1 PyDERASN -- strict and fast ASN.1 DER/BER library for Python
3 I'm going to build my own ASN.1 library with slots and blobs!
6 * BER/CER/DER decoding, DER encoding
7 * Basic ASN.1 data types (X.208): BOOLEAN, INTEGER, BIT STRING, OCTET
8 STRING, NULL, OBJECT IDENTIFIER, ENUMERATED, all strings, UTCTime,
9 GeneralizedTime, CHOICE, ANY, SEQUENCE (OF), SET (OF)
10 * Size constraints checking
11 * Working with sequences as high level data objects with ability to
13 * Python 2.7/3.5/3.6 compatibility
14 * Automatic decoding of DEFINED BY fields
15 * Ability to know exact decoded objects offset and lengths in the binary
16 * Pretty printer and command-line decoder, that could conveniently
17 replace utilities like either dumpasn1 or openssl asn1parse
18 * __slots__, copy.copy(), pickle friendliness
20 pyderasn is free software: see the file COPYING.LESSER for copying conditions.
