Struct HttpCryptContext 

pub struct HttpCryptContext { /* private fields */ }

Precomputed HTTPCrypt state for a fixed destination keypair.

Decoding the base32 peer public key and deriving the short key id used in the Key header depend only on the destination key, so they are done once at construction and shared by every request. Everything derived from ephemeral keys (scalarmult, shared secret, nonce) stays per-request.

Implementations

impl HttpCryptContext

pub fn new(peer_key_b32: &str) -> Result<Self, RspamdError>

Parse a base32-encoded remote public key into a reusable context.

pub fn key_header(&self, local_pk_b32: &str) -> String

Build the Key header value for an ephemeral local public key.

pub fn encrypt<T, HN, HV>( &self, url: &str, body: &[u8], headers: T, ) -> Result<HTTPCryptEncrypted, RspamdError>

where T: IntoIterator<Item = (HN, HV)>, HN: AsRef<[u8]>, HV: AsRef<[u8]>,

Encrypt a request for the destination this context was built for, generating a fresh ephemeral keypair.
