asn1-cereal

A collection of encoders and decoders for BER, DER and ASN.1.

The grains of this library are a collection of traits and macros that allow serialization and deserialization of rust types to and from ASN.1. For example, the following will encode this struct as a DER sequence.

#[macro_use]
extern crate asn1_cereal_derive;
extern crate asn1_cereal;
fn main() {
  #[derive(Asn1Info, BerSerialize, BerDeserialize)]
  #[asn1(asn1_type="SHORT_SEQUENCE", tag="[APPLICATION 8]")]
  struct ShortSequence {
    z: u64,
    y: u32,
  }

  use asn1_cereal::BerSerialize;

  let data = ShortSequence{ z: 1, y: 2 };
  let mut bytes: Vec<u8> = Vec::new();
  BerSerialize::serialize(&data, &mut bytes).unwrap();
}
