# ASN.1

## Introduction

ASN.1 is a formal language for describing data structures to be exchanged
between distributed computer systems. The purpose of ASN.1 is to have a platform
and programming language independent notation to express types using a
standardized set of rules for the transformation of values of a defined type
into a stream of bytes. This stream of bytes can then be sent on any type of
communication channel. This way, two applications written in different
programming languages running on different computers, and with different
internal representation of data, can exchange instances of structured data
types.
