Welcome to serde_asn1_der 🎉

This crate implements an ASN.1-DER subset for serde based upon asn1_der.

The following types are supported:

  • bool: The ASN.1-BOOLEAN-type
  • u8, u16, u32, u64, u128, usize: The ASN.1-INTEGER-type
  • (), Option: The ASN.1-NULL-type
  • &[u8], Vec<u8>: The ASN.1-OctetString-type
  • &str, String: The ASN.1-UTF8String-type
  • And everything sequence-like combined out of this types

With the serde_derive-crate you can derive Serialize and Deserialize for all non-primitive elements:

use serde_derive::{ Serialize, Deserialize };

#[derive(Serialize, Deserialize)] // Now our struct supports all DER-conversion-traits
struct Address {
	street: String,
	house_number: u128,
	postal_code: u128,
	state: String,
	country: String

#[derive(Serialize, Deserialize)] // Now our struct supports all DER-conversion-traits too
struct Customer {
	name: String,
	e_mail_address: String,
	postal_address: Address


use serde_asn1_der::{ to_vec, from_bytes };
use serde_derive::{ Serialize, Deserialize };

#[derive(Serialize, Deserialize)]
struct TestStruct {
	number: u8,
	#[serde(with = "serde_bytes")]
	vec: Vec<u8>,
	tuple: (usize, ())

fn main() {
	let plain = TestStruct{ number: 7, vec: b"Testolope".to_vec(), tuple: (4, ()) };
	let serialized = to_vec(&plain).unwrap();
	let deserialized: TestStruct = from_bytes(&serialized).unwrap();


This crate also offers a type-erased AnyObject-trait, that allows you to use Box<dyn AnyObject> instead of a specific type. To enable AnyObject, use the "any"-feature.
