Build Status

eagre-asn1

eagre-asn1 is an asn1 library for Rust.

It makes heavy use of macros to make the interface easy to use.

Currently only DER and a very small bit of xer is supported.

Example

Say you have the following asn1 structure: 

  1. User ::= SEQUENCE {
  2.     username         UTF8String,
  3.     passwordHash     [CONTEXT 12] IMPLICIT OctetString,
  4.     age              [APPLICATION 1] EXPLICIT Integer,
  5.     admin            Boolean
  6. }

In Rust it would look like this: 

  1. struct User {
  2.     pub username: String,
  3.     pub password_hash: Vec<u8>,
  4.     pub age: i32,
  5.     pub admin: bool,
  6. }
  8. der_sequence!{
  9.     User:
  10.         username:      NOTAG                       TYPE String,
  11.         password_hash: IMPLICIT TAG CONTEXT 12;    TYPE Vec<u8>,
  12.         age:           EXPLICIT TAG APPLICATION 1; TYPE i32,
  13.         admin:         NOTAG                       TYPE bool,
  14. }

And serializing is as easy as: 

  1. use eagre_asn1::der::DER;
  3. let some_user = User { ... };
  4. let encoded = some_user.der_bytes().unwrap();
  5. // Send to far away planet
  6. let decoded = User::der_from_bytes(encoded).unwrap();
  7. assert_eq!(some_user, decoded);
