Struct rustls::RootCertStore

source ·
pub struct RootCertStore {
    pub roots: Vec<TrustAnchor<'static>>,
}
Expand description

A container for root certificates able to provide a root-of-trust for connection authentication.

Fields§

§roots: Vec<TrustAnchor<'static>>

The list of roots.

Implementations§

source§

impl RootCertStore

source

pub fn empty() -> Self

Make a new, empty RootCertStore.

source

pub fn add_parsable_certificates<'a>( &mut self, der_certs: impl IntoIterator<Item = CertificateDer<'a>>, ) -> (usize, usize)

Parse the given DER-encoded certificates and add all that can be parsed in a best-effort fashion.

This is because large collections of root certificates often include ancient or syntactically invalid certificates.

Returns the number of certificates added, and the number that were ignored.

source

pub fn add(&mut self, der: CertificateDer<'_>) -> Result<(), Error>

Add a single DER-encoded certificate to the store.

This is suitable for a small set of root certificates that are expected to parse successfully. For large collections of roots (for example from a system store) it is expected that some of them might not be valid according to the rules rustls implements. As long as a relatively limited number of certificates are affected, this should not be a cause for concern. Use RootCertStore::add_parsable_certificates in order to add as many valid roots as possible and to understand how many certificates have been diagnosed as malformed.

source

pub fn subjects(&self) -> Vec<DistinguishedName>

Return the DER encoded DistinguishedName of each trust anchor subject in the root cert store.

Each DistinguishedName will be a DER-encoded X.500 distinguished name, per RFC 5280 A.1, including the outer SEQUENCE.

source

pub fn is_empty(&self) -> bool

Return true if there are no certificates.

source

pub fn len(&self) -> usize

Say how many certificates are in the container.
