The ASN.1 Toolkit is a collection of software components for Linux, MS Windows, and possibly MacOS (future - if I get this stuff compiled for Intel/ARM64 Macs)...

It is pure 64bit software written in pure C (Java Native Interface wrappers are on the roadmap).

One of the main goals of the ASN.1 toolkit was to provide a symbolic ASN.1 database to provide an awesome ASN.1 dump tool with symbolic support.

But it has become far more. Please read the main section below to get into it. My claim is "flat ASN.1 processing was y′day!"

The ASN.1 Toolkit - The F.A.T.Book

The F.A.T.Book is a cross-reference of Famous ASN.1 Types (and values).

It is available as a PDF document with full PDF link support: Download the PDF here.
