...When the length of the data is known, there is no risk of misinterpreting it on the basis of spaces or text delimiters. The Distinguished Encoding Rules, or DER, of the ASN.1 standard follows this approach but includes numerous constraints and, more importantly, demands that data fields to be described using binary metadata rather than text. The Secure Protocol Format, or SPF, was created as a simplified version of DER. In addition to delimiting data by length, it also affords programmers the ability to use text for describing data, just like tags are used in HTML and XML. ...

ASN.1 types and codecs (BER, CER, DER) implementation in Python programming language. A collection of various ASN.1-based protocols data structures is supplied in a dedicated Python package. Project moved to GitHub: https://github.com/etingof/pyasn1

A simple Java ASN BER decoder and profiler A tool for easy manipulation of BER encoded files. An "awk" for ASN.1 BER (for Unix people) or maybe a "notepad" for ASN.1 BER (for Windows people). Jberd (Java BER decoder) is a lightweight BER decoder and associated tools for interpreting and processing BER encoded ASN.1 files. The following facilities are provided: • JBerd Profiler.

BinaryNotes is the Open Source ASN.1 (Abstract Syntax Notation One) framework for Java and .NET based on annotations/attributes. The framework has the flexible ASN.1 compiler, the runtime library that supports BER, DER and PER, and the Message Queues

CoDec is a Java package for encoding and decoding ASN.1 data structures. CoDec supports the Basic Encoding Rules (BER) as well as the Distinguished Encoding Rules (DER) and provides a library with data structures for many cryptographic standards.

IvmaiAsn ASN1/ECN/XDR Tools. A collection of the ASN.1/ECN parser, XDR-to-ASN.1 converter and pretty-printer scripts for ASN.1/ECN specifications. Contains also a formal definition of the ASN.1 built-in types, ECN encoding classes and XDR encodings.

Meta-Messager: A project that aims to develop a Semantic Web based framework for semantic annotation of B2B message schemas (e.g. XML, EDIFACT, ASN.1) and translation of B2B messages to and from business ontologies.

Complete ASN.1 libraray supporting the encodings BER/DER/CER (PER is planned for the future). The use of features of the .NET 2.0 framework, e.g. generics, shall ease the creation of other libraries and applications.

Pure-Java cryptographic calculator, featuring basic arithmetic operators, cryptographic operations, multiple key file formats and edition of ASN.1 object files.

A simple ASN.1 toolkit and libraries to add ASN.1 serialization to Java classes. Serialization schemes are targetted at XML integration.

This project aims at providing simple and powerful tools and programming interface in C++ with fast and compact binary code to encode/decode data to/from ASN-1 and GDMO.
