Introduction

ASN1DECODER (ASN.1 to text decoder) is a statically-linked command-line application that is used to translate binary data encoded using various ASN.1 encoding rules (BER/CER/DER and PER/UPER) to text-based XML or JSON output formats.

Release Notes

Users are encouraged to consult the documentation in the doc subdirectory for information regarding the transformation of binary input files into output textual formats.

Up-to-date change log information for future releases will be made available on our website.

Documentation

Documentation for this release is provided in the doc subdirectory of the installation.

Windows Installation

The steps to install ASN1DECODER on a Windows system are as follows:

1. Download the ASN1DECODER package distribution file.
2. ASN1DECODER for Windows is packaged in a self-extracting executable file format. To install, all that should be necessary is to double-click this file after downloading and then following the setup wizard instructions.

An osyslic.txt license is necessary to enable the product to run. This should have been sent as an attachment in an E-mail message or should be available on the user's product download web page. Copy this file into the 'bin' subdirectory of the asn1dec installation.

ASN1DECODER should now be operational. Refer to the ASN1DECODER User's Guide document in the doc subdirectory for instructions on how to run the program.

Contents of the Release

The following subdirectories contain the following files (note: <installdir> refers to the installation directory that was specified during the installation process):

<installdir>\bin\asn1dec.exe

The asn1decoder command-line program executable file.

<installdir>\doc

This directory contains the ASN1DECODER User's Guide file asn1dec.pdf file.

<installdir>\asn1specs

This directory contains a collection of common ASN.1 specification files from existing standards that have been used with the tool.

<installdir>\sample

This directory contains sample programs containing encoded BER/DER message files (these files have a '.dat' or '.bin' extension) and corresponding ASN.1 schema files (these have extension '.asn'). ASN1DECODER can be used to translate these files to text formats. A perl script (asn1dec.pl) is provided to test the translation of all files to text formats.

<installdir>\sample_per

This directory contains sample data containing PER message files and corresponding ASN.1 schema files. ASN1DECODER can be used to translate these files to XML. A Perl script, asn1dec.pl, is provided for this purpose.
