# picky-asn1-der

Portions of project [serde_asn1_der](https://github.com/KizzyCode/serde_asn1_der) are held by
Keziah Biermann, 2019 as part of this project.

This crate implements an ASN.1-DER subset for serde.

The following types have built-in support:
 - `bool`: The ASN.1-BOOLEAN-type
 - `u8`, `u16`, `u32`, `u64`, `u128`, `usize`: The ASN.1-INTEGER-type
 - `()`: The ASN.1-NULL-type
 - `&[u8]`, `Vec<u8>`: The ASN.1-OctetString-type
 - `&str`, `String`: The ASN.1-UTF8String-type

More advanced types are supported through wrappers:
- Integer (as big integer)
- Bit String
- Object Identifier
- Utf8 String
- Numeric String
- Printable String
- IA5 String
- Generalized Time
- UTC Time
- Application Tags from 0 to 15
- Context Tags from 0 to 15

Everything sequence-like combined out of these types is also supported out of the box.
