Expand description

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.

Implementations

impl<'a> TrustAnchor<'a>

pub fn try_from_cert_der(cert_der: &'a [u8 ]) -> Result<Self, Error>

Interprets the given DER-encoded certificate as a TrustAnchor. The certificate is not validated. In particular, there is no check that the certificate is self-signed or even that the certificate has the cA basic constraint.
