Struct webpki::TrustAnchor

pub struct TrustAnchor<'a> {
    pub subject: &'a [u8],
    pub spki: &'a [u8],
    pub name_constraints: Option<&'a [u8]>,
}

A trust anchor (a.k.a. root CA).

Traditionally, certificate verification libraries have represented trust anchors as full X.509 root certificates. However, those certificates contain a lot more data than is needed for verifying certificates. The TrustAnchor representation allows an application to store just the essential elements of trust anchors. The webpki::trust_anchor_util module provides functions for converting X.509 certificates to to the minimized TrustAnchor representation, either at runtime or in a build script.

Fields

subject: &'a [u8]

The value of the subject field of the trust anchor.

spki: &'a [u8]

The value of the subjectPublicKeyInfo field of the trust anchor.

name_constraints: Option<&'a [u8]>

The value of a DER-encoded NameConstraints, containing name constraints to apply to the trust anchor, if any.
