Usage

The following example demonstrates how to use an OID as the parameters of an AlgorithmIdentifier.

Borrow the ObjectIdentifier first then use der::AnyRef::from or .into():

use spki::{AlgorithmIdentifier, ObjectIdentifier, der::AnyRef};

let alg_oid = "1.2.840.10045.2.1".parse::<ObjectIdentifier>().unwrap();
let params_oid = "1.2.840.10045.3.1.7".parse::<ObjectIdentifier>().unwrap();

let alg_id = AlgorithmIdentifier {
    oid: alg_oid,
    parameters: Some(AnyRef::from(&params_oid))
};
