Struct TlsCertificate 

pub struct TlsCertificate {
    pub der: Vec<u8>,
}

A TLS certificate wrapping raw DER-encoded X.509 data.

Fields

der: Vec<u8>

Raw DER-encoded certificate data.

Implementations

impl TlsCertificate

pub fn from_der(der: Vec<u8>) -> Self

Create from DER-encoded bytes.

pub fn from_pem(pem: &str) -> Option<Self>

Create from PEM-encoded string.

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

Get the DER-encoded data.

pub fn len(&self) -> usize

Get the certificate length.

pub fn is_empty(&self) -> bool

Check if empty.

pub fn subject_cn(&self) -> Option<String>

Extract the subject common name (CN) from the certificate.

This is a basic ASN.1 parser that looks for the CN OID (2.5.4.3). In X.509, issuer comes before subject, so subject CN is the second occurrence. For self-signed certs (only one CN), falls back to the first occurrence.

pub fn issuer_cn(&self) -> Option<String>

Extract the issuer common name from the certificate.

Trait Implementations

impl Clone for TlsCertificate

fn clone(&self) -> TlsCertificate

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TlsCertificate

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
