ASN.1 Tools for C++ — Overview

ASN.1/CPP

The OSS® ASN.1 Tools for C++ is a development tool for building true C++ applications using ASN.1. This product provides the application programmer with a series of C++ classes that allow common programming operations according to the well-known principles of object-oriented programming.

High Performance
Encoder/Decoder

This popular product features a powerful compiler, a runtime library with ASN.1 BER, CER, DER, PER/UPER, CPER/CUPER, OER, COER, XER, CXER, E-XER, JSON, and AVN encoder/decoder engines, and a number of utilities to simplify and speed your development.

Support for
Partial Decoding

Our ASN.1 products support LTE Advanced Pro including NB-IoT, C-V2X and LTE-M. OSS products support the 3GPP 5G specifications.

The compiler takes ASN.1 specifications as input, and generates C++ classes as well as control tables for encoding/decoding. In addition to core functionalities, the OSS compiler offers diagnostic capabilities that minimize your development time and effort.

The OSS toolkit includes a set of runtime libraries designed to implement ASN.1 encoding and decoding functions and perform auxiliary operations on application messages.

Support for JSON Encoding Rules allows serializing ASN.1 data to the popular JSON format and converting between JSON messages and ASN.1 binary messages.

Support for
JSON, OER,
and CPER/CUPER

Support for OER allows working with ASN.1 binary messages that can be encoded/decoded significantly faster than BER and PER messages, while being only slightly less compact than PER messages.

Support for E-XER allows generation of XML compatible with output from XML Schema tools.

ASN.1 Tools for C++ features
  • Unparalleled speed of encoders and decoders
  • Backward compatibility guaranteed
  • ASN.1 Studio, an intuitive IDE for ASN.1 specification editing and message analysis
  • Support for partial decoding
  • Large (4096 bit) INTEGERs (for cryptographic applications)
  • Unlimited value size
  • Type representations which reflect the semantics of ASN.1 (4 byte UniversalStrings, Time classes)
  • Encoding of extensible types (unknown extensions)
  • Rich set of C++ representation classes for ASN.1 types
  • Automatic decoding for any kind of constraint
  • No implementation restrictions; never rewrite your ASN.1 to accommodate encoding limitations
  • Defer decoding of any individual field or type
  • File and socket support
  • Concatenated PDU support
  • Contents constraints (full support)
  • Generate XML stylesheet or DTD for each PDU
