This crate provides decoding and encoding for Basic Encoding Rules (BER) of the ASN.1 standard as well as the more strict variants Canonical Encoding Rules (CER) and Distinguished Encoding Rules (DER). It provides the basic machinery as well as implementation for the most important universal types of ASN.1.

Handling of data in Basic Encoding Rules.
This crate allows decoding and encoding of data encoded in ASN.1’s Basic Encoding Rules as defined in ITU recommendation X.690 as well as their stricter companions Cannonical Encoding Rules and Distringuished Encoding Rules.
You will find a short introduction to ASN.1 and encoding rules as well as a discussion of how decoding and encoding with the crate work in the guide module. The documentation with all the other modules serves as a reference documentation.
Additionally, the crate provides a number of types that help dealing
with the more difficult universal types in ASN.1. Specifically, the
module int provides variable length integers, the module
string contains types for the various kinds of strings defined in
ASN.1, and oid deals with object identifiers. Finally,
provides a way to keep encoded data around for later processing.
