  57 ## Features
  58
  59 In addition to an ASN.1 BER/DER decoder and DER serializer, the project
  60 includes
  61 a bunch of ASN.1 structures for use with various common cryptography

  98 ## Why Another Python ASN.1 Library?
  99
 100 Python has long had the [pyasn1] and
 101 [pyasn1_modules] available for
 102 parsing and serializing ASN.1 structures. While the project does include a
 103 comprehensive set of tools for parsing and serializing, the performance of
 104 the
 105 library can be very poor, especially when dealing with bit fields and
 106 parsing
 107 large structures such as CRLs.
 108
 109 After spending extensive time using *pyasn1*, the following issues were
 110 identified:
 111
 112  1. Poor performance
 113  2. Verbose, non-pythonic API
 114  3. Out-dated and incomplete definitions in *pyasn1-modules*
 115  4. No simple way to map data to native Python data structures
 116  5. No mechanism for overridden universal ASN.1 types
 117
 118 The *pyasn1* API is largely method driven, and uses extensive configuration
 119 objects and lowerCamelCase names. There were no consistent options for
 120 converting types of native Python data structures. Since the project
 121 supports
 122 out-dated versions of Python, many newer language features are unavailable
 123 for use.
 124
 125 Time was spent trying to profile issues with the performance, however the
 126 architecture made it hard to pin down the primary source of the poor
 127 performance. Attempts were made to improve performance by utilizing
 128 unreleased
 129 patches and delaying parsing using the `Any` type. Even with such changes,
 130 the
 131 performance was still unacceptably slow.
