots in OIDs
282 * Ability to print element decode paths with ``--print-decode-path``
283 command line option (and corresponding keyword argument)
284 * Ability to print tree's branch specified with ``--decode-path-only``
290 * Fix possible uncaught TypeError in Py2 with zero bytes inside the value
291 * Fix SequenceOf/SetOf raising BoundsError instead of DecodeError
297 * Fix uncaught UTCTime/GeneralizedTime decode error when dealing with
298 non ASCII-encoded values
304 * Fix long-standing bug with explicitly tagged objects inside the
305 Choice. If Choice had explicitly tagged value, then its ``.tlvlen``
306 reports the size without taking value's explicit tag in advance
307 * Add ``.fulllen`` and ``.fulloffset`` properties for all objects
313 * SEQUENCE's values are printed with field's name. Previously there was
314 the following output::
316 AlgorithmIdentifier SEQUENCE[OBJECT IDENTIFIER 1.3.14.3.2.26, [UNIV 5] ANY 0500 OPTIONAL]
320 AlgorithmIdentifier SEQUENCE[algorithm: OBJECT IDENTIFIER 1.3.14.3.2.26; parameters: [UNIV 5] ANY 0500 OPTIONAL]
321 * Fixed EOC (Unicode character) repr printing issues under Python2
327 BER's EOC is explicitly shown during pprinting. Following notation::
329 15-2 [0,0,1576]-4 . content: [0] EXPLICIT [UNIV 16] ANY
333 15-2∞ [0,0,1576]∞ . content: [0] EXPLICIT [UNIV 16] ANY
335 1587 [1,1, 0] . content: BER EOC
336 1589 [1,1, 0] . content: EXPLICIT BER EOC
342 * BER decoding support
343 * BitString's ''H notation support
344 * ``termcolor`` package is included in the tarball
350 * Ability to set values during Sequence initialization
356 * Fix TagMismatch exception completeness during Choice and Set decoding.
357 Previously we will loose offset and decode_path information about
358 concrete TagMismatched entity
364 * Strict NumericString's value sanitation
365 * Invalid encoding in string types will raise ``DecodeError`` exception,
366 instead of ``Unicode*Error``
367 * Fixed DecodePathDefBy workability with Python 2.x
373 * Fix nasty BitString decoding bug: it could fail when data follows
374 encoded BitString value. There weren't any problems when BitString is
375 at the end of Sequence
381 * Slightly corrected colours, now visible on white background
387 * Fix bug related to DecodeError showing with DecodePathDefBy entities
388 * Respect ``NO_COLOR`` environment variable
394 * :py:func:`pyderasn.decode_path_defby` is replaced with
395 :py:class:`pyderasn.DecodePathDefBy`
396 * Ability to turn colourized terminal output by calling
397 ``pprint(..., with_colours=True)``. You will need
398 `termcolor package <https://pypi.org/project/termcolor/>`__
404 * Fixed invalid offset calculation when dealing with DEFINED BY objects
411 * BIT STRINGs can also be :ref:`DEFINED BY <definedby>`
412 * Decoding process can be governed with optional :ref:`ctx <ctx>`
413 keyword argument to ``decode()`` method
414 * :ref:`defines_by_path <defines_by_path_ctx>` option is now
415 :ref:`decode context <ctx>` option, not a keyword argument
416 * Ability to do ``strict validation``
417 of defaulted values met in sequence, raising an exception
423 Ability to skip specified number of bytes (``--skip``) in command line
430 * Generic decoder's schema and pretty printer
431 (:py:func:`pyderasn.generic_decoder`) can be used in libraries
432 * Ability to specify :ref:`defines_by_path <defines_by_path_ctx>`
433 during command line invocation
439 Ability to automatically decode :ref:`DEFINED BY <definedby>` fields
446 Removed ``__lt__``/``__eq__`` from base class, as pylint likes it.
452 Full rich comparison operators added.
459 Trivial README addition.
