Crate bcder

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.

The most important modules of the crate are decode and encode that provide the machinery for implementing decoding and encoding of data.

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, Captured provides a way to keep encoded data around for later processing.
