The OSS® ASN.1 Tools for C is a complete development toolkit for rapidly building applications using ASN.1. This product features a powerful ASN.1:2015 capable compiler, a runtime library with ASN.1 BER, CER, DER, PER, OER, COER, XER, CXER and EXER encoder/decoder engines, and a rich collection of utilities to simplify and speed your development. The OSS ASN.1 Tools for C fully support 4G (LTE: RRC, S1AP, and X2AP protocols).
The compiler takes ASN.1 specifications as input, and generates C language data structures plus control tables for encoding and decoding. The OSS compiler offers extensive diagnostic capabilities to minimize your development time and effort.
A set of runtime libraries provides ASN.1 encoding and decoding functions and valuable auxiliary functions to operate on application messages. The OSS runtime libraries have been ported to 500+ platforms, including many embedded platforms.
Support for JSON ER allows serializing ASN.1 data to the popular JSON format and converting between JSON messages and ASN.1 binary messages.
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.
If you need high speed encoding/decoding and the smallest possible memory footprint, look no further. Simply put, the OSS ASN.1 Tools for C are the most optimized ASN.1 tools you will ever find.
