ASN.1 DER-encoded document.

This trait is intended to impl on types which contain an ASN.1 DER-encoded document which is guaranteed to encode as the associated Message type.

It implements common functionality related to encoding/decoding such documents, such as PEM encapsulation as well as reading/writing documents from/to the filesystem.

Required Associated Types

type Message: Decodable<'a> + Encodable + Sized

ASN.1 message type this document decodes to.

Required Associated Constants

const SENSITIVE: bool

Does this type contain potentially sensitive data?

This enables hardened file permissions when persisting data to disk.

Provided Methods

fn as_der(&self) -> &[u8]

Borrow the inner serialized bytes of this document.

fn to_der(&self) -> Box<[u8]>

Return an allocated ASN.1 DER serialization as a boxed slice.

fn decode(&'a self) -> Self::Message

Decode this document as ASN.1 DER.

fn from_der(bytes: &[u8]) -> Result<Self>

Create a new document from the provided ASN.1 DER bytes.

fn from_msg(msg: &Self::Message) -> Result<Self>

Encode the provided type as ASN.1 DER.

fn from_pem(s: &str) -> Result<Self>where Self: PemLabel,

Decode ASN.1 DER document from PEM.

fn to_pem(&self, line_ending: LineEnding) -> Result<String>where Self: PemLabel,

Encode ASN.1 DER document as a PEM string.
