Function hpke::single_shot_open

pub fn single_shot_open<A, Kdf, Kem>(
    mode: &OpModeR<'_, Kem>,
    sk_recip: &Kem::PrivateKey,
    encapped_key: &Kem::EncappedKey,
    info: &[u8],
    ciphertext: &[u8],
    aad: &[u8]
) -> Result<Vec<u8>, HpkeError>where
    A: Aead,
    Kdf: KdfTrait,
    Kem: KemTrait,

Does a setup_receiver and AeadCtxR::open in one shot. That is, it does a key decapsulation for the specified recipient and decrypts the provided ciphertext. See setup::setup_reciever and AeadCtxR::open for more detail.

Return Value

Returns Ok(plaintext) on success. If an error happened during key decapsulation, returns Err(HpkeError::DecapError). If an error happened during decryption, returns Err(HpkeError::OpenError).
