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 anyhow
This crate provides the primitives for parsing ASN.1 data. The user has full control on how to interpret the bytes.
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));
