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
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
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
"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.
