Expand description

Common trait for all objects that can be encoded using the DER representation

§Examples

Objects from this crate can be encoded as DER:

use asn1_rs::{Integer, ToDer};

let int = Integer::from(4u32);
let mut writer = Vec::new();
let sz = int.write_der(&mut writer).expect("serialization failed");

assert_eq!(&writer, &[0x02, 0x01, 0x04]);

Many of the primitive types can also directly be encoded as DER:

use asn1_rs::ToDer;

let mut writer = Vec::new();
let sz = 4.write_der(&mut writer).expect("serialization failed");

assert_eq!(&writer, &[0x02, 0x01, 0x04]);

Required Methods§

source

fn to_der_len(&self) -> Result<usize, Error>

Get the length of the object, when encoded

source

fn write_der_header( &self, writer: &mut dyn Write ) -> Result<usize, SerializeError>

Attempt to write the DER header to this writer.

source

fn write_der_content( &self, writer: &mut dyn Write ) -> Result<usize, SerializeError>

Attempt to write the DER content (all except header) to this writer.

Provided Methods§

source

fn to_der_vec(&self) -> Result<Vec<u8>, SerializeError>

Write the DER encoded representation to a newly allocated Vec<u8>.

source

fn to_der_vec_raw(&self) -> Result<Vec<u8>, SerializeError>

Similar to using to_vec, but uses provided values without changes. This can generate an invalid encoding for a DER object.

source

fn write_der(&self, writer: &mut dyn Write) -> Result<usize, SerializeError>

Attempt to write the DER encoded representation (header and content) into this writer.

§Examples
use asn1_rs::{Integer, ToDer};

let int = Integer::from(4u32);
let mut writer = Vec::new();
let sz = int.write_der(&mut writer).expect("serialization failed");

assert_eq!(&writer, &[0x02, 0x01, 0x04]);
source

fn write_der_raw(&self, writer: &mut dyn Write) -> Result<usize, SerializeError>

Similar to using to_der, but uses provided values without changes. This can generate an invalid encoding for a DER object.
