Struct DerEncoder 

pub struct DerEncoder { /* private fields */ }

DER encoder: builds a byte vector by appending TLV items.

Implementations

impl DerEncoder

pub fn new() -> Self

Create a new empty encoder.

pub fn finish(self) -> Vec<u8>

Return the encoded bytes.

pub fn write_length(&mut self, len: usize)

Append a raw DER length.

pub fn sequence(&mut self, content: &[u8])

Append a SEQUENCE wrapping the given content.

pub fn integer(&mut self, value: &[u8])

Append an INTEGER from big-endian unsigned bytes. Adds a leading 0x00 if the MSB is set (to keep it positive).

pub fn integer_u64(&mut self, v: u64)

Append a small non-negative INTEGER from a u64 (for version fields).

pub fn octet_string(&mut self, data: &[u8])

Append an OCTET STRING.

pub fn bit_string(&mut self, data: &[u8])

Append a BIT STRING (with zero unused-bits prefix).

pub fn oid(&mut self, encoded: &[u8])

Append an OBJECT IDENTIFIER from its encoded byte form.

pub fn null(&mut self)

Append a NULL.

pub fn context_explicit(&mut self, tag_num: u8, content: &[u8])

Append an explicit context-tagged [N] CONSTRUCTED wrapping.

pub fn raw(&mut self, data: &[u8])

Append raw bytes (for building inner content).
