Struct CertCache 

pub struct CertCache { /* private fields */ }

In-memory certificate cache.

Certificates are just named Data packets — fetching one is a normal NDN Interest. The cache avoids re-fetching recently validated certificates.

Two indices are maintained: by certificate name (the canonical lookup used when a packet’s KeyLocator carries a Name), and by SHA-256 of the public key (used when the locator carries a KeyDigest). Both are populated on insert so callers do not need to know which form a future verification will use.

Implementations

impl CertCache

pub fn new() -> Self

pub fn get(&self, key_name: &Arc<Name>) -> Option<Certificate>

pub fn get_by_key_digest(&self, digest: &[u8]) -> Option<Certificate>

Look up a certificate by the SHA-256 of its public key — used to resolve KeyLocator → KeyDigest references. Only matches certificates already in the cache: KeyDigest cannot be used to fetch a certificate over the network because the cert’s name is not known to the caller.

pub fn insert(&self, cert: Certificate)

Trait Implementations

impl Default for CertCache

fn default() -> Self

Returns the “default value” for a type.
