Tools

​Tools for ASN.1 are available on almost all operating systems. They generate code for popular programming languages such as Java, C and C++, as well as older ones including COBOL. As an example of ASN.1's universality, there are tools that have been ported to over 250 different computing platforms.
There are a lot of well-tested ASN.1 tools that have been used for a long time. Using such tools, there are less likely to be costly delays in bringing new products to market or, even worse, recalling products based on new code that hasn't been sufficiently tested for flaws.

ASN.1 compiler and runtime support

  • OSS ASN.1 Tools (OSS Nokalva, Inc.)
    Highly optimized & reliable ASN.1 tools for both ASN.1:1990 and ASN.1:1994/1997/2002/2008/2015 (full support), with BER, DER, CER, OER, PER, UPER, CPER, CUPER, XER/CXER/E-XER(XML), and JSON runtimes for C, C++, C# and Java. More than low-level ASN.1 support.
  • Asn1Compiler (uniGone)
    ASN.1:2002 compiler, BER, DER, PER and EXTENDED-XER (E-XER) encoding; generates Java and C#
 
  • MARBEN ASN.1 Tools (Marben Products)
    ASN.1:2008 compiler; time and memory optimized BER, DER, PER, UPER, XER, CXER and E-XER runtimes for C, C++ or Java. XML/XSD features.
  • P1Sec/pycrate
    A Python library to ease the development of encoders and decoders for various protocols and file formats; contains ASN.1 and CSN.1 compilers.
  • ASN1SCC
    An open source ASN.1 compiler targeting real-time, embedded platforms, Has C and Spark/Ada backends for uPER, XER, as well as support for legacy binary encodings
