This file contains release notes on the ASN1DECODER 3.1 release.
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.
New features appearing in the 3.1 release of ASN1DECODER include the following:
- General stability and bug fixes.
Users are encouraged to consult the documentation in the
docsubdirectory 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 for this release is provided in the
docsubdirectory of the installation.
ASN1DECODER for UNIX/Linux is packaged as a gzipped .tar archive file. This distribution file can be unpacked in any directory on the target system by executing the following commands:
- gunzip asn1dec<version><platform>.tar.gz
- tar xf asn1dec<version><platform>.tar
- rm asn1dec<version><platform>.tar
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 asn2txt 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.
The following subdirectories contain the following files (note: <installdir> refers to the installation directory that was specified during the installation process):
- The asn2txt command-line program executable file.
- This directory contains the ASN1DECODER User's Guide file asn1dec.pdf file.
- This directory contains a collection of common ASN.1 specification files from existing standards that have been used with the tool.
- 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.
- 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.
Report problems you encounter by sending E-mail to email@example.com. The preferred format of example programs is the same as the sample programs. Please provide a message file and an ASN.1 syntax file and also indicate where the problem occurs.
If you have any further questions or comments on what you would like to see in the product or what is difficult to use or understand, please communicate them to us. Your feedback is important to us.
