-PyDERASN -- ASN.1 DER/BER library for Python
+PyDERASN -- strict and fast ASN.1 DER/CER/BER library for Python
I'm going to build my own ASN.1 library with slots and blobs!
(C) PyDERASN's author
-* BER/CER/DER decoding, DER encoding
+* BER/CER/DER decoding, strict DER validation, DER/CER encoding
* Basic ASN.1 data types (X.208): BOOLEAN, INTEGER, BIT STRING, OCTET
STRING, NULL, OBJECT IDENTIFIER, ENUMERATED, all strings, UTCTime,
GeneralizedTime, CHOICE, ANY, SEQUENCE (OF), SET (OF)
* Size constraints checking
* Working with sequences as high level data objects with ability to
(un)marshall them
-* Python 2.7/3.5/3.6 compatibility
+* Aimed to be complaint with X.690-201508
+* Streaming decoding and encoding capabilities, allowing working with
+ very small memory footprint
+* Python 3.5+ compatibility
* Automatic decoding of DEFINED BY fields
* Ability to know exact decoded objects offset and lengths in the binary
+* Ability to allow BER-encoded data with knowing if any of specified
+ field has either DER or BER encoding (or possibly indefinite-length
+ encoding)
+* Ability to use mmap-ed files, memoryviews, iterators, 2-pass DER
+ encoding mode and CER encoder dealing with the writer, giving ability
+ to create huge ASN.1 encoded files with very little memory footprint
+* Ability to decode files in event generation mode, without the need to
+ keep all the data and decoded structures in the memory
+* __slots__, copy.copy() friendliness
+* Workability with pickle
+* Cython compatibility
+* Descriptive errors, with decode paths
* Pretty printer and command-line decoder, that could conveniently
replace utilities like either dumpasn1 or openssl asn1parse
-* __slots__ friendliness
