ring-der

This crate providers an extended version of the DER parser in ring::io::der.

What's extended:

• All tag types as defined in X.680 section 8.4;
• High tag number, for tag numbers 31 and greater;
• Error handling with thiserror.

Example

use ring_der::der::parse_boolean;
use ring_der::Error;

let input = untrusted::Input::from(&[0x01, 0x01, 0xff]);
let result = input.read_all(Error::IncompleteRead, |r| parse_boolean(r));
assert_eq!(result, Ok(true));
