Go to github.com/vlm/asn1c for the latest version.
This ASN.1 compiler turns ASN.1 specifications into C code. The asn1c is shipped together with conformant BER/DER/XER/PER codecs. The X.509, GSM TAP3, MEGACO, RRC and LDAP encoding and decoding examples are part of the source code distribution.
NOTE: THE asn1c PROJECT HAS LARGELY MOVED TO GITHUB: http://github.com/vlm/asn1c
Python modules that wrap Lev Walkin's asn1c code.
ASN.1 notation is translated to C-code and this code is built into python module that can der-encode and -decode structures from ASN.1 description.
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
nwWimaxAsnCp library is implementation of WiMAX ASN Control Protocol stack as per WiMAX forum specification release 1.0.
WiMAX Base Stations and ASN Gateways make use the protocol for control plane signaling on R4, R6 and R8 interfaces.

The project is supposed to be a helper tool for administrators in providing a centralized place to track your routes, view them on google maps, show abuse info, dns tracking, asn, blocklists etc'
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.
Release 1 of BroadBit Test Tool (BTT) offers the power and efficiency of TTCN testing; all software testing engineers can add this platform independent tool it into their toolbox.
Training support is available through training@broadbit.com.
NepenthesFE is a front-end to the Nepenthes Honeypot. It provides visualization of data captured from the honeypot. It also provides additional details like VirusTotal scans, Strings, Packer information, ASN details, Geo-Location, ObjDump.
LTE ASN.1 Message Editor (lameditor) is a open source tool for editing long term evolution (LTE) RRC messages. It can be used as a start for commercial applications and ideal for test purposes.
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.
JAC (Java Asn1 Compiler) is a tool for you if you want to (1)parse your asn1 file (2)create .java classes and (3)encode/decode instances of your classes. Just forget all asn1 byte streams, and take the advantage of OOP! BER, CER and DER are all supported
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.
openASN.1 is an Open Source Java toolkit for the Abstract Syntax Notation One (ASN.1) which consists of a compiler and codec with a low footprint runtime library.
"mASN1" - mini ASN.1 framework is a light ASN.1 framework written in C# for .NET
framework. It can be used for creating classes that model ASN.1 types and
are capable of encoding/decoding themselves to BER/DER codes. PER support is planned.
Encode/Decode library to/from Basic Encoding Rules (BER) of ASN.1 written in Visual Basic .Net.
Useful to implement any protocol that uses BER (LDAP, SNMP, etc.).
A Java based, command-line analysis tool for checking the conformance of data streams to the formal definition they are supposed to adhere. The formal definition itself should comply to RFC 2234 Augmented BNF for Syntax Specifications: ABNF or ASN.1
netMANj is a network management software built on SNMP that is programmed in Java. It uses the OpenMap library from BBN for certain capabilities. It includes a set of libraries written from scratch for performing ASN encoding etc
Better ASN (developed by Thawte Technologies,) is a Java ASN.1 API that achieves near 100% encoding efficiency for typical ASN.1 usage. An ASN.1 to Java compiler is provided, facilitating custom extension of the API for any application.
The Cryptix ASN.1 Kit aims at facilitating the task programmers face in coding, accessing and generating java-bound, both types and values, defined as ASN.1 constructs, or encoded as such.
